Emergency Generator Testing
Present day machines are subjected to extremely high electrical and mechanical stresses and therefore, have shorter life spans as compared to yesterday's bulky machines. Unfavorable operating conditions may lead to unexpected troubles, which in turn can cause harmful effects on machine life. The insulation system is extremely important and therefore should be checked on a regular basis.
The purpose of the routine maintenance and inspection is to ensure those procedures recommended by equipment manufacturers are discharged in order, and the equipment life and reliability are extended , thus reducing the need for repair.

relates the ability of the generator to carry a load over a period of time. There are three types of load banking available to you systems.
Service factor is the multiplier that is multiplied by the nameplate horsepower. The result is used for temperature testing with continuously applied load until the temperature equilibrium is reached.
Short-time duty is a generator operating at continuous load over a period of time less than that required to reach thermal equilibrium. The short time duty ratings are usually 15, 30 or 60 minutes.
Overload duty is the ability of the generator to continuously carry an overload for an extended period of time.
