Application:
It is mainly used for testing frequency voltage insulation level of various insulation materials, insulation structure and electrical products, also as partial discharge frequency testing power supply for testing object such as transformer, mutual inductor and lightning arresters. It widely used in electrical manufacturing, power operation departments, research institutes and universities.
The system includes:
1. Test Console
2. PD free oil/gas type transformer
3. Coupling capacitor
4. Protective resistor
5. Isolation filter
6. Partial discharge detector
7. Other accessories
Features:
- 320*240 LCD screen,high speed thermal printer.
- HV Voltage, LV voltage, LC current measured at the same time, with high precision sensor and high performance collection chip
- Automatic mode and manual mode for option.
- Display HV voltage, LV voltage, LV current, time and withstanding result.
- Over-voltage and over-current protection. Output voltage, HV current upper limit, LV current upper limit and timing can be set.
- Zero-starting function. Test can be proceed after the voltage is back to zero.
- Store up to 8000pcs data in 3months. It has USB port to upload data to USB disk.
- When setting voltage is arrived, it will timing automatically. After timing, voltage will be back to zero.
- When the LV current is over setting value, the voltage will be cut off automatically and it will be back to zero. When the HV current is over setting value, the test object will be cut off and test can be proceed continuously.
- With anti-interference ability, suitable for electromagnetic environment.
- With wheels for both control unit and HV unit, easy to move.
