Home / 110kV Single Power Supply Line Relay Protection
The 110 and 220 kV lines of the main grid are protected by means of two primary protection schemes (two distance relays or a distance and a differential line relay) or a primary protection relay (distance relay) and a backup protection relay . 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'). The equipment manufactured shal for trouble free operation of the equipment specified in this specif acturing shall be such that. As part of its mandate to meet the increasing electricity demands of Ulaanbaatar while ensuring uninterrupted, reliable, and high-quality energy supply, the National Power Transmission Grid (NPTG) takes on the responsibility of expanding, revamping, and maintaining power transmission.
