 Analyzing and Applying Current Transformers
Current transformers (CTs) are used throughout the world as current transducers for protective relays in industrial, commercial, and utility applications. Standard ratings and application guides deal with the steady-state sine wave behavior of current transformers. Despite the use of recommended rules applied to avoid transient saturation, it always occurs in certain critical relay applications. This book presents transformer concepts that provide the fundamentals to understand the non-linear characteristics, accuracy ratings, and transient behavior of current transformers.

AC Motor Protection
AC Motor Protection presents a unique challenge to the facility, maintenance, and protection engineers. Comprehensive motor protection requires knowledge of all the characteristics of the motor in operation. AC motors, induction or synchronous, require electrical, mechanical, and thermal models to determine the motor characteristics to provide optimized thermal and fault protection. Written for the professional engineer, all of the steps necessary to develop this vital information are included in this concise 90-page handbook.
