Prevent Transformer Shutdown

Power transformers seldom shutdown; however, if a shutdown occurs, the effects would be immediate and devastating to utility operations. According to “An Analysis of Transformer Failures” by William H. Bartley, P.E., on behalf of the Hartford Steam Boiler Inspection and Insurance Company, the...

Power Transformers Health Check

Power transformers are static electric machines used to step-up or step-down voltage in electric power applications. The capital cost of a power transformer in the range of 100MVA can be $1M or more and by the time it is under operation, the price is increased. The average age of installed large...

Advancements in Dissolved Gas Analysis: Accounting for Gas Loss

Dissolved gas analysis (DGA) in transformers is a very successful periodic screening method to identify transformers that may be having problems. It is a symptom-based assessment of health, rather than a condition-based assessment. That is because the gases themselves do not cause failure, but are...

Why event-based fault type identification is better than a sample-by-sample approach

Introduction Fault type identification is an important step in dissolved gas analysis (DGA). When a significant amount fault gas production is detected in a transformer, we want to know what kind of physical condition could be responsible for the gassing. Knowing the type of fault can help to...

Transformer Core Grounds

Transformer core grounds: a different path to maintaining insulation systems

BY JAMES WHITE, Shermco Industries, Inc.

Power transformers are usually supplied with a ground from the core of the transformer to the tank (earth/ground). Smaller, dry-type transformers may not have this ground, but it is always used on larger transformers. Grounding a transformer’s core may not sound like a smart thing to do, but it is a very necessary part of the transformer’s...
