Abstract
A power plant is required to supply the energy produced by power generators in as stable and efficient method as possible. A circuit breaker is used to connect the generator to the network and to separate the generator from the network. Figure 8.1 shows two different layouts of a power plant. The circuit breaker which connects and disconnects the generators in the power plant is located either at the high-voltage (HV) side of the step-up transformer (HV synchronization of the generator with HV circuit breaker) or at the medium voltage (MV) side between the generator and the step-up transformer (MV synchronization of the generator with MV circuit breaker). In the latter case, the MV circuit breaker is called a generator circuit breaker because special duties and capabilities are required.
