T/CEEIA 299-2018 Technical Parameters and Requirements for Dry-Type Transformers Used in Photovoltaic Power Generation

Scope

Scope: This standard specifies the terms and definitions, conditions of use, product models, structural and performance requirements, technical requirements, inspection rules and methods, nameplates, markings, packaging, transportation, and storage for dry-type transformers used in photovoltaic power generation. This standard applies to three-phase non-excited voltage-regulating dry-type transformers (hereinafter referred to as transformers) used in photovoltaic power generation with a system nominal voltage of 6 kV, 10 kV, 20 kV, and 35 kV, a rated frequency of 50 Hz, and a rated capacity of 100 kVA to 2,500 kVA. Other photovoltaic dry-type transformers with different system nominal voltages, rated frequencies, or rated capacities may refer to this standard for use. This standard does not apply to gas-insulated transformers.
