Prüfung der Motorwicklung mit einem Megohmmeter


Explanation:
Perhaps there is a shorter way of expressing it, but this is what is meant.


1.Is There Any Way to Prevent Three Phase Motors from Burning Up?
No, but there is a preventative maintenance method that can reduce motor burn-outs. This method is referred to as "meggering a motor." Meggering a motor checks the condition of the motor windings insulation. Failure of the insulation on the motor windings is what causes motor burn-out.

A "megger" is a megohmmeter; that is, a meter that measures electrical resistance in millions of ohms. This meter is used to check insulation on motor windings by surcharging the windings with 500 to 1000 volts, and measures the leakage to the motor case. This is very similar to checking water pipes for leakage by pressurizing the pipe system and timing pressure loss.

2. Wenn der Motor längere Zeit gelagert wurde oder ungünstigen Feuchtigkeitsbedingungen ausgesetzt war, muss der Isolationswiderstand der Statorwicklung mit einem Megohmmeter oder einem Isolationsmessgerät geprüft werden.
