Protection of Electrical Power Transformers

INTRODUCTION
In most large electrical systems, generators and power transformers are the two most expensive pieces of equipment. In addition to the capital cost of purchase, these two key devices are also the most critical to continuous and reliable operation of the system.
Consider, for example, the main incoming power transformer of a large industrial plant. Failure of that transformer can result in production losses reaching millions of dollars. If the transformer requires repair or...
