As shown in figure "B" of the illustration, what is the appropriate action to take? See illustration EL-0044.
The motor should be meggered more often as the result of the 2010 megger reading.
No concern should be given, as the motor winding insulation resistance reading is still acceptable even based on the 2010 result.
Preparations should be made either to refurbish or replace the motor in question based on the 2010 result.
Another 5 years of service life can be anticipated prior to having to refurbish or replace the motor based on the 2010 result.
