Figure 7.
Medium-sized generator protection application example with standard configuration C and D
In
Figure 7
protection is implemented with two REG615
generator protection relays. One REG615 takes care of the
generator protection with 100% stator earth-fault protection
and the other REG615 provides the generator differential
protection.
Standard configuration D is not designed for using all the
available functionality content in one relay at the same time.
Three-phase directional overcurrent protection, three-phase
voltage protection, positive-sequence and negative-sequence
voltage protection functions must be added with the
Application Configuration tool. In order to ensure the
performance of the relay, the user specific configuration load is
verified with the Application Configuration tool in PCM600.
