Electrical network test system HVGTU

for switchgearfor cablesdistribution transformer

This Series incorporates the most advanced SF6 gas application technique, with features of safety assurance, accident prevention, and inspection maintenance. Ⅰ Introduction The system is especially designed for testing GIS in the factory and on-site test, and for testing all GIS switchgears and GIS components such as insulators, insulating tension pole, GIS PT etc. It also can test transformers, power cables. As its good encapsulation, it can perform PD test in normal environment. When it tests partial discharge, the PD level is less than 3pc, and it can be added a HV bushing to perform the withstand voltage test at the same time. Ⅱ Features 1.The equipment is small and available with minimal space 2.Components are light in weight 3. Rugged structure capable of handling long distance transportation 4. Direct connection with the subject 5. All high voltage parts are encapsulated in airtight space to ensure high safety of operators 6.Wide range applications, adding installation bushings can do normal withstand voltage testing. 7.Built in high voltage measurement and PD coupling capacitor 8.Built in high voltage isolating switch, which can separate interface of multiple test products, to ensure safety of high voltage test. Ⅲ Basic configuration 1.HVGTU High Voltage test transformer 2.High voltage Coupling capacitor 3.High voltage measuring capacitor 4.Current limiting reactor 5.Voltage regulator 6. Isolated transformer 7. Compensation reactor 8. Console
