Woodward Protection Relay

Woodward is an independent designer manufacturer and service provider of control solutions for the aerospace and industrial markets.

Woodward protection relay. This highest availability is a key factor for reliable power generation. Our experience with wi line self powered protective relays shows that the mtbf mean time between failures is approx. Simple but safe wiring high electromagnetic in. Woodward protection relays of the wi line are offering time over current protective functions and optional earth fault protective functions in the well proven technique for ct powered protection relays.

As combination of a com pact protection relay and related core type transformer the wic1 system was especially developed for compact. Time over current relay woodward has developed specifically for such requirements. The voltage protection relay mru4 provides precise and reliable protective functions and is very easy to operate. Woodward s intelligent generator protection relays provide a broad scope of primary and backup protective functions from overcurrent protection to generator differential protection.

The wib1 is a ct powered protection relay with minimal space requirement which complies with the highest demands on a digital protection device. With isolated star point or earth fault compensation er xr relay type two step protection for the residual voltage for applications where only individual protection functions are required woodward can of course also offer the following mr relays as individual devices. High tech line is a compact protection relay designed for modular housing structures based on 19 systems. It is designed to protect electrical equipment from dangerous voltage fluctuations.

For example protection against under voltages caused by mains shortcircuits or overvoltages due to load shedding or failure of a generator voltage.
