Hi,
I have a step down transformer which inputs are connected to RY phase of 3 phase 3 wire system.
The outputs of the transformer are COM, 230v & COM, 115v. If i check the voltage between each COM & Voltage,
the voltages are shown correct, but there is voltage difference between two COM terminals about 55v.
Is it normal? or something wrong with the T/F?
and
I am giving 230 v supply from transformer to Motor Drive which has 3 terminals COM, 230v, GND.
the voltage between GND & COM is showing about 55v, recently the drive gone bad,
is this the cause for that?
Neutral to ground supposed to be below 5v but it is showing 55-60v...
