T/CEEIA 816-2024 Photovoltaic/wind power generation transformer energy efficiency level
T/CEEIA 816-2024 Photovoltaic/wind power generation transformer energy efficiency level
Basic Information
Scope
Scope: This document specifies the terms and definitions, energy efficiency grades, loss level codes, technical requirements, and test methods for transformers used in photovoltaic power generation and wind power generation, and provides an estimation method for the annual operating costs of transformers used in photovoltaic power generation and wind power generation. This document applies to three-phase transformers with a nominal system voltage of 10 kV and 35 kV, a rated capacity of 16,000 kVA or less, without no-load voltage regulation, with a core material of electrical steel and amorphous alloy, and a rated frequency of 50 Hz, for oil-immersed transformers and dry-type transformers used in photovoltaic/wind power generation. Other transformers used in new energy power generation and transformers used in energy storage can refer to this document for use. This document does not apply to inflatable transformers, tower transformers, and cabin transformers.
