Home / 220kV Relay Protection Settings
The documents presented should serve as a model to various utilities in preparing similar documents for setting protection relays installed installed at 220kV, 400kV and 765kV EHV and UHV transmission systems. The numerical terminals referred as IED (Intelligent electronic device) contain apart. e in Indian grid on 30th and 31st July 2012, Ministry of Power constituted a 'Task Force on Power System Analysis under Contingencies' in December 2012. Fingrid's application guideline for relay protection presents the operating principles of the relay protection in Fingrid's 110, 220 and 400 kV power networks and the requirements for operation of the protection systems of Fingrid customers (hereinafter referred to as 'customer'). In HV (High Voltage) and MV (Medium Voltage) substations, relay protection safeguards critical assets such as transformers, circuit breakers, and lines.
