Abstract
A method for measuring a negative terminal insulation resistance R, present between a negative terminal of an energized electrical apparatus and a ground ideally isolated from the energized electrical apparatus, and a positive terminal insulation resistance R, present between a positive terminal of the energized electrical apparatus and the aforesaid ground ideally isolated from the energized electrical apparatus. A first switching circuit is arranged between the positive terminal and ground, thus in parallel with the positive terminal insulation resistance R, and arranging a second switching circuit between said negative terminal and ground, thus in parallel with the negative terminal insulation resistance (R).
