Compressor Stator Vacuum Testing Machine, Winding Resistance Tester
1. Stator Vacuum Testing introduction
1.1. How can we check the insulation resistance between enameled
wires?
It can be inspected by the surge test. There are many ways to test
the turn-to-turn insulation of windings, but the voltage impulse
has been widely used in the world. It is featured with simple
circuit and convenient operation. The voltage can be applied to the
stator directly, which makes the test result more precisely.
1.2. Why choose the Stator Vacuum Testing Machine to test surge?
The coil defect of the product is easily to be found in negative
pressure environment. The lower the pressure, the longer the arc
will be caused under same voltage. The working environment of the
compressor stator is very close to vacuum.
