T-IED 23kV has total functions for metering, monitoring, control, protection, and interlock, which are needed for substation automation based on IEC61850. It’s available to be various and flexible engineering with high speed PLC functions for the protective functions . For DI/DO point, it’s possible to check more conditions and control output By choosing the expanded structure. T-IED23kV is the next generation power monitoring and protection device to manage the power system much more conveniently by embedding IEC61850 communication, PLC logic and other functions.
