This standard specifies the terms and definitions, usage conditions, product models, structural and performance requirements, technical requirements, inspection rules and methods, nameplates, signs, packaging, transportation and storage of dry-type transformers for photovoltaic power generation. This standard is applicable to three-phase non-excitation voltage regulating dry-type transformers (hereinafter referred to as transformers) for photovoltaic power generation with nominal system voltages of 6kV, 10kV, 20kV and 35kV, rated frequency of 50Hz and rated capacity of 100kVA to 2500kVA. Dry-type transformers for photovoltaic power generation with nominal voltage, rated frequency or rated capacity of other systems may refer to this standard. This standard does not apply to gas-filled transformers.
