Three elements are consolidated as one.
Protection
Use
Measurement
◆It is the best for the digitalization of the receiving /
distributing power system that replaces conventional protection
relay and the meter.
Features
◆A high economy is achieved by consolidating the measurement,
protection, and the control.
◆The installation space can be reduced, and the board be
miniaturized.
◆Display of measurement value and digitalization of set value
◆The installation space can be reduced without unnecessary
transducer board.
◆History display function of various failure data of accident
◆Reduction at downtime by enhancement of self-diagnosis function
◆The control source available for AC/DC.
