In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management.

It’s impossible to balance line-to-line voltages perfectly in three-phase circuits, so they typically differ by a few volts or more. However, if voltage unbalance exceeds 1%, it can markedly decrease ...

A three-phase power meter is more than a few DMMs and some duct tape. Portable power analyzers are not a one-size-fits-all commodity product. They come in many different shapes and sizes with a wide ...

In the original version of this article, the second figure contained an error. The image has been updated. It’s important for engineers to have a good, working ...
