Standards relevant to transformers – Part V: Transformer selection and application
In this part of the series, national standards available for the selection and application of transformers are summarised.
byP. Ramachandran
In the previous four parts of this column, we have explained the evolution of transformer standards by IEC, IEEE, EN, plus technical brochures by CIGRE bodies. We have also noted the current standards available on transformer specifications.
In this part of the series, national standards available for the selection and application of transformers are summarised. Numbers in the bracket next to the standard number indicates the previous edition of the particular standard.
Currently active national standards are important for the transformer design, manufacturing and operation – they reflect today’s transformer technology
IEC 60076-8 Transformer application guide provides users with information on selection and characteristics of three phase transformer connections, zero sequence impedance characteristics, tapping selection and features, operational issues (parallel operation and fault currents) and measurement accuracy of losses.
The authors hope that this comprehensive list of various national standards covering various aspects in the selection and application of transformers will be useful for consultants, users and designers of transformers.
