SEG WI LINE CT powered protection relays

All relays from this Woodward's WI Line 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. 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
