Figure 109: Earth switch control logic
The circuit breaker closing is disabled by default, as in case of generator, the closing
of the circuit breaker is done by a special synchronizer device.
The OKPOS output from DCSXSWI defines whether the disconnector or breaker
truck is open (in test position) or closed (in service position). This output, together
with the open earth switch and non-active trip signals, activates the close-enable
signal to the circuit breaker control function block. The open operation for circuit
breaker is always enabled.
Connect the additional signals required for the application for opening
of circuit breaker.
