Megger is used to Measure
A portable device called a megger is used to measure high insulation resistances. The electromagnetic induction theory explains its operation. A permanent magnet D.C. generator provides the electricity needed by a megger. The test voltages are often generated by a hand-driven generator. They are in the range of 500, 1000, or 2500 V.
A moving coil meter serves as the foundation for a megger’s operation. An earth tester, also known as an earth megger, can test the resistance over a range of currents and distances resistance is measured. The insulation resistance of the cables is measured using an insulation merger. Following are the benefits of a megger.
- Electrical Security
- Can Detect Wire Leaks
- Can check the insulation level of any electrical equipment
- Electronic megger used in confined spaces
- They are easy to use & easy to carry
Summary:
A Megger is used to Measure _____?
To measure high insulation resistance, the Megger is used. All semiconductor devices, when reverse biased are examples of High Resistance Materials. The loss of charge method & direct-deflection method are methods to measure High Resistance.
