1.1 Insulation resistance
The table shows suggested values of insulation resistance
and the test voltage in relation to the rated voltage of the
motor.
If the rated motor voltage is ≤ 500 V, the insulation
resistance must be measured at a test voltage of 500 VDC.
If the rated motor voltage is > 500 V, the insulation
resistance must be measured at a test voltage of 1000
VDC.
Note
The insulation resistance must be measured
in accordance with local regulations.
Rated voltage: ≤ 500 [V] > 500 [V]
Condition of motor and cable [MΩ][MΩ]
New motor (without submersible drop cable)  200  200
Used motor which can be reinstalled in well  10  10
New motor in well  20  20
Motor in good condition in well  0.5  1
Damaged insulation < 0.5 < 1
