Description
The analog inputs accept bay currents and voltages, and the digital inputs capture signals from switching devices and protection. The galvanic isolation of the inputs is up to 2 kV RMS. Records are stored in COMTRADE format, so standard waveform analysis software opens them. Access is remote, so records are retrieved without a site visit.
