Key Functions

Intelligent Terminal key functions
Function Capabilities
Electrical monitoring Monitor voltage, current, and power on phases A, B, and C in real time. Record when the main circuit is energized and de-energized. Display voltage and current trends.
Closing status Display operating characteristic curves and operating times for the trip coil, closing coil, and spring-charging motor.
Temperature and humidity monitoring Monitor closing-coil and busbar temperatures. Monitor temperature and humidity in the primary and secondary compartments.
Mechanical characteristics Display the trip-coil rotation angle in real time and convert it to a travel value. Display trip-coil characteristic curves and opening and closing speeds.
Historical records Select and review stored opening and closing operation records. Select record files from different times and operating states.
