 Usage：
The series impulse voltage generator is used in the impulse voltage testing of lightning impulse full wave, lightning impulse breakdown wave and switching impulse wave. It can also be used to check the insulation property of power equipment. 

Performance： 
The 50-1200kV non-partial discharge power-frequency testing transformers have passed the appraisal of two-ministries. The soiiage transformer has obtained the national practical patent. The factory is the unique one to manufacture the sustaining transformer. They are mostly used in sino-foreign joint venture power transformer manufacturers (shanghai- Aistom for example). Main technique capabilities are domestic-leading and keep ahead in the world. 

Characteristics: 
1、Integrated whole set equipments and voltage cases 
2、There is a lower induction in the impulse voltage generator circuit and the band rejecting measurement is used. The result is that the standard impulse wave can be generated in despite of the big capacitance load exist. The equipment is unique iniand, and is used in many companies. 
3、High voltage utilization ratio. The utilization ratio of lightning impulse wave is higher than 90%. and that of switching impulse wave is higher than 80%.
4、The generator has the compact structure, fine appearance, simple operation, fine synchronous property and reliable action. 
5、The silicon controlling and LC constant current charging auto-controlling technology is used. There are high automatic and strong noise-proof property. 
6、The electronic delay adjustable circuit or L-C delay measurement is used in breakdown wave time delay. 
7、The computer-controlling (optical fibre) system is the unique one to be registered by national copyright administration, and reaches the GB/T and TEC standard.
