Protective Relay: Working, Types, and Applications
Learn about protective relays, their working principle, types, and applications in power systems. Discover how relays protect transformers, generators, and transmission lines from faults.
Protective Relays
SEL transmission line relays provide high-speed, subcycle line differential and multizone distance protection. Advanced fault-locating features enable rapid crew dispatch and faster service restoration.
AR high speed auxiliary relays
The high threshold design AR is a sensitive high speed auxiliary relay with four normally open contacts, designed to be secure against misoperation due to inadvertent grounding of a station battery or the
Reyrolle High Speed Trip Relay
The 7PG15 trip relay can be used with the Trip Circuit Supervi-sion relay (7PG17, XR250 to XR351) to monitor and supervise the integrity of the trip circuit with coil supervision terminal.
Utility Benchmarking of Fast Trip Schemes and Relay
FS devices are capable of very fast tripping (1/2 cycle or 0.01s). However, these devices have limited load current ratings and fault duty capability (100A and 4kA, respectively), restricting their use to taps
