Power factor testing of Sulfr hexafluoride circuit breakers - Siemens USA

At the time of production, sf 6 gas circuit breakers are subject to a high-voltage withstand test. This incorporates an AC High-Potential (Hi-Pot) test transformer capable of achieving the required high-voltage levels (per industry standards). Therefore, field Hi-Pot testing is also not necessary or required.

IEC 62271-200 - HV Switchgear And Controlgear

High-Voltage Switchgear and ControlgearRetrospectiveOverview of IEC 62271-200Part 200:AC metal-enclosed switchgear and controlgear for rated voltages above 1 kV and up to and including 52 kV Switchgearsare important nodal points in modern power distribution. Correspondingly important is their reliable functioning, a clearly defined switching behavior according to specified parameters as well as the protection of personnel and protection against operational interruptions when an overload occurs. The International Electrotechnical Commission (IEC) has taken up the task of developing the required specifications, their worldwide standardization and further development. The same applies to IEC 62271-200– the new standard for medium-voltage switchgear.
