ALL OF THE ABOVE MEASUREMENTS WILL BE CONFIGURED IN THE LOCAL CONTROL PANEL PLC FOR ALARM AND SHUTDOWN AT PRECONFIGURED PARAMETERS

Vibration Monitoring System

A Vibration Monitoring System will be fitted to the generator and configured to the protection panel for emergency shutdown in the event of out of parameter vibration

Bearing Temperature Monitoring System

A Main and Large End Bearing Monitoring System will be fitted to detect early signs of any bearing failure. This will be configured to the panel for emergency shutdown in the event of excessive temperatures being recorded.

Mechanical Protection & Associated Systems

Overspeed governor operates the pneumatic trip valve, which releases the fuel-purge system.
Lubricating oil pressure low, or loss of control air pressure.
( Pressure trip operates pneumatic trip valve. Racks move to “ zero fuel” position.)
Alternator is protected by a microswitch operated by the fuel pump control shafts.
