Home / Maintenance Regulations for 220kV Relay Protection Devices
Establish a Protection System Maintenance Program (PSMP) as identified in PRC-005. 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'). APPROACH EPRl's Nuclear Maintenance Applications Center reviewed protective relay types and specific applications of these components in power generating station protective schemes, especially those schemes used in nuclear power plants. Protection systems play a key role in ensuring the safe and reliable operation of the entire electrical grid including generation, transmission, and distribution for utility and industrial applications. Protective relays are your most powerful defense against long, costly outages and extensive.
The relay performance during the commissioning is tested using ISA Automatic 3-phase protective relay test set, Digital Relay Test System (DRTS-6) . The fault current and fault voltage injection system
