Abstract:
1. An electrical fault restricting system for an electrical equipment and/or an electrical system, the electrical fault restricting system comprising: a sensing device for sensing fault conditions at a location of a fault and a measuring device measures a signal of earth fault current from the electrical equipment and/or electrical system, the signal sensed by the sensing device or measuring device being directly proportional to electrical fault conditions of a fault path at a point of an electrical fault; the sensing device and the measuring device are installed at location of interest and further connected to monitoring units; said monitoring units continuously monitor an input fed from the sensing device and the measuring device such that the electrical fault conditions are sensed and measured at the fault location the signal sensed by the sensing device or measuring device are collected at monitoring units and such signals are amplified and further sent to signal processing and controlling unit; a signal processing and controlling unit being installed near or remote to the monitoring unit, the signal processing and controlling unit adapted to an alarming and indication unit performs alarms and indications about fault on basis of output provided by the processing and controlling unit; an image collector with the sensing device being connected to said signal processing and controlling unit for taking images of the electrical fault conditions at the location of interest as sensed and measured by the sensing device and the measuring device in the electrical equipment and/or electrical system; a data history storage and display unit for storing data received from output of the signal processing and controlling unit; and a remote central controlling and data handling unit being connected to the signal processing and controlling unit for effective fault restriction.
