In Topic: Var Compensator

Thanks the post was most helpful.

I would rep+ you if I knew how but one more question I looked around when I googled VAR compensators is there any difference between a

A Static VAR Compensator and a Adaptive VAR Compensator? or is adaptive VAR compensators just a brand for static var compensator?

thanks marke. i have the 3 motors and only just got 1 datasheet for one of them but it had the info i was looking for

load %, power factor, efficiency graph

sad thing is for the other 2 motors... the manufacs won't send me the data sheet. they say they will but never sent... T__T so lame.

Thanks for replying

ok but here's the thing these motors are 150kw 250kw and 400kw (rated power) no way i can just stick an oscilloscope and measure them...

what's the best way to get the pf of each motor? an estimate would be good enough. i know their rated power, rated v and current. and rpm. i have their brand, frame, made.

This mag current (that is independent of the load) you speak of can i get that from the data sheet? (dont have the measure?)

so after i get that, I go COS(ASIN(mag current/loaded current))?
