—Replace stator (az) if test results fall below 20 MΩ.
Test Stator Continuity
Test continuity between phase wire ends.
—Replace stator if any breaks are found.
Test Wire Resistance
Measure resistance of each phase using Megger tester.
—Replace stator if test results fluctuate more that ±5% of
manufacturer’s specification.
Note: Allow for temperature induced variations in winding
resistance.
Note: Contacts of imbedded thermoprotector can affect test results.
Test results can be affected if performing test with power
cable assembled.
Locked Rotor Current Test
Lock rotor (an) and apply 25% of rated voltage by lock transformer or
regulator.
—Current measurement test results should be similar to rated
current.
Test Oil Chamber Pressure
1. After installing mechanical seal, attach a vacuum pump to oil
housing.
2. Raise negative pressure inside the oil chamber to 60 cmHg (11.6
in.Hg).
IMPORTANT: DO NOT exceed 60 cmHg (11.6 in.Hg).
3. Hold the vacuum position for 10 seconds. The gauge should
remain absolutely stable.
—Replace mechanical seal upon failing vacuum test.
Test Thermal Protection (CTP)
1. Clean the points of the circle thermal protector (CTP).
2. Check the Insulation Resistance between each phase connection
on the protector and ground.
—Not less than 30 M
Ω with 500V Megger.
6.6.3.1 Motor Reassembly
Note: If, upon inspection and testing, a pump component requires
replacement, use only original manufacturer’s replacement
cables complete with anti-wicking block assembly and
certified for submersible use.
Note: Use only new gaskets and o-rings when reassembling pump.
