Professional Line Protection Relay
line protection relays provide subcycle line differential and multizone distance protection for a secure, reliable, and high-speed solution. Their fault-locating capabilities allow you to efficiently dispatch line crews to quickly isolate line problems and restore service faster.
Differential Protection Relays
Woodward's digital separate or combined relays provide all common protection functions for low and medium voltage applications, and are designed for DIN rail mounting. Rated voltage and frequency can be set by means of DIP switches; pick-up values and tripping delays via potentiometers. The wide-range power supply for AC and DC make the relays universal. An optionally available interface adapter enables the devices to communicate with your SCADA system.
