Web24 de feb. de 2012 · Only measuring insulation resistance by megger may not always give the reliable result. As the resistive value of an electrical insulator may also vary with temperature. This difficulty is partially solved by introducing polarity index test or in short PI value test.We will discuss the philosophy behind PI test, below. When we apply a … WebA megger is an electrical measuring instrument, it can be used to measure the insulation resistance. A megger has a DC generator and an ohmmeter in it. A normal ohm meter cannot be used to measure high resistance values, so in that case, we can use a megger or megohmmeter. With the help of a megger, we can measure the electrical leakage of a ...
