Electrical Insulation for Rotating Machines: Design, Evaluation, Aging, Testing, and Repair

A single comprehensive resource for the design, application, testing, and maintenance of rotating machines

Filling a long-standing gap in the field, Electrical Insulation for Rotating Machines covers, in one useful volume, all aspects of the design, deterioration, testing, and repair of the electrical insulation used in motors and generators. Lucidly written by leading experts, this authoritative reference provides both historical background important to understanding machine insulation design and the most up-to-date information on new machines and how to select insulation systems for them.

Coverage includes such key topics as:

• Types of rotating machines, windings, and rotor and stator winding construction
• Evaluating insulation materials and systems
• Stator winding and rotor winding insulation systems in current use
• Failure mechanisms and repair
• Testing and monitoring
• Maintenance strategies

Detailing over 30 different rotor and stator winding failure processes and reviewing almost 25 different tests and monitors used to assess winding insulation condition, Electrical Insulation for Rotating Machines will help machine users avoid unnecessary machine failures, reduce maintenance costs, and inspire greater confidence in the design of future machines.
