# Calculator

## calculator

These calculators will assist you in determining what size generator you may require or how to convert one unit of electricity to another.
Please note: All calculations are using 0.8 power factor.

 These calculators will calculate: Amperes when kVA is known Converting kVA to kW Converting kW to kVA Converting kW to HP kVA Required to run motors Guide to units: HP = Horsepower kW = Kilo Watts kVA = Kilo Volt Amps I = Ampere or Current V = Volts PF = Power Factor

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

 kVA = kW

 kW = kVA

 kW = HP

 HP of motor = Generator kVA required

 Instructions: Add a number in the blue column below. Enter the HP of the motor(s) in their starting squence, select the start method (Direct On Line or Star Delta) and press Evaluate. The required generator size will then be displayed at the bottom. 3 Phase (415 volt @ 50Hz) 1 Phase (240 volt @ 50Hz)

 Starting Sequence Motor HP Start Method DOL / StarDelta Run Variable Phase Current Starting Value Total Run Current Total Start Current 1 / 2 / 3 / 4 / 5 / 6 / Generator Size for Starting with: kVA* Generator Size for Running with: kVA* Generator Size Recommended: kVA*
