6.3.1.3 Power Supply Testing
Air Test Cable
Air test the cable insulation for resistance using a Megger tester
between conductors.
—Replace power supply cable if readings fall below 30 MΩ.
Water Test Cable
1. Water test the cable insulation for resistance using a water tank.
This testing method may detect minute insulation flaws that air test
will not.
2. Submerse the cable in a water tank with conductors on both ends
of cable above water level. After 24 hours, test cable insulation
using a Megger tester between conductors and metal container.
—Replace power supply cable if readings fall below 30 MΩ.
Test Capacitor
1. Dry capacitor (q) thoroughly before testing.
IMPORTANT: If using heat gun, do not exceed temperatures of
60°C (140°F).
2. Set circuit tester to 100 KΩ at resistance and connect between
both terminals of capacitor.
