About This Product

■Protective device

This is a microprocessor type device that quickly and accurately detects failures in power system transmission lines and distribution lines, and quickly isolates faulty sections from healthy systems. This device is part of a system that supports the all-digitalization of unmanned power distribution substations, and has primary and secondary protection for one bank of transformers, as well as protection and reclosing functions for six feeders. Additionally, a new data save function has been added for feeder accident analysis. variable protection unit

■Variable primary protection element

・51P (Overcurrent relay: Stage time limit detection) ・51PI (Overcurrent relay: Instantaneous detection) ・67G (ground fault direction relay) ・64VP (ground fault overvoltage relay) ・51G (ground fault overcurrent relay)

■Variable secondary protection element

・64BP (Blind spot ground fault relay) ・51S (Overcurrent relay: Stage time limit detection) ・64B (Ground fault overvoltage relay) ・64VS (earth fault overvoltage relay: for earth indication) ・27 (Undervoltage relay) Distribution line protection unit

■Distribution line side protection elements

・51F (Overcurrent relay: Stage time limit detection) ・67GF (ground fault direction relay) ・51GF (Ground fault overcurrent relay) ・64VF (ground fault overcurrent relay) ・79 (Reclosing relay)

■Systematic phenomenon analysis device

In addition to saving data of analog input waveforms during system faults, it also collects transient waveforms during intermittent ground faults and records various phenomena during high resistance grounding that does not lead to self-destruction.
