TABELA DE GERADORES

These calculators will assit you in determining what size generator you may require or how to convert one unit of electricity to another.

They 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


Calculating Ampere (I), given kVA.

Converting kVA to kW   Converting kW to kVA
kVA = kW   kW = kVA
 


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


Generator Size to Start Motors

Instructions: You only need to fill in the columns coloured in blue.
Fill in 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)
