Special Circuit Breaker For Generator applications

The worldwide increasing energy demand is covered by conventional as well as by decentralised power plants. Here the decentralised power generation gains more and more in importance. A great part of decentrally generated energy is fed into the medium voltage grid by generators.

The challenge to protect the grid as well as the generator against failures makes generator circuit-breakers essential. Each generator has specific technical characteristics. A suitability analysis of the generator circuit-breaker application is indispensable.
The system-fed fault (A) and the generator-fed fault (B) of a grid need to be reliably interrupted by the generator circuit-breaker.
