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

One of the hidden complications of upgrading grain drying and handling systems is providing enough electricity to power the new larger electric motors. Electric motors that are larger than 15 hp ...

So you just spent three hours removing and replacing a motor that drives the feed to a robotic welder. You connected the leads exactly the way they were before you disconnected them. You properly ...

This solid-state thyristor (SCR) switch circuit is perhaps the simplest means of reversing a 3 phase motor. “Static” is a catch-all term that essentially means without moving (mechanical) contacts ...

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 ...

One of the more popular three-phase electrical services supplied to medium-size commercial buildings is the Wye or Star configuration transformer. The name comes from the transformer’s secondary ...

Keep in mind when reading any article about electrical theory or application that it only scratches the surface of the topic. You can dedicate years of your life to understanding electrical theory and ...

The project is designed to provide low voltage start to induction motors. This is achieved by using star to delta conversion. Star/Delta starters are probably the most common reduced voltage starters ...
