Selection Guide for Power Transformer
1 Scope
This standard specifies the general principles and relevant requirements for the selection and use of power transformers.
This standard is applicable to guide the rational selection and use of power transformers in power planning and design. When the user chooses a transformer,
You can refer to this standard to determine the type, technical parameters, technical performance, maintenance strategy and contract of the transformer.
