Rated current of generator: rated power (KW)/(1.732*rated voltage (KV)*power factor) = rated current (A)
Now the generator power is 50 KW and the voltage is 400V, the power factor of the generator is usually 0.8, so:
50/(1.732*0.4*0.8)=90A
< p> The rated current of the 22 kW motor is only 40 -50A between them, not to mention that it starts with soft start and reduced current. Depending on the current, there is no problem!To check whether it is a problem with the generator or water pump, first use pliers to check whether the generator output current is consistent with the actual situation. If there is no problem, find a power source and test the water pump to see if it can work normally. What is the current when it works? A comparison will reveal the problem!
A 250 kW generator is required. bajunsh's answereng is incorrect. A 110 kW pump, even if calculated based on 3 times the rated current, requires a generator of more than 250 kW to start, and it must be an ordinary large generator. A. Factory generator, otherwise at least a 300 kW generator is required.
The Ivanfu generator has the greatest capacity to start the engine
