Emergency power switch with synchronization
The switching distributor between mains and generator operation is equipped with two circuit breakers. An electric locking system must ensure that no faulty switching can occur. The NA protection prescribed by the energy supplier (e.g. CDMR grid decoupling relay) must act on its own circuit breaker. If the grid does not exist, it must not be possible for energy to be supplied to the public grid. The monthly load test can be done at any time through synchronization and the excess energy is delivered back to the grid.
On the photos a switching with synchronization (with circuit breaker for mains – parallel operation) is visible.
