Overcurrent Relay

Overcurrent Relay

The SEL-351, a directional overcurrent relay, features four-shot reclosing and fault locating while offering the latest innovations in high-accuracy metering, system frequency measurement, system monitoring and setting flexibility. The relay measures nominal voltage and current to within à›ª.1 percent accuracy, power to within à›ª.5 percent accuracy and voltage/current phase angles to within 0.5 degrees. The distribution and transmission relay provides directional overcurrent elements, fault locating and under and overfrequency protection at all voltage levels. The relay can be used in a broad variety of protection applications for radical and looped transmission or distribution systems.
