Contents: 1. Introduction. 2. Studies on current transformer. 3. Studies on capacitive voltage transformer. 4. Data on electrical system.

Voltage and current in the order of Kilo or mega range cannot be measured directly to study their performance or to analyse their quality. The use of converters plays a vital role in bringing down the values to the allowable working limit for smooth, safe and easy control and operations. These converters are called instrument transformers. This book discusses the important aspect of Instrument Transformers current and potential transformers and capacitive voltage transformers with technical data of the electrical systems. The purpose of this book is to serve as a guide to solve the technical problems on Instrument Transformers, which electrical engineers face during their field works.
