3.20 Dead Zone Protection
3.20.1 Dead Zone Protection Theory
For some wiring arrangement (for example, the circuit breaker is located between the CT and the
line), if a fault occurs between the CT and the circuit breaker, the main protection can operate to
trip circuit breaker quickly, but the fault has not been cleared since the local circuit breaker is
tripped. Here the dead zone protection is needed in order to trip relevant circuit breaker.
This relay provides a one-stage dead zone protection for above mentioned situation. If the circuit
breaker of the protected equipment is opened and the current is greater than the predefined
setting, the dead zone protection will operate.
The following figure shows the logic diagram of the dead zone protection.
