Megger Instrument Function
A Megger, often called an insulation tester, is a specialized electronic instrument. Its primary design is for measuring electrical resistance.
Measurement Range
Meggers are specifically designed to measure very high electrical resistances. This typically includes:
- Insulation Resistance: Testing the resistance of electrical insulation in cables, motors, transformers, and other equipment. This is crucial for safety and performance.
- High Resistance Values: Meggers typically operate using high DC voltages (e.g., 500V, 1000V, or higher) to accurately measure resistances in the megaohm (MΩ) and gigaohm (GΩ) range.
While other instruments measure low or medium resistance, the Megger's specific function and high voltage output make it ideal for assessing the integrity of insulation by measuring these high resistance values.
Conclusion
Therefore, a Megger is principally used for the measurement of high resistance.
