1. Test: AC Hipot, Insulation resistance, surge, winding resistance
2. Fixture: customized fixture device to adapt the different tested stator
3. Technical parameters
| AC Hipot:apply AC high voltage from the silicon steel sheet to iron core, and test the current of testing loop. | |
| Output voltage setting range/ precision | AC 200～3000V ±(2%×setting value+10V) |
| breakdown current testing range/precision | 0.10～20.00mA ±(2%×display value+0.05mA) |
| breakdown current presetting alarm range | Max:0.10～20.00mA；Min:0.00～20.00mA |
| test time range/resolution | 0.5～999.9s 0.1s/step |
| arc detection | 1～9 (9 is the most sensitive level) |
| Insulation resistance:apply DC high voltage between winding and iron core and check the insulation resistance of testing loop. | |
| output voltage setting range/precision | DC 500V/1000V ±(2%×setting value+10V) |
| insulation resistance testing range/precision | 1～500MΩ ≤100MΩ:±(3%×display value+0.5MΩ)； >100MΩ:±(5%×display value+5MΩ) |
| insulation resistance alarm setting range | Max:0～500MΩ；Min:1～500MΩ |
| test time range/resolution | 0.5～999.9s 0.1s/step |
| Surge:apply impulse high voltage to windings, and compare the oscillation graph with the saved graph. | |
| output voltage setting range/precision | 500～3000V ±(3%×display value+8V) |
| sampling frequency | 100MHz |
| Surge graph comparison | Area, area difference, corona, phase. Three surge graphs will be displayed on the test interface |
| DC winding resistance:four-wire resistance measuring method. Apply DC current to the windings and test the temperature and winding resistance under current environment. The resistance will be converted to the value under designated temperature(generally 20℃ or 25℃) automatically. | |
| measuring range and precision | 10.0mΩ～20KΩ ±(0.3%×display value+3 words) temperature compensation can be set |
| test time range/resolution | 0.5～999s 0.1s/step |
| temperature compensation | Yes |
| temperature probe/measuring range | DS18b20 -10.0℃～+50.0℃ |
| precision | ±0.5℃(range:-10℃～+50℃) |
