Abstract
This paper is intended to analyse the protection and behaviour of fault on power transformer in different operation conditions. For protecting three-phase power transformers of more than 5 MVA rated capacity and operating at voltages exceeding 10 kV. In some cases, a user may apply the techniques described in this guide for protecting transformers of less than 5 MVA ratings or operating at voltages less than 10 kV. This provides information about protection and using proper relays and other devices to protect transformers used in transmission and distribution systems in this guide. General philosophy, practical applications, and economic considerations involved in power transformer protection are discussed. Emphasis is placed on practical applications.
