Answers
Explanation :- the insulation resistance of a transformer winding can be easily measured with help of megger . The megger is the instrument uses for measuring the resistance of the insulation. The resistance of the insulation is high , the pointer of moving coil deflects towards infinity and if the resistance of insulation is low , the pointer of moving coil deflects towards zero. The accuracy of megger is so high as compared to other instruments . That's why answer is megger .
