Key Features
Synchrophasor measurement devices (PMU) that meet IEEE c37.118 (2014) across all protection applications
Synchrophasor capabilities on generator, transformer, line distance, line differential and feeder applications
Multiple configurable PMU elements (up to 6 on selected products)
Extended Oscillography – captures extended events at 64 samples per cycle
Event Recorder – 1024 time tagged events, with 0.5ms scan of digital inputs
Data Logger – up to 16 channels with user selectable sampling rate
Fault locator and user-programmable fault reports
Breaker condition monitoring including breaker arcing current (I2t)
Metering – current, voltage, power, power factor, frequency
Broken Rotor Bar Detection and motor temperature via RTD inputs
Monitoring & Diagnostics
The UR includes high accuracy metering and recording for all AC signals. Voltage, current, and power metering are built into the relay as a standard feature. Current and voltage parameters are available as total RMS magnitude, and as fundamental frequency magnitude and angle.
