I’m sure many readers would question why anyone would want to perform a relatively expensive insulation power factor test on an inexpensive transformer. Typically, if any testing is done, it will be ...

Testing is crucial for ensuring the reliability of transformers in power grids. While their electrical function may seem simple, transformers are actually complex machines that require careful design, ...

The mains of the world were constructed as a giant copper causeway to transport electricity from the generating station to our homes and factories. Today's problems on the mains were unknown a few ...

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 ...

Through much of the developed world, we have come to rely on a steady flow of electricity just as we have a steady flow of air. Power outages are still disruptive, but they are few in number, and we ...

An emergency spare transformer program is a key part of the preparation for and rapid recovery from a high-impact, low-frequency (HILF) event, the Department of Homeland Security (DHS) said this week ...

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 ...
