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 ...

Transformers quietly handle one of the most important jobs in the power grid—changing voltage levels so electricity can travel safely. This video explains how coils and magnetic fields work together ...

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 ...

An explosion, a fireball and then darkness: Heathrow Airport uses as much energy as a small city, and when a major fire at a substation caused the power to fail late Thursday, the world learned how ...
