High Voltage Capacitor test
Ensure the following requirements have been met before starting the test:
•
The appliance has been disconnected from the power supply and protective measures have been taken to ensure
the power cannot be switched on again.
•
The appliance is cool.
•
The high voltage capacitors are discharged before commencing work.
•
Anti-static precautions have been taken.
•
The casing of the appliance has been removed.
•
High voltages and large currents are present at the high voltage capacitor.
•
It is very dangerous to work near this part when the oven is on.
•
NEVER make any voltage measurements at the high voltage circuits, including the magnetron filament.
1.
Remove all electric connections from the high voltage capacitor.
2.
Using a Digital Multi-Meter (DMM), check for continuity:
Results should be as follows:
•
Connect the DMM to both terminals of the high voltage capacitor.
•
The test is passed if the DMM display reaches approx.
10 MΩ.
•
Connect the DMM to one terminal and the metal outer case of the
high voltage capacitor.
•
The test is passed if the DMM display reads "open circuit".
•
Repeat the test for the other terminal and the metal outer case.
•
Using the DMM, test the insulation resistance between both
terminals and the metal outer case of the high voltage capacitor.
•
The test is passed if the megger display reads over 100 M
Ω
