Abstract

A circuit monitoring system for performing synchronized waveform capture. A waveform capture trigger communication network interconnects a plurality of monitoring devices. The system provides direct device to device trigger communication between monitoring devices in a synchronized group. Power system waveform data is stored in the monitoring device memory of all members of the synchronized group in response to a trigger event initiated by any monitoring device in the synchronized group. High speed trigger communication results in substantially simultaneous waveform capture among the members of the synchronized group.
