Many older industrial facilities use single-phase, oil-filled transformers made for pole-mounting but installed at ground level to create 3-phase power distribution systems. Usually, primary and ...

Do you believe that volt/VAR optimization based on single-phase capacitor bank switching (rather than three-phase switching) that minimizes both energy consumption and feeder voltage balancing index ...

The article in the March 3 issue of The News dealt with the secondary windings of a Delta service transformer with one winding center-tapped to the ground. The article stated that the power-leg or ...
