Abstract:
An energy information system for use with a circuit breaker coupled between a power source and a load, the energy information system comprising:sensing means for sensing at least one of i) a voltage, and ii) a current flowing between the power source and the load through the circuit breaker;detecting means for detecting transitions of a sensed voltage;counting means for counting a number of times the circuit breaker trips and interrupts the current flow between the power source and the load;measuring means for i) measuring the current flow through the circuit breaker when the circuit breaker trips and interrupts the current flow between the power source and the load and ii) determining a plurality of energy related parameters including a measure of at least one of the voltage, the current and the frequency based on an output from the detecting means, between the power source and the load;input means for accepting a user input, the user input controlling at least one of the circuit breaker and a display means;the display means for displaying at least one of the plurality of conditions of the circuit breaker responsive to the input means; andcommunication means coupled to the input means for selectively communicating at least one of the plurality of energy related parameters to a remote terminal.
