Home / As high-voltage switchgear integrated relay protection device
High voltage (HV) switchgear is a combination of electrical disconnects, fuses, circuit breakers, and relays designed to monitor, control, and protect high-voltage circuits. This tool gives a quick guidance to find a SIPROTEC 5 protection relay which would fit your needs. To ensure a microcomputer integrated protection device correctly and accurately performs its relay protection tasks, selection during design should comprehensively consider reliability, response time, maintenance and commissioning, and additional functions. A big difference between conventional electromechanical and static relays is how the relays are wired. They are used in a wide range of applications, from transmission and distribution to industrial power systems. The MultilinTM 850 relay is a member of the Multilin 8 Series protective relay platform designed for the management, protection and control of feeder applications.
