WebApr 21, 2024 · Megger Working It uses three testing voltage like 500V, 1000V or 2500V. A hand-driven generator. It is used to generate the desired voltage. The generator supplies a constant voltage. The voltage can be used for the measurement of low resistance. It has a total of three coils. WebMegger: It is a measuring instrument used for the measurement of the insulation resistance of an electrical system. As the open-circuit has very high resistance, so the megger will so infinite resistance. Meggar does not need any controlling torque.
WebThe megger is a portable instrument used to measure insulation resistance. The megger consists of a hand-driven DC generator and a direct reading ohm meter. A simplified circuit diagram of the instrument is shown in below Figure. The moving element of the ohm meter consists of two coils, A and B, which are rigidly mounted to a pivoted central ... WebHence in a megger, controlling torque is provided by coil. How is controlling torque provided in Pmmc instruments? Control – In PMMC instrument the controlling torque is because of the springs.
