Impact Analysis of Power Quality Problems of Transformers

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.
