ActiveHigh-voltage test techniques—Very-fast-front overvoltage measurements
高电压试验技术 特快波前过电压测量
Application Summary AI generated
This standard specifies measurement methods and performance requirements for very-fast-front overvoltage (VFFO) phenomena, typically arising from gas-insulated switchgear (GIS) disconnector operations. It is applied in high-voltage power equipment testing and laboratory environments to ensure accurate characterization of steep-front voltage transients. The standard is critical for assessing insulation coordination and equipment reliability in ultra-high-voltage (UHV) transmission systems.
