INTRODUCTION
1.1 GENERAL
The electrical power distribution system is designed to supply electric energy as
economically as possible, with an acceptable degree of reliability and quality. In a power
distribution system, the distribution transformer is the most important apparatus. The role of
the transformer begins at generating station as the power is generated at the maximum value of
11 VK at generating stations in India and is far away from the load centers. This power
needs stepping up to extra high voltages for reduction of current and subsequent losses
during transmission.
