Power Utility Replaces Aging Transformers with Customized, Drop-in Units

As aging transformers at generation facilities near end-of-life cycles, a number of potentially dangerous events can come into play when it comes to aging transformers – in addition to untimely power outages and costly repairs.

Because many transformers are exposed to dust and high operating temperatures, over time they incur such problems as clogged air inlets, clogged cooling ducts, and deterioration of winding insulation, all of which can degrade capacity. If a transformer is operating...
