Introduction to COMTRADE

EnerVista PMCS supports the C37.111-1991 and C37.111-1999 COMTRADE Standards. The Comtrade Viewer feature within EnerVista PMCS provides a visual display of power systems data and relay operation data captured during a specific triggered event. The triggering of waveforms is determined by the settings made in the device. There are no default device settings for capturing waveforms, each device MUST be configured with the triggers. Triggers and settings are determined by the device owner.

This introduction will focus only on viewing retrieved waveforms. If there are no waveforms retrieved then the device must be configured to generate one.
