Power frequency test transformer is applied to detect the insulation integrity of various insulation materials and electric products. It can also be used as the power source for PD free power frequency test. We supply FKYDW series partial discharge free power frequency test transformer and CQSB series ultra light test transformer (oil-immersed/dry/air-filled). 

• AC or DC power frequency voltage withstand tests 

• Able to be used as power supply of PD free power frequency tests

• Two series available: FKYDW series PD free test transformer system and CQSB ultra-light test transformer 

FKYDW series PD free test transformer system
