Dear all,
This is not an answer, actually question.
In one factory, we are dificult to measure resistance,R and
impedance, Z.
What we have is only voltage supply (3phase, 420volt), and
total current flow during maximum usage using clampmeter
(including machinery, lamp, computers, etc...)
We also have info of main transformer step down because it
is in the factory area. Normally they stated value of KVA.
And some factory already install the 'capasitor bank
regulator'
So, how we can calculate the CORRECT VALUE of capasitor
need to install?
I mean, which one is the correct KW, which one is the
correct KVA, and how to calculate existing power factor IF
the factory already have 'capasitor bank regulator'....can
we switsh of the regulator?
