  Transformer protection - Some typical equipments for protecting a transformer  There are different types of transformers: two-winding or three-coil power transformers, autotransformers, tuning transformers, grounding transformers, rectifying transformers, etc.   It is common practice to provide relay protection by Buchholz for all transformers 0.5 MVA and above. For all small  distribution transformers , only the high voltage fuse is used as the primary protection device. For all larger nominal and critical distribution transformers, overcurrent protection together with limited earth fault protection applies.   Below are some transformer faults that commonly happen. We also have transformer protection device to prevent transformers for these faults.    Table of contents:    1. Stresses generated by the supply source-protection of transforme r  2. Stress due to load 3. Overload and internal fault of the dry type transformer- t...
