Abstract

See full text

A circuit monitoring system for a distributed power network employs waveform capturing techniques for efficient and highly accurate monitoring. The system includes a plurality of circuit monitors and a control station, which is coupled to each of the circuit monitors via a multi-drop communications link. Each of the circuit monitors is disposed adjacent an associated one of the branches in the network for sensing power parameters in the branches and for generating and transmitting data representing the power parameters to the control station The control station is used for generating monitoring commands to each of the circuit monitors to provide the system with full system control and evaluation capability. Each of the circuit monitors also includes EEPROM memory for storing and retaining operational data, sent from the control station, in the absence of power. This allows a microcomputer in the circuit monitor to read the retained data for analyzing the sensed power parameter.
