Overvoltage
Injects a phase voltage greater than the set point for the specified time delay. There are three
options:
•
One phase is above the pickup threshold
•
Two phases are above the pickup threshold
•
Three phases are above the pickup threshold
Undervoltage
Injects a phase voltage less than the set point for the specified time delay. There are three
options:
•
One phase is below the pickup threshold
•
Two phases are below the pickup threshold
•
Three phases are below the pickup threshold
Phase Loss
Injects a negative-phase-sequence voltage greater or less than the nominal 1X value of the
system voltage.
Power Reversal
Injects waveforms that have the direction of the power reversed and the magnitude of the
power greater than the set point for the specified time delay.
High Current Alarm
Injects waveforms that have currents greater than the programmed threshold for a time
greater than the programmed delay to generate high current alarm.
NOTE: For the High Current Alarm test only, the test kit will not be able to provide any Test
Results because the test kit does not receive any feedback from the Messenger. To verify the
results, the operator must check for a High Current Alarm event in the Entellisys HMI, Sequence
of Events screen.
Two test methods are provided for Relay Protection:
•
Pre-Defined Test – uses pre-defined fault levels for the test selected.
•
User-Defined – allows the operator to set fault levels for the test selected.
