Depending on the type of release, inverse-time-delay overload releases are also available with optional characteristic curves. The nominal pickup point where a circuit breaker trip unit detects an overload is at 1.075 times the selected ampere rating. After the circuit breaker has picked up, it will not trip until the delay determined by the long-time delay adjustment has been achieved.

  • Sizing a MV generator circuit breaker (GCB) in terms of

    Introduction to Gcb CircuitsBreaking Capacity of A GcbProtection Relays For GeneratorsGenerator Protection FundamentalsThe basic design of the generator circuit configuration is displayed in Figure 1. Generator circuit-breakers (GCB) are essentially located between the generator and the step-up transformer of the high voltage network. In generator circuits two different faults are possible with a combination of high short-circuit current at high asymmetrical components: 1. The system-source fault (fault on generator side, point A) and 2. on system-source fault (fault on the transformer side, point B). This is in contrast to the values of the short-circuit current under conditions according IEC 62271-100, which is 25 % of the rated short circuit current. If a system-source fault occurs, the short-circuit current is established at high magnitudes and the breaker is located close to the generator. The energy of the system feeds the fault from the system through the transformer.
