Power-Frequency Partial Discharge Test Equipment/ Lab Equipment


I. Product Introduction & Features:

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.HZJF System 10kVA/100kV composition.

1. Test Control Table/Case 
2. Free Gas type transformer
3. Coupling capacitor   
4. Protective resistor           
5. Isolation filter             
6. Partial discharge detector
7. Other accessories         


Hezhong control Unit and PD-free testing transformer are controlling and voltage boosting for test object which boosted to the rated voltage.
Partial discharge detector is detecting and displaying partial discharge capacity.
Isolation filter is device of anti-interference caused by power supply. 
Coupling Capacitor is transmitting partial discharge signal to partial discharge detector.
