6.5.1.3 Power Supply Testing

1. Air test the cable insulation for resistance using a Megger tester

between conductors.

—Replace power cable (S) if readings fall below 30 MΩ.

2. Water test the cable insulation for resistance using a water tank.

This testing method may detect minute insulation flaws that the air

test will not.

3. Submerse the cable in a water tank with conductors on both ends

of cable above the water level. After 24 hours, test the cable

insulation using a Megger tester between conductors and metal

container.

—Replace power cable (s) if readings fall below 30 MΩ.

4. Dry capacitor (o) thoroughly before testing.

IMPORTANT: If using heat gun, do not exceed temperatures of

140°F (60°C).

5. Set circuit tester to 100 KΩ at resistance and connect between

both terminals.

—Capacitor can be reused when the test indicator shakes once

and comes back slowly.

—Replace capacitor (o) when the test indicator shakes

continuously and comes back quickly.
