Electrical Control Panels
Electrical Control Panels  
The Automatic Mains Failure Control Panels is designed to monitor (& to start Generator automatically) the mains source and upon partial or full failure of the source / Main supply.
When mains fail, then it is sensed by Line Voltage Monitor (L.V.M.) and three starting pulses are given to Genset.
If Genset does not start within three attempts, then ‘Starting Failure’ alarm is sounded and stop signal is given to Genset to stop it fully & no start signals are given further.
If Genset starts within three attempts, then remaining starting pulses are automatically cut-off.
When Genset starts successfully, it builds up the rated voltage and Genset contactor/breaker is closed automatically. The load then is switched on / transferred to the Genset.
When Mains restores, which is checked by L.V.M. for its healthiness, the generator is then disconnected from the load and automatic transfer back to the mains source takes place, with the generator running on a cool down period and resetting ready for next failure. Load is now connected to the mains.

Genset is then run for about 5 minutes time set, on no load and it is stopped automatically.
The cycle can be repeated if Mains fail again
Safeties like L.L.O.P., H.W.T. and over speed (optional) are operative when the Genset is
Running. For any of the above faults, Genset stops immediately.
Additional safeties can be added, if it is a specific requirement of the customer.
Automatic function can be totally by-passed and Genset can be started-stopped in manual mode also.
While the load is connected to Mains, the Genset can be tested for its performance in TEST mode also. In TEST mode, the total automatic cycle can be tested, without closing the Genset breaker.
