110 PRODUCT FAMILY

110 Relay Protection Device

110 Relay Protection Device

The GRE110 is a numerical multi-function protection device designed for feeder protection applications in MV networks,drawing on proven technologies developed over more than 100 years,and providing a comprehensive range of protection and control functions. The relay has two protection stages: a low-set overcurrent stage I 0 > and a high-set overcurrent stage I 0. The SIPROTEC 7SL82 offers combined line differential and distance protection, providing a cost-optimized, compact solution for medium-. The protective and control devices can be used in, for example, single and double busbar applications, as well as radial, looped, and meshed grids. 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').
