Can anyone recommend good reference material ie books and/or websites on insulation,insulation resistance testing, etc.
I have the following questions in particular (this applies to testing motors)
1. What percentage variance is acceptable for winding resistance results for the three phases
2. What PI value is deemed acceptable? 2.0?
Most of the motors are 415V motors, with a handful at 3.3kV.
Look forward to comments, answers,etc. thanks.
