Preconfiguration A for generator

Application

The preconfiguration A is designed to be used for protecting generator units which are
grounded through NGR. Typically, it protects a diesel generator set or an embedded
power generation plant. The generator is connected to a busbar system with a truck
circuit breaker.
The IED controls the circuit breaker apparatus. The switching of a NGR is not
governed by the IED. Similarly, the earth switch is considered to be operated
manually. The open, close and undefined status of the circuit breaker, NGR and earth
switch are indicated on the LHMI.
The preconfiguration includes:
