Power Transformer Testing and Maintenance


No moving parts - no need for maintenance, right? Unfortunately, for many companies the truth is a rude shock. Transformers are a critical part of any power distribution system. If they go down, everything they feed is out of service, sometimes for months. This seminar covers the primary types of tests used for maintenance and diagnostics, including insulation power factor, winding resistance, excitation current, ratio testing, and an overview of dc tests for dry-type and small transformers. Also covered will be factory tests, expected results, and their significance. 

This book is now available in PDF format only.
