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.

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)
