Insulation Resistance Testing

Testing the resistance of a motor’s insulation system with a megohmeter

(megger) ensures that the motor is not internally shorted, which can

cause damage and/or injury. Check the pump’s maintenance manual

for recommended testing intervals.

6

Megger Test motor

Set your Megger Tester to 2X the motor’s

rated voltage (250V in this instance), and

attach the testers red lead to one of the plug

spades, and the testers black lead to the

ground prong. Press the TEST button on the

Megger and record readings after 20

seconds. Repeat test with the other plug

spade to ground.

Resistance values between 20 MΩand 1 MΩ

indicate that the insulation system is starting

to fail. Readings under 1 MΩafter 20

seconds indicate a shorted motor, and the

unit cannot be economically repaired.

If any reading is less than 20 MΩ, test motor

and cable separately to isolate the problem

to either the cable or the motor.

If the problem is in the cable, replace cable

and re-test. If MOTOR resistance is less than

1 MΩ, there is evidence that the motor is

damaged, and the motor should not be

used. Further disassembly and inspection

will be necessary.

7

Cable Inspection

Measure and inspect pump cable. Note total

length of cable. Cables, as supplied, are 20’

in length (older units are 32’).

If there are any cuts or other deformities in

the cable, or the cable is less than 20’ in

length, the cable should be replaced.

Inspect cable plug for damage and ensure

that grounding prong is intact for safe

operation.

Cable Assembly

Removal

Using an 8mm socket or Phillips screwdriver,

remove the two bolts securing the cable

gland to the head cover.

CAUTION: If water has worked it’s way into

the motor area, this can be under pressure

and water can spray out. Wear eye

protection.

Carefully wiggle the cable assembly out of

the motor casing and inspect the

connections. If there is oil and/or water

present in this area, the motor assembly will

need to be disassembled for inspection and

repair.

Disconnect the three bullet connectors that

connect the cable to the motor stator and set

cable aside.
