What does a Megger typically measure?

• A. Capacitance
• B. Induction
• C. Voltage
• D. Resistance

Answer: (D)

A Megger is specifically designed to measure resistance, particularly insulation resistance. It is used to test the quality of insulation in electric wiring and equipment to ensure that it is safe and functioning properly. When a Megger is used, it applies a high voltage to the insulation, and the resulting current flow is measured to determine the insulation's resistance value. High resistance values indicate good insulation, while low values can indicate potential failures or degradation in the insulation material. In contrast, capacitance is measured using a capacitance meter, while induction typically refers to inductance, which is measured with an inductance meter. Voltage measurements are performed with a multimeter or a voltmeter. Each of these other measurement types serves different purposes within electrical testing, but the unique function of a Megger is its focus on assessing resistance, making it a vital tool for ensuring electrical safety and reliability.
