Instrument Transformers

1. Introduction, 2. Studies on Current Transformer, 3. Studies on Capacitive Voltage Transformer, 4. Data on Electrical System

Existing instrument transformer technologies as well as new measuring principles for current and voltage measurement are described in this book. The properties of conventional current and voltage transformer as well as the dimensioning are discussed in details out of the long experience of the authors. Especially the dielectric dimensioning and the used materials are discussed. Beside this an overview over new modern measuring principles is given and the technology of low-power instrument transformer, and RC-dividers are shown.

This book provides a comprehensive resource on technical, application and operational aspects of all types of electrical transformers and power systems, covering operation theory; transformer construction, installation, operation and maintenance; principal transformer connections; transformer types; troubleshooting; circuit breakers; disconnecting devices; fuses; lightning or surge arrestors; protective relays; storage batteries; reactors; capacitors; rectifiers; instruments; and insulation. Illustrations and diagrams are included throughout the written presentation.
