Today's emphasis on implementing energy-efficiency programs and limiting peak demand growth is driving renewed interest in an effective method of implementing volt/var control on distribution systems: ...

In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management. Understanding the trade-offs between Delta and Wye connections enables ...

Improper voltage is the one of the greatest causes of failed compressors in three-phase units. We are allowed a 10% deviation over or under the unit nameplate-rated voltage. Most technicians know to ...

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 ...

An overview of the generation and utilization of electrical energy. Covers three-phase circuits, transformers, photovoltaics, batteries, electromechanical energy conversion, and an overview of ...
