GB/T 20993-2012
ActiveDC filter capacitors and neutral bus surge capacitors for HVDC transmission system
高压直流输电系统用直流滤波电容器及中性母线冲击电容器
Application Summary AI generated
This standard specifies technical requirements, test methods, and acceptance criteria for DC filter capacitors and neutral bus surge capacitors used in high-voltage direct current (HVDC) transmission systems. It applies to capacitors designed to suppress harmonic currents and protect neutral bus components from voltage surges in converter stations and HVDC substations. The standard ensures reliability and performance in power transmission projects, particularly for long-distance or cross-border HVDC links.
