Electrical Power Calculators

The following calculators are provided to help you determine the size of generator required for your specific application. Other calculators on this page are for unit conversions and other power related calculations.

Guide to Standard Uints
Kilo Volt Amperes	kVA
KiloWatts (1000 watts = 1 kW)	kW
Ampere (Volt-Amperes or Current)	I
Volts	E
Power Factor	PE
Percent Efficiency	%EFF
Horse Power	HP

Power Requirement Calculator

Phase	Volts Required V	Amperes I	Power Factor	=	Power kW
1 3			.8 1.0

Converting kW to kVA

kW	=	kVA

Converting kVA to kW

kVA	=	kW

Converting kW to HP

kW	=	HP

What size genset is needed to start a 3 phase electric
motor Direct on Line (DOL) start

HP of Motor	=	Generator kVA Required

Calculating Amperes (when you know kVA)

Phase 1,2,3	Generator kVA	Volts Required	=	Ampere I
