Applications - Renewable Energies

Relays from the WI Line are self-powered time overcurrent relays. Self-powered relays take their energy from the current transformers and do not require an auxiliary power supply.

WI Line relays are well suited for use in self-sustaining transfer and distribution stations, local grids, and ring-main-units while matching any circuit breaker commonly available on the market.

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.

The electronic parts of the relays are completely sealed in. This makes the relays resistant to even the very worst environmental influences.
