WI Line-Family WI LINE CT powered protection relays

Product Description

Tripping characteristics range from two-stage, independent (DEFT) and dependent (INV) time-overcurrent protection, up to special characteristic curves. As further options, we offer some relays with integrated earth fault protection. Woodward has also developed serial products, which match nearly any circuit breaker commonly available on the market. The electronic parts of the relays are completely sealed in. This makes the relays resistant to even the very worst environmental influences.

All WI Line devices are self-powered time overcurrent relays, which means they take their energy from the current transformers. Since they do not require auxilliary power, the WI Line relays are well suited for use in self-sustaining transfer and distribution stations, local grids, and ring-main-units.
