Voltage, current, and power metering are built into the protection platform as a standard
feature. Current parameters are available as total waveform RMS magnitude, or as
fundamental frequency only RMS magnitude and angle (phasor).
Measured values include:
• Voltage phasors.
• Voltage symmetrical components.
• Current phasors.
• Current symmetrical components.
• Current true one-cycle RMS values.
• Active, reactive, and apparent power.
• Power factor (all power values per phase and total).
• Four-quadrant energy.
• Frequency.
• Synchrophasors.
• Data logger.
The measured signals are available for larger local display in the color LCD, accessible
remotely using communications.
The metered values for real, reactive, and apparent power, as well as power factor, are
displayed via the front panel interface or through the EnerVista UR
The metered values and phasor representations for phase current, ground current, phase
voltage, and auxiliary voltage are displayed via the front panel interface or through the
Plus
EnerVista UR Setup software.
The metered values and phasor representations for negative-sequence current and
voltage, positive-sequence current and voltage, and zero-sequence current and voltage
are displayed via the front panel interface or through the EnerVista UR
