How Much Load Can A 1000 KVA Generator carry
Generators are usually rated in KVA. The KVA rating is the power capacity of the generator. Usually , 1KW=1.25KVA @ 0.8PF, which means that a 1000KVA generator should deliver 800KW of power. The formla is = S (kVA) = P (kW) / PF Now when you overload a generator, a lot of things happen. A lot of current is pulled from the alternator, the alternator coils begin to overheat and the drag on the prime mover increases then what happens is that the speed of prime mover will fall, and the frequency will drop. If the overload is sustained one of three things would happen. The generator engines will go off when the prime mover stalls or the protection circuits would trip to cut-off the load but in the worst-case scenario the coils of the alternator will saturate and overheat then burn up. So, to prevent overload we have to monitor how much current we are pulling from the generator as the current basically represents the load on the generator. This is true because as we k
