تعریف و معنای "megohmmeter"

What is a "megohmmeter"?

A megohmmeter is a tool used to measure the resistance of electrical insulation in cables, motors, or other electrical components. It applies a high voltage to the insulation and measures how much resistance is present, helping to identify any deterioration or faults in the insulation material. Megohmmeters are commonly used in electrical maintenance and testing to ensure that insulation is intact and safe, preventing potential electrical shorts or failures. The tool provides readings in megohms, indicating the effectiveness of the insulation in preventing current leakage.
