Как измерять сопротивление изоляции мегаомметром?

A brief overview of how to properly measure the insulation resistance of an asynchronous motor with an induction megohmmeter. When using a megohmmeter, a high voltage of up to 2500 V is applied to the circuit under test. In an induction device, a built-in electromechanical inductor with a manual drive, operating on the dynamo principle, is used to generate test voltages. A megohmmeter is designed to measure the insulation resistance of power cables and the interwinding resistance of transformers and electric motors. 00:00 What is it? 00:47 Megohmmeter scale switching modes. 01:36 Applied voltage selector. 02:24 How to connect the probes to a megohmmeter? 04:18 Measuring the insulation resistance of an electric motor 07:48 Bathing a gray electric motor...
