Web25 nov. 2003 · 6.The One-Megohm Rule, I am going to quote out of a book featuring Megger Insulation Testing.It is called a "Stitch in Time". Quote: Insulation resistance should be approximately one megohm for each 1000 volts of operating voltage with a minimum value of one megohm. For example, a motor rated at 2400 volts should have a minimum … Web5 jan. 2013 · above, the minimum insulation resistance is kV+1. For a 460. volt winding the minimum, using the former “kV+1” rule, would be 0.46 + 1 = 1.46 megohms, whereas the minimum. is now five megohms. Note that all of these minimum values are based on a. winding temperature of 40 °C.
