EETI has established domestic advanced high voltage and large capacity testing laboratory, and can provide clients with product certification testing, quality supervision and inspection, commissioned test and technical evaluation testing service for high-voltage switchgear and control gear.

In the high voltage electrical testing field, EETI, for the very first time in China, has adopted high current test power source with a measurement and control system combined with several groups of large capacity impulse generators and 220kV grade high-voltage test special lines, which can meet large capacity electrical power source required by carrying out 35kV, 220kV and 550kV, 1200kV(under building) and various levels of high-voltage electrical short circuit tests. This testing system has the advantage of flexibly adjusting test voltage and testing current according to the requirement of tested products. Also EETI can meet the test requirements of a wide variety of different client groups, and greatly shorten test cycles and improve the efficiency of providing test reports.
