To test Transformer we give HT side 440V to see wheather
that it is producing 17.6V on LT to verify Voltage ratio is
correct or not but when we give the 440V voltage to LT side
then what will happen to HT voltage ?
Answer Posted / manohar mishra
For ratio test, only the change in voltage is to be measureD. If 440 V is fed to LV, HV voltage will go to a HIGH VALUE (11kV) making it difficult to measure. Blowing of fuses do not occur as there is no flow of current.

we have consol make 3 phase servo stabilizer for cnc m/c. while installing the earth neutral voltage is 1.7 volts at stbilizer off condition and when stabilizer get on en voltage reaches 4.8 volts (new earthing is done and neutral is helthy condition all phase to neutral volts 440,442,441 v)why this happen.solution for cause.
