兆欧表, 绝缘测试仪
a specialized electrical testing instrument used to measure the resistance or insulation quality of electrical insulation materials, such as wires, cables, motors, and transformers
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.
- The electrician used a megohmmeter to check the insulation resistance of the cables before installation.
