The history of Shanghai Power Transmission & Distribution Testing Center Co., Ltd. (called SETC) can be traced the Central Laboratory including High Power and High Voltage Laboratories founded in 1957 which was qualified by four ministries of Chinese Government to perform the tests of High/Low Voltage switchgearand issue type test report.

   After reformation and reconstruction to increase the test capabilities, SETC as a third-party laboratory was accredited by China National Accreditation Service for Conformity Assessment(CNAS).

   There are 5 departments that are 220kV Circuit, 35kV Circuit, High-voltage Testing, Quality Control and Management Departments. Both special 220kV transmission line and 35kV cable from a near substation with short-circuit capacity of 15000MVA at bus provide test power source to SETC.

    High Voltage Switchgear and control equipment standard has listed Electromagnetic Compatibility (EMC) test as a controlled pilot of the type test. Accordingly, an electromagnetic compatibility (EMC) laboratory in our center has been under construction. Completion is expected by the end of 2007, which can test equipment in its electromagnetic environment's ability to work normally without causing other equipment that allowed the electromagnetic environment harassment.

    EMC standards laboratories, including 3M Semi-Anechoic Chamber and the necessary test chamber for electronic equipment on the launch of the space to the county or radiation interference (EMC. CE/RE) and the Immunity (EMC, CS/RS) measurement functions according to the corresponding standards.
