Title: Device and method for detecting faulty electrical circuits with fault identification and alert system

Description:
A) TECHNICAL FIELD 
     The present invention generally relates to the field of electrical circuits fault detection device and method. More particularly, the present invention is aimed at providing a device and method, which facilitates in protecting home or industrial appliances against any electrical mishaps or surges due to faulty circuits and components, identifying the problem source for the electrical mishap and providing alerts to the user or the technician regarding the source of the problem or the electrical mishap through any of the available communication means. 
     B) BACKGROUND OF THE INVENTION 
     The electrical systems in residential, commercial and industrial applications usually include a panel board for receiving electrical power from a utility source. The received power is then routed through overcurrent protection devices to designated branch circuits or electrical outlets supplying one or more loads. These overcurrent protection devices are typically circuit interrupters such as circuit breakers and fuses which are designed to interrupt the electrical current if the limits of the conductors supplying to the loads are surpassed. Interruption and breaking the circuit reduces the risk of injury or the potential of property damage from a resulting fire. 
     Circuit breakers are a preferred type of circuit interrupter because a resetting mechanism allows their reuse. Typically, circuit breakers interrupt an electric circuit due to a disconnect or a trip condition such as a current overload or ground fault. The current overload condition results when a current exceeds the continuous rating of the breaker for a time interval determined by the trip current. A ground fault trip condition is created by an imbalance of currents flowing between a line conductor and a neutral conductor which could be caused by a leakage current or an arcing fault to ground. 
     Arcing faults are commonly defined as current through ionized gas between two ends of a broken conductor or at a faulty contact or connector, between two conductors supplying a load, or between a conductor and ground. However, arcing faults may not cause a conventional circuit breaker to trip. Arcing fault current levels may be reduced by branch or load impedance to a level below the trip curve settings of the circuit breaker. In addition, an arcing fault, which does not contact a grounded conductor or person, will not trip a ground fault protector. 
     There have been several attempts drawn to identify the faulty electrical lines and electrical circuit installations but eventually none of them provide a full fledge solution in providing the solution for the identified problem. One such patent application W02008049436A1 titled “Method and device for location of loose connection”, in which a microprocessor and at least one detection means is being provided for detecting a high frequency pulse in the current in at least one phase. The detection means comprises a first detector located on the user side and a second detector located on the supply side, as well as a comparing means for delivering a detection signal to the microprocessor based on detector signals from the first detector and the second detector. The microprocessor herein is being programmed to evaluate a number of successive detection signals. However, the above-mentioned patent application fails to provide relevant real-time advices/suggestions and accurate communication to the concerned technician/user through any of the available communication means. 
     Further, the patent application U.S. Pat. No. 5,250,909A titled “Automatic fault detection in electrical sensing circuits”, continuously monitors the operational status of the sensing circuit. Generally open sensors are provided with a resistance across the open circuit contacts to provide a small leakage current. For each sensor, a high and a low comparators are provided. The high comparator is ground seeking and is used to detect closure of open circuit sensors, grounded connections and systems tests. The low comparator detects open circuits or high resistances such as might be caused by broken or loose wires, improperly connected sensors or electrically degraded sensors. The comparators drive logic components, which in turn drive indicators of circuit operational readiness. Unfortunately, the above-mentioned patent document fails to provide relevant real-time advices/suggestions and accurate communication to the concerned technician/user through any of the available communication means. 
     Therefore, there exist many conditions that may cause electrical surges such as arcing faults, short circuit, neutral loss, over voltage, under voltage, voltage surge, phase loss, voltage harmonics and phase reversals. These faults may damage the appliances and allowing the connected wiring circuits to reach unacceptable temperatures. Adding to this, arcing faults due to faulty circuits or faulty electrical components can also cause fire if combustible materials are in close proximity leading to electrical mishap. 
     Hence, the existing solutions for electrical safety are inadequate as they are not able to detect all electrical issues. A significant challenge in using these electrical safety devices is due to nuisance tripping (or perceived nuisance tripping). Often time electrical safety devices are not able to identify fault correctly. They trip more often than they should. Even if the electrical safety devices trip correctly, many times it is extremely difficult and time consuming to find the source of the problems. Without adequate tools, it is close to impossible to identify the root cause of the problem and as a result, the electrical safety device is disconnected or bypassed. 
     Adding to this, even if the source or root cause of the electrical problem is identified, providing timely and real time alerts to the users and concerned technicians has always remained as a challenge. Hence, in the view of the foregoing, there exist a need to provide a device and method, which facilitates in identifying faulty circuits, faulty electrical components and provide automated protection to home and industrial appliances against any electrical mishaps caused due to electrical faults. Further, there also exist a need to provide a device and method, which facilitates in providing real-time or timely alerts to the end-users or other related technicians, indicating the source of the problem, severity of the electrical faults and communicating the same with advices/suggestions with the end-user or to the concerned technician through any of the onboard communication means. 
     The above-mentioned shortcomings, disadvantages and problems are addressed herein, which will be understood by reading the following specification. 
     C) OBJECTS OF THE INVENTION 
     The primary object of the present invention is to provide an electrical safety device and method for identification of faulty electrical circuits or electrical installations, electrical components and outlets with real-time alerts/suggestion or advice related to the identified fault being communicated to the end-user and other technicians depending on the severity about the fault. 
     The other object of the present invention is to provide an electrical safety device and method that identifies electrical signatures leading to electrical faults that are not only harmful to individuals and assets but can also lead to fires.

     Another object of the present invention is to provide an electrical safety device and method that provide early indicators for the critical faults and provide advice or suggestions to the end-user or to the concerned technician on the corrective steps to be followed.

     F) DETAILED DESCRIPTION OF THE INVENTION 
     In the following detailed description, reference is made to the accompanying drawings that form a part hereof, and in which the specific embodiments that may be practiced is shown by way of illustration. These embodiments are described in sufficient detail to enable those skilled in the art to practice the embodiments and it is to be understood that the logical, mechanical and other changes may be made without departing from the scope of the embodiments. The following detailed description is therefore not to be taken in a limiting sense. 
     The embodiments of the present invention provides an electrical safety protection device for detecting faulty electrical circuits with fault location identification and alert system. The existing solutions for electrical safety protection systems are inadequate as they are not able to detect much or all of the electrical issues. A significant challenge in using these electrical safety devices is due to nuisance tripping (or perceived nuisance tripping). The most common reason for nuisance tripping is a transient current to ground, which is above the threshold of the RCD (Residual Current Devices) and subsequently causes the RCD to trip. Often time RCD devices are not able to identify fault correctly and they trip more often than they should. Even if the electrical safety devices RCD devices trip correctly it is many a times extremely difficult and time consuming to find the source of the problems. Without adequate tools, it is close to impossible to identify the root cause of the electrical problem and as a result, the electrical safety device is disconnected or bypassed. 
     In an attempt to address the above-mentioned problem, the proposed solution is to have electrical safety and protection device connected to each circuit either in the distribution board or at each individual outlet. These patterns of electrical safety and protection device installations enables the end-users or the technicians to monitor the electrical lines and electrical appliances for normal and safe operation at a micro level. 
     In the proposed invention, the electrical safety and protection device is primarily installed at the domestic electricity receiving distribution panel where we generally receive incoming power lines from the public electrical junctions/feeds. The electrical safety and protection device intakes power lines from the energy meter and distributes the power to the domestic appliances through the electrical safety and protection device. This enables the electrical safety and protection device to check the received electrical signatures, if they are safe to be relayed to the domestic or industrial appliances for normal operation. It is to be observed that the electrical safety and protection device receives incoming power lines through incoming switches, which comprises of but not limited to an input switch, an arc quenching, a bimetallic strip and a solenoid. 
     The electrical safety and protection device identifies the electrical signatures leading to electrical faults that are not only harmful to individuals and assets but can also lead to fires and other electrical mishaps. Moreover, the electrical safety and protection device provides a solution that is connected as a single device for monitoring multiple circuits connected within a distribution board. Further, the electrical safety and protection device can determine the cause and location of an electrical fault hence making it easier to fix the electrical fault. Another aspect of electrical safety and protection device is that the device is able and configured to give early indicators for the critical faults and advice on the corrective steps. 
     According to the embodiment, the electrical safety and protection device comprises of at least one or more incoming switches, a voltage sensing component, a current sensing component, a high frequency current sensing component, a core balanced transformer component, a voltage filter component, a microcontroller, a powering means to power the entire device for normal operation, a display means to display various parameters related to received voltage or current and one or more communication components. 
     Wherein, one or more incoming switches receive the incoming power supply, which in turn supplies the power to the voltage sensing, current sensing, high frequency current sensing and core balance transformer. The power signals sensed by the voltage sensing component, current sensing component, high frequency current sensing component and core balance transformer component is fed into the filtering component. The filtering component allows passing the DC component of the load and blocks the AC component of the rectifier output. Thus, the output of the filter circuit will be a steady DC voltage whose values are readable by semiconductor components such as microcontrollers. 
     Further, the DC component or the DC voltage from the filter is fed into the microcontroller component; wherein the microcontroller component monitors and analyses the received voltage from the filter circuit pertaining to the input power supply received by the electrical safety and protection device. The microcontroller on receiving the input voltages from the filter component, the microcontroller converts the received analog voltage into digital signals. These digital signals are processed with a pre-coded and an inbuilt software method in the microcontroller, thereby making necessary calculations in deciding to cut off the incoming power supply or not. If the electrical safety and protection device senses the incoming power supply to be at dangerous levels, the microcontroller on the electrical safety and protection device outputs trip/switch off signals to the solenoid present in the incoming switch to isolate and cut off the incoming power supply. 
     The microcontroller further provides various data to be displayed onto the display component. These data include such as but not limited to information regarding the occurred fault, status of the power supply, faulty power lines, location of the fault, time and date stamp of the occurred fault, suggestion or advice for the identified fault and concerned technician to be contacted with the relevant technician&#39;s contact information. These displayed data is also transmitted or communicated to the end-user through any of the available wired or wireless means of communication configured in the installed electrical safety and protection device. 
     The wired communication means can be such as but not limited to communicating data through an active internet connection, LAN/Ethernet based communication or a dial-up phone line communication. The wireless communication means include such as but not limited to GSM/GPRS based communication, wireless internet communication, Bluetooth based communication, NFC communication, data communication over a Wi-Fi, Modbus communication and long-range communications devices. 
     It is to be understood that the electrical safety and protection device is also capable of housing a GPS (Global Positioning Device) in order to share the location with the technicians and other end-users. Further, the microcontroller component report the type and the geospatial location of the fault to a predefined set of individuals through one or more communications means such as but not limited to SMS, email or cloud based communications. The reference parameters for the method present in the device, which identifies faulty electrical circuits with fault identification and alert system, can be re-programmed over the air through the any of the available communication means to provide the parameters and other settings to the electrical safety and protection device. 
     Further, the method present in the microcontroller is capable of automatically registering a complaint regarding the occurred fault, by communicating to any of the external complaint computer servers through any of the available communication means and communication components. 
     The microcontroller component employs a pattern matching method to match the patterns of received different electrical loads and identify the loads that are operational at a given instance of time. The pattern matching methods are used during the time of electrical faults identification to match any variations in the electrical parameters and/or transformations. The pattern matching methods employed herein includes like but not limited to DCT, Taylor&#39;s, neural network pattern detectors and other learning algorithms, which are performed on the received electrical parameters such that the device learns weights and functions based on these received data. 
     The pattern matching is performed on geographical data, types of loads, type of installation as well as normal patterns in case of clusters of loads with similar patterns. Further, the microcontroller comprises of an embedded method that identifies and interprets electrical fault signatures in real time corresponding to electrical failure, to create early warning alarms based on the threshold values and to isolate the incoming power supply based on one or more defined threshold values or data. According to the embodiment, the solenoid is turned into ON/OFF state depending on the received power supply from the incoming switches. The source of the electrical fault is identified by monitoring and comparing the change in parameters such as KW, KWH, KVA, PF and other such harmonics. Hence, the device can identify any deviations in the electrical parameters and provide an early warning for preventive maintenance. 
     Further to this, an additional battery and a button will be provided for a low voltage DC power to activate the system even when the incomer is switched off. This button is used to power on the device and report the history of electrical faults and existing electrical faults on the display screen while the incomer power is switched off. 
       FIG. 1  illustrates the component diagram of an electrical safety protection device indicating various components of the system and their interconnections with the other sub-components according to the embodiment of the invention. Accordingly, the electrical safety and protection device  303  comprises of at least one or more incoming switches  108 , at least one voltage sensing component  104 , a current sensing component  105 , at least one high frequency current sensing component  106 , at least one core balanced transformer component  107 , at least one voltage filter component  102 , at least one microcontroller  101 , a powering means to power the entire device for normal operation  103 , a display means  110  to display various parameters related to received voltage or current and one or more communication components  111  and  112  for communicating and receiving data from external devices. 
     The incoming switches  108  receives the input power supply from the public electrical feeds through an energy meter and in turn is fed to the voltage sensing component  104 , current sensing component  105 , high frequency current sensing component  106  and core balance transformer component  107 , present on the electrical safety and protection device  303 . The low frequency current sense circuit  105  is used to convert the low frequency input current signal to a low voltage signal that can be measured by the microcontroller  101 . Typically, current transducers are used here and are tuned to accurately measure the low frequency signals. 
     The high frequency current sense circuit  106  is used to amplify the high frequency input current signal to a voltage signal so that it can be measured by the microcontroller  101 . Further, a core balanced transformer  107  is a circuit that is used to identify the earth leakage currents observed in the circuits. These sensors ( 104 ,  105 ,  106  and  107 ) provide the sensed power inputs to the filtering component  102  wherein the filtering circuits  102  are used to condition and convert the signals received from the voltage sense component  104 , low frequency current sense component  105 , high frequency current sense component  106  and core balanced transformers  107  to improve the signal to noise ratio and bring it at a voltage level that is easily measured by the Analog to digital converters present in the microcontrollers  101 . 
     The microcontroller component  101  monitors/analyses the received voltage signals, which pertains to the incoming signals to the electrical safety and protection device  303 . The microcontroller  101  takes input voltage signals from the filtering circuit  102 , makes calculations and outputs signals to solenoid present in the incoming switch  108  determining weather to isolate the incoming power supply or not. The solenoid that works as a switch, switches the incoming power supply into ON or OFF state depending upon the voltage values and instructions received and processed by the microcontroller  101 . 
     The microcontroller  101  also provides various data and information to be displayed onto the display component  110  and the communication data is provided to communication component  111  and  112  which are to be transmitted to one or more external devices. The display means  110 , which is at least a LCD display component, is used to display data such as but not limited to metering data, details of warnings and faults; to the end-user or to other concerned technicians. The data received by the communication component  111  and  112  is transmitted to the end user or to the concerned technicians or to the external devices such as servers that store data on the cloud, through any of the wired or wireless means of communication where the transmitted data indicates and includes information relating to such as but not limited to status of the power supply, faulty power lines, location of the fault, severity of the fault and other such information. 
     Further, the pre-programmed method in the microcontroller  101  can be re-programmed in a manner such that the electrical faults can be categorized into various levels with fault severity, suggested technician to be contacted and the end-users to be informed about various levels of electrical faults with advices/suggestions about the fault, can also programmed and fed into device  303 . The persons (end-users and technicians) to be informed for various levels and severity of electrical faults and their respective communication details such as but not limited to phone number and email address can be programmed and stored into the device&#39;s  303  memory. In continuation, the device is also capable of locating the location of the electrical fault and its severity with possible suggested and recommended measures, which are to be communicated to the end-users and the relevant technicians. 
     As an example, any problem with the electrical components or electrical wiring, the owner/end-user of the premises with the associated electrical technician gets an alert message with the severity of the problem and its location with possible solutions/advices/suggestions for the problem. Similarly, if the problem or fault is related to the incoming or the input electricity to the premises, the device  303  sends the relevant signals to the solenoid to shut the incoming power supply and the device  303  transmits the message relating to the fault to the owner/end-user of the premises with the associated electrical lineman wherein the transmitted message includes but not limited to the severity of the problem, its location with possible solutions/advices/suggestions. Hence, this eases the problem where the end-user calling the irrelevant persons for rectifying the problems. Hence, this automation of sending messages to the concerned person helps in communicating the relevant problem to relevant person in real time. 
     Further the incoming switches  108  comprise input switch which are one or more mechanical and electro-mechanical switches that are used to turn ON or OFF the device. While, the device tries to break a fault signal, high currents known as arc are observed. The arc quenching device in the incoming switches  108  is used to control and quench the arc so that it does not create damage to other components in the system. The bimetallic strip is used to sense high currents and isolate the incoming switch. Further, a solenoid is an electromechanical device, wherein an electrical pulse is given to trigger a mechanical motion that will in turn trigger to isolate the incomer switch  108 . 
     Finally, the device includes a AC to DC converter power supply  103  which is used to power all the internal circuits of the device for normal functioning. 
       FIG. 2  illustrates the system flow diagram illustrating the series of steps starting from installing the electrical safety protection device at the target location and continuously monitoring the incoming electrical signals for any faults, according to the embodiment of the invention. Accordingly, the device for monitoring and detecting faulty electrical circuits with fault identification and alert system is installed in the power panel  201 . The installed device monitors the incoming and outgoing power connections  202  and if any fault is located in any of the wiring systems (internal and external), power appliances or power components, a immediate alert is sent  203  through any of the available communication channels to the end-users/the relevant technicians/or to an external computing devices—indicating the source of the problem, severity of the problem and possible suggested solutions/Advices  204 . The display panel in the electrical safety and protection device  303  displays information relevant to the fault and the point of electrical installation the fault is detected is also displayed. The electrician or the specified designated technical persons addresses the issue and resets the information  205 . Once the device is reset, the device starts working normally and continues monitors the circuits  206  ensuring the safety of the users and the connected electrical components  207 . 
       FIG. 3  illustrates the installation and wiring diagram of the electrical safety protection device at the target location according to the embodiment of the invention. Accordingly, the electrical safety and protection device  302  is installed between the incoming power supply through the energy meter  301  and the distribution box  303 . The incoming power lines from the public power utility is drawn to the energy meter  301  and then routed to the electrical safety and protection device  302 . The electrical safety and protection device  302  is positioned such that the incoming power lines from the energy meter  301  has to go through the electrical safety and protection device  302  and then reach the distribution box  303  for it to be supplied for one or more appliances  304 . In case, the electrical safety and protection device  302  senses any fluctuation in the incoming power signals/senses any wiring issues or identifies any fault in the connected electrical components, the electrical safety and protection device  302  sends out a signal to the solenoid present in the input switch  108  to trip OFF the incoming power supply, thereby ensuring no further damages to the connected appliances  304  in the circuit. The electrical safety and protection device  302  uses a pattern matching method present in the microcontroller and in a local server with the one in the cloud server, to match the patterns of received different electrical loads and identify the loads that are operational at a given instance of time. 
     Hence, the induction of the electrical safety and protection device  302  ensures that the incoming power lines are scanned for any fluctuations and connected circuitries are monitored continuously for any fault thereby protecting the connected appliances.
