  • Single Point Relay Protection Tests (Overvoltage, Undervoltage, Over Frequency, Under Frequency, Power Reversal and Phase Loss, High Current Test)
  • Verifies the calibration of the trip time current curve
  • Verifies the operation of the circuit breaker actuation in “Trip mode”
  • Performs tests without trips in “No Trip mode”
  • Ground Fault Defeat function provides temporarily suspension of all Ground Fault protection in the system
  • Automatically retrieves system configuration for increased productivity
  • Displays a summary of all protection configuration

The test kit Interface with the system is through the EntelliGuard™ Messenger protection unit. The interface consists of 7 analog and several digital channels representing actual power line characteristics. The signals are injected directly into the Messenger A/D converters. This tests the entire Entellisys System, excluding the CTs, the CT interface (burden resistors) inside the Messenger, and the PTs
