20kW Gas Generator is equipped with 4100ZQ Gas engine made by Weifang Power as original power. It is consisted of Marathon, Stamford,Xingnuo three-phase synchronous alternator, and Control Panel made by special manufacturing plant.
The Generator possesses the following automatic monitoring and protective functions:
a) Audio or visual alarm for:
- High oil and water temperature
- Low oil pressure
- Overcurrent
- Short circuit
- Over-speed
- Reverse power
b) Shut-off for:
- Low oil pressure
- Over-speed
- Short circuit
- Over-speed
Reverse power
a) Shut-off for:
- Low oil pressure
- Over-speed
b) Trip for:
- Over-current
- Short circuit
- Reverse power
The generator can not only supply power directly to load but also can be paralleled running.|
