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

In a 3 phase system there is a centre point. (like the optional neutral in the Wikipedia image). In domestic power this neutral point is normally grounded to earth, giving 3 phases with equal voltage ...

As load densities grow, three-phase power is becoming more and more prevalent in data centers of all shapes and sizes Three-phase AC power is everywhere. Every major power generation and distribution ...

Last month, we saw how you can use vectors to define complex circuits and determine current. This month, we'll show you how to use vector diagrams and some simple math to calculate neutral currents in ...

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 ...
