A method and apparatus for monitoring multi-phase alternating current signals and providing a signal representative of each phase current signal. Each alternating current signal is rectified by a direct current output rectifier to generate a signal representative of both the phase and magnitude of the alternating current signal. The method and apparatus also provides for using the output signal to operate a circuit breaker in a ground fault detection system.

Method and apparatus for alternating current monitoring with phase and

An electrical apparatus (100) line actuator (102), such as a voltage regulator or circuit breaker, has resident therein a personality module, electronically reconfigurable memory device (126) which stores actuator operational information, such as specifications (132), historical and maintenance information. An apparatus controller (106) communicates with the personality module (126) and can change the operational information stored therein. If either or both of the controller (106) and actuator (102) is replaced at a site, the controller (106) of the replacement apparatus configuration (100) can read the operational information stored in the personality module (126) and adapt its operational interaction with the actuator (102) in conformance with the information.

A low voltage AC electric power monitoring system includes a processor which samples the current and circuit breaker system includes a processor which samples each of the current components at seventeen samples per cycle to obtain current samples representing a single period of the AC power signal. The processor samples the voltage component at different points in the voltage cycle over several cycles to obtain voltage samples representing a single period of the AC power signal.
