Product Introduction
   The voltage transformer is an unnecessary component for GIS switchgear. It can transform high voltage to 100V or lower standard secondary voltage and can be used for protection devices, measuring devices and instruments, and meanwhile,can separate the HV side from operators.
   As a professional SF6 test equipment manufacturer in China, our company always dedicates to development and manufacturing of high voltage test equipment used for directly flange with GIS switchgear. In 2010, our company successfully developed HV test equipment which is used for performing 220kV or below single phase/three-phase voltage transformer type tests, and successfully launched the prototype to the customers in the same year. Presently, It gets a highly praised from customers. In 2011, the company also developed the HV test equipment which is used for performing 550kV or below single phase/three-phase voltage transformer type tests.
 

Product Advantages:
1.Small and compact dimensions resulting in minimum space requirements ;
2.Light-wight components;
3.Rugged construction to withstand long transportation stresses;
4.Direct flanging to the GIS switchgear ;
5.High safety for tester because of encapsulation of all HV parts;
6.Large range of application in conjunction with HV bushing for withstand voltage test;
7.Built-in HV measuring capacitor and coupling capacitor;
8.The PD of the whole equipment can be less than 3pC, which guarantees the accuracy of test ;
9. The equipment can completely perform power-frequency withstand voltage tests, induced over withstand voltage tests, PD tests and exciting characteristics tests.
