Combined Inspection and PAT Testing
This again is carried out at pre-determined intervals.
For the checking of
electrical safety, one will require a PAT Tester.
There are many PAT Testers
available but the ones with pass/fail indications are quite easy to use.
All one
has to do is plug the appliance into the tester, connect a test lead and press
a button.
The tester will carry out the required tests and indicate whether
the appliance is safe or not.
When a compressor fails short, what happens is that insulation on the wires
has worn off or burned off or broken Very Low Frequency AC Hipots.
This
allows a wire on a motor winding to touch something it should not touch most commonly itself a turn or two further along on the motor winding.
This
results in a "shorted winding" which will stop the compressor immediately
and cause it to heat up and burn internally.
Bad bearings can cause a failed short.
Either the rotor wobbles enough to
contact the stator, resulting in insulation dama
