Compressor Stator Vacuum Testing Machine, Stator Testing System
1. Test item and introduction
1.1 Test item: AC Hipot, insulation resistance, surge, DC
resistance and rotation
1.2 Features: original negative pressure technology, vacuum degree
can be set freely (0~-90KPa). The winding or coil imperfection can
easily be found under the condition of negative pressure.

3. Performance description
3.1 Standard equipped two testing stations. Surge, Hipot, DC
resistance, insulation resistance and rotation can be tested at
one-stop.
3.2 The production efficiency will be highly improved in the
production line.
3.3 All the tests can be selected to test as required and set the
parameters range of pass.
3.4 The alarm will be triggered automatically.
3.5 Test the environment temperature in real-time and convert the
resistance value to that under standard temperature.
3.6 Surge test can set the waveform start and end part, and select
the judge area.
3.7 The surge impulse times can be set.
