HVHIPOT 10kVA 100kV Automatic Transformer Partial Discharge Free Test System for Arrester(GDYT)

Product Description

GDYT-10kVA-100kV Automatic Transformer Partial Discharge Free Test System for Arrester


General introduction

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.

GDYT System 10kVA/100kV composition

1. Hipot Test Control Table GDYD-10/100        
2. PD-free Gas type transformer YDQW-10/100   
3. Coupling capacitor  TAWF-800pF/100kV        
4. Protective resistor GR100kV             
5. Isolation filter LBQ-10kVA                    
6. Partial discharge detector 
7. Other accessories         

 
Hipot control Unit (GDYD table) and PD-free testing transformer are controlling and voltage boosting for test object which boosted to the rated voltage.
 
Partial discharge detector(GDJF-2008) is detecting and displaying partial discharge capacity.
 
Isolation filter(LBQ) is device of anti-interference caused by power supply.
 
Coupling Capacitor is transmitting partial discharge signal to partial discharge detector.
