ActiveOn-site inspections method of a.c.circuit systems for 220 kV substations on plateau
高原220kV变电站交流回路系统现场检验方法
Application Summary AI generated
This standard specifies the technical requirements and procedures for on-site inspection of AC circuit systems in 220 kV substations located in plateau regions. It is applied during the commissioning, acceptance, and maintenance phases of high-altitude substations to ensure the accuracy and safety of current transformer, voltage transformer, and secondary circuit connections under low-pressure and low-temperature conditions. The standard is critical for electrical engineers and testing personnel working on power infrastructure in high-altitude areas such as the Qinghai-Tibet Plateau.
