GE DEH-233 Entellisys System Test Kit

• Simulates power line characteristics for a single circuit breaker in the Entellisys Low Voltage System
• Verifies the function/operation of the protection system
• Overcurrent Protection Tests – Long Time, Short Time, Instantaneous and Ground Fault Protection Tests
• 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
• Saves test results to be reviewed later
• Windows Interface for ease of use
• Operation from 120 Vac

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
