When considering a transformer replacement, a few tips can ensure a quick return to service, reduced costs and less downtime, according to an article on the Healthcare Construction + Operations website.
It's important to select the right kind of transformer. For instance, for indoor applications, dry-type transformers are the most common — in part because they are air-cooled, so they pose lower risk of problematic leakage, environmental issues and fire.
It's also important to evaluate the winding design. A round coil design provides significant ongoing operational and cost-saving advantages.
In addition to the design, the material used for the windings and insulation. While copper does have a higher upfront cost, it more than makes up for that by outperforming and outlasting aluminum, the article said.
