VD4G-50 – the VD4 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 and the generator-fed fault of a grid need to be reliably interrupted by the generator circuit-breaker.
Security:
- Suitability analysis using grid calculation tool
- Optional system study for additional circuit-breakers in grid
- Tested according to the latest edition of generator circuit-breaker standards including the draft of IEC / IEEE 62271-37-013
Reliability:
- System and generator-fed faults tested up to 50 kA
- High TRV withstand capability
- Suitable for an increased DC component and longer arcing times
Efficiency:
- Maintenance-free solution
- Compact solution
- Economical solution
