The dc generator in megger can generate EMFs ranging from ____ to ______ depending on the instrument.
Right Answer is:
50V to 500V
The dc generator can generate EMFs ranging from 200 V to 1000 V, depending on the instrument.
The Megger has two main elements, a magnet-type de generator to supply current for making measurements, and an ohmmeter that measures the resistance value. The generator armature is turned by a hand crank usually through step-up gears, to produce an output voltage of 500 V. When the crank is turned, the gears turn the generator at high speed to generate an output voltage that may be 100, 50, 1000, 2500 or 5000 V, depending on the model.
