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

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 ...

All questions and answers are based on the 2011 NEC. Q. When is the neutral considered to be a current-carrying conductor for the purposes of ampacity adjustment? A. There are a couple of cases when ...

This whitepaper compares single phase and three phase circuits from the component count, stress level and complexity standpoints. The document shows that on most cases, single phase circuits are the ...

Fort McCoy’s Directorate of Public Works (DPW) and Xcel Energy continued to work together to finish the process of changing the electrical grid on post from a Delta Electrical System to a Wye ...
