A feature of the standard FDB19 is its non-fail safe operation, ideal for primary breaker
installations or those that are unmanned or prone to supply interruption.
In this case, there are three protection schemes per primary breaker
associated to the line, and remembering that if the failure is really in the L line, at least one relay of a protection scheme at both ends of the line must be activated, except for the 50FI relay associated to the fault of the breaker of the L line and to the activation of at least another relay (21, 21N, 67, and 67N).
The amplifier system features front-panel output power adjustment (manual step attenuator) and RF blanking controls, and an AC primary breaker
