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 a protection device that uses a digital relay to detect short-circuits that occur between the windings inside a transformer and ground faults caused by dielectric breakdown that occur between the windings and the iron core, and promptly repair the power system. Separate from.

■Protection elements built into the device

・Ratio differential relay (87T). Detects short circuits in transformer windings. ・Overcurrent relay (51P, 51S). Detects short circuits on the primary and secondary sides of transformers. 51P...Primary side, 51S...Secondary side ・Ground fault overcurrent relay (51G). Detects ground faults in transformers. ・Ground fault overvoltage relay (64B). Backup protection in the event of a ground fault. Two units of each element (each phase) are installed to provide a more reliable configuration.
