I Have total load current 20amps in each phase i have 3phase cunnection i want to instal a generator so will u advise me what should be the capicty of generator.
Dear Mr. ANSARI ;
to be able to calculate the Generator's power, we should know :
– Rhe Voltage's value between 2 phases.
once knowing, we apply the following formula :
S = 1.73 x U x I
where :
– S : generator's Power in ” VA “
– U : voltage between 2 phases
– I : line's current
but after calculation we should add at least 20-25 %, because the bigest effeicency for a generator done at 75-80% of his power.
Regards.
