The paper gives a brief overview of electric power system and role of power transformers. The faults in transformers and their protections will be briefly discussed. The damages caused by the occurrence of fault due to some abnormal conditions resulting in consequential severe damages. The root cause of the damage is normally established by conducting various tests at low voltage.  A special case will be discussed when due to extensive damages to the transformer; it is not possible to conduct low voltage tests. The paper will explain as to how the cause of damage is established by very minute study of the type and extent of damages.
