How do you megger a motor
WebInterpreting test results. Insulation resistance readings should be considered relative. They can be quite different for one motor or machine tested three days in a row, yet it does not mean bad insulation. What matters is the trend in readings over a longer period, showing lessening resistance and warning of coming problems. WebScore: 4.1/5 (30 votes) . Megger testing measures resistance between the phase windings of the motor under test and ground.If there is an insulation breakdown, the resistance is …
