Scope
Scope: This standard specifies the general requirements, test voltage waveform, test voltage, test procedures, and test result evaluation for on-site lightning impulse tests of gas-insulated metal-enclosed switchgear (including GIS and HGIS) with a rated voltage of 72.5 kV and above. GIS and HGIS newly installed parts, expanded parts, and disassembled and repaired parts shall all be tested in accordance with this standard. Tank-type circuit breakers shall refer to this standard for implementation. Main technical content: The lightning impulse withstand test of gas-insulated metal-enclosed switchgear is effective in detecting defects such as abnormal electric field structures and particles on the surface of insulators, and complements the AC withstand voltage test. To effectively and standardly conduct on-site lightning impulse tests of gas-insulated metal-enclosed switchgear with a rated voltage of 72.5 kV and above, this standard is formulated based on relevant standards and specifications and combined with on-site implementation experience.
