Gas-insulated metal-enclosed circuit-breakers and substations tested at KEMA Labs

Italy, Milan: Switchgears and control gears are crucial nodal points in modern power systems, and it is vital that they work reliably.

However, the facilities equipped with the right expertise and technologies to test them are rare to find. Therefore, Shanghai Sieyuan High Voltage Switchgear Co. Ltd. has performed an extensive testing program at KEMA Labs in Milan, for the certification of their equipment according to the applicable IEC standards 62271-100, 62271-102 and 62271-203. The program includes testing and certification of the 145 kV and 420 kV gas-insulated metal-enclosed circuit-breakers, disconnectors and substations. The type test certificates of short-circuit and switching performance have been already achieved for the circuit-breakers, while the activity on the substations is still in progress. The certification of the substations includes the verification of the dielectric performance, temperature rise performance, short-circuit and switching performance and internal arc performance.

KEMA Labs, a CESI SpA Division, is the world leader for the independent testing, inspection and certification activities in the power industry.
