	What is the voltage of the generator? __________________ The elephant is a funny bird. It flits from bough to bough. It lays its eggs in a rhubarb tree and whistles, like a cow - Spike Milligan.

	3 phase 440 volts

	It is clearly stated in the manual and on the nameplate affixed to said diesel generator set. If you don't have the manual (and cannot find the nameplate) try the manufacturer's website.

	OK. What is 15kVA divided by 440V? __________________ The elephant is a funny bird. It flits from bough to bough. It lays its eggs in a rhubarb tree and whistles, like a cow - Spike Milligan.

	(15*1000)/440 = 34.09

	34.09 of what units? __________________ The elephant is a funny bird. It flits from bough to bough. It lays its eggs in a rhubarb tree and whistles, like a cow - Spike Milligan.

	i think 34.09 Amps. Is it correct?

	Amps. Am i right?

	KVA=1.732x Line Volt x Line Current X Cos Phi 15=1.732X400xIx0.8 I= 15000/1.732x400x0.8 =26 Amps

Guest	#13 Re: full load current calculation 09/23/2009 5:39 PM
	well I think you need to take some course on basic electricity, first you need to know the ohm's law and apply the formula. I = VA/E, for a one phase system I= VA/(!.73X VXPF) three phase system. I = Ampere; VA = Volt-Ampere; V= Volt; PF= Power Factor (0.8 Typically DG) I hope this help you
