Medium-sized generator in block connection with a transformer protection application example with standard configuration C and
RET615
In
Figure 8
generator protection is implemented with REG615
generator protection relay. Transformer protection is
implemented with the RET615 transformer differential
protection relay covering the generator in block connection with
a transformer. A single-phase voltage transformer is connected
to the generator neutral for the residual overvoltage protection.
On the terminal side phase-to-earth voltages are connected to
the generator protection relay.
