What are the common alarms in diesel generator?
Fuel Oil Pressure Low Fuel Oil Filter Dirty. fuel oil supply pump malfunction. Fuel oil inlet valve throttled or not fully open.
What are the trips in generator?
Generally, a generator trips due to either the circuit breaker disrupting the supply or a problem with the Ground Fault Circuit Interrupter (GFCI) receptacles. Both the circuit breaker and GCFI are used to protect devices from damage, however, they serve slightly different purposes.
What are the common causes of generator failure?
Common Causes of Generator Failure
- Battery Malfunction. There are several things that can cause your battery to fail.
- Fuel, Coolant, or Oil Leaks. Fuel leaks often happen due to an issue with the pump system.
- Low Coolant. Coolant is what keeps your engine from overheating.
- Air in Fuel System.
- Poor Maintenance.
What causes generator overcurrent?
An overcurrent event on a synchronous generator set occurs any time the load demands more current than the nameplate rating of the generator set. The overcurrent can be caused by the starting of a large motor, the inrush associated with the charging of a transformer, a short circuit or any other number of events.
What are the interlocks in main engine?
Main engine interlocks
- Turning gear Interlock. This device prevents the engine from being started if the Turning gear is engaged.
- Running Direction Interlock.
- Starting Air Distributor in end position.
- Main Lube.
- Auxiliary Blower Interlock.
- Air Spring pressure Interlock.
Why does the breaker keep tripping on my generator?
When too many appliances are connected to a generator, more electricity is flowing through the circuit than it can handle, causing it to overload and trip the breaker to protect your devices.
What does under frequency mean on a generator?
Generator frequency is the number of electrical cycles per second, measured in Hertz (Hz) and this is directly proportional to the engine speed. So if the frequency goes down, it is due to the engine speed. If the generator frequency is going down, but the engine speed is constant its a different problem.
Does the alarm of Diesel Generator controller affect the normal operation?
The alarm of diesel generator controller is not the amount of stop alarm, which does not affect the normal operation of diesel generator. When the alarm occurs, the unit will not stop, and when the alarm conditions do not exist, the amount of warning will automatically disappear.
What happens when a generator alarm is activated?
When this alarm is activated, generator will shut down immediately. This alarm too leads to shutdown of the generator immediately. If the generator senses the over speed, it will suddenly reduce the speed and shutdown. This was all from the article on generator alarms and trips.
How do I know if my generator is going bad?
Low fuel level. High engine temperature alarm. High generator winding alarm. Some bigger gensets have vibration sensors with DSP’s monitoring them for any odd vibrations, which could be an early indicator of a problem. Depending on the facility, case, etc., there may be door open security alarms to protect the physical asset from tamper.
How to avoid generator shutdown due to false alarms?
Regularly clean the oil mist detector head for avoiding the false alarms. When this alarm is activated, generator will shut down immediately. This alarm too leads to shutdown of the generator immediately. If the generator senses the over speed, it will suddenly reduce the speed and shutdown.
