The costliest piece of equipment in a substation is the Power Transformer. Therefore, a good maintenance program is required to keep these power transformers operating reliable. Over the past few ...

Part 1 of this three-part series laid out an overview of a proposal to create a numerical health index and establish a practical program for power transformer maintenance. Part 2 breaks down each of ...

Effective transformer maintenance depends on dissolved gas analysis. Effective maintenance of liquid-filled transformers begins with prevention of failure by testing transformer oil for unusual ...

Power transformers are often the main source of common-mode noise in isolated switching power converters. Why? Because inside the transformer, the windings on the primary and secondary sides of the ...

It is important for machine design engineers to understand how transformers work so they can design machinery that operates optimally within the proper voltage ranges, as well as select the right ...

The demand for higher efficiency and smaller packages has been the driving force behind advances in switch-mode power-conversion topologies including buck, boost, flyback, forward converters, and ...
