IHM-6000 Transformer Terminal Unit

IHM-6000 Smart Transformer Terminal Unit (TTU) with measurement functionality is designed based on the advanced measurement and sensor technology. Through modern communication network (FO/4G/3G/GPRS/DSL), it realizes remote monitoring and control related to the Transformer's operations and in real-time condition, as well as data acquisition and data analysis, capturing and reporting abnormal events.

It can monitor transformer running state in real time (voltage, current, power factor, load unbalance, temperature, power…), meanwhile acting as Data Concentrator for gathering metering data from secondary side of transformer. It provides the data necessary to conduct preventive maintenance and proper network planning, ultimately improving the stability of the power supply.

With flexible input and output, Smart TTU can control other IEDs in distribution substation like smart capacitor, streetlight feeder, Ti-switch (for Micro-Grid), smart switch for connection and disconnection of transformer and also receive signals from IEDs.
