I.Introduction

• YD-Series High-voltage Testing Transformer uses advanced production equipment, and new technology of coil winding epoxy vacuum pouring and CD-type iron core, which obviously reduce weight and volume, improve insulating strength and humidity resistance level, effectively weaken leakage magnet resulting in greatly enhance the ability to withstanding impact of testing short circuit current of transformer.

• This series products have features of light weight, small volume, beautiful appearance, stable performance, convenient usage and carrying, especially suitable for site operation, are new generation high voltage testing transformer used for AC and DC in China. 

• This series products are applicable to power system and all power users to detect on site the insulating performance test of all electrical equipment, high voltage power sources of all appliance's voltage system or equipment with DC high voltage small current.

 

Main Functions

 

1.The Hipot tester is composed by the test transformer and voltage control unit.

 

2.The tester is applied in insulation test of power equipment and insulation materials in power frequency.

 

3.Hipot tester is low cost and easy to operation.

 

4.That makes the tester is widely applied in insulation test whose test voltage and capacity are not high
