Q. How do you calculate the insulation resistance of transformer and what is the minimum value?
Ans. The insulation resistance of the transformer will be calculated by using Megger and the minimum value of insulation resistance is 50 mega Ohm's.
Determine the value of Resistance: Determine the value of R, so that the condition for resonance is fulfilled Figure Solution Admittance of first branch
