Last month's Code Calculations article covered transformer calculation definitions and some specifics of delta transformer calculations. This month we turn our attention to the differences between ...

Note: This article is based on the 2020 NEC. A transformer transfers electrical energy (power) from one system to another by induction, with no physical connection between the two systems (other than ...

Using a flyback topology to generate a high voltage is a common approach. The voltage can charge a capacitor for a high-energy pulse. Such an approach is used in defibrillator capacitors, photoflash ...

A bipartisan group of 12 U.S. senators on Jan. 18 introduced a bill that could freeze the Department of Energy’s (DOE’s) implementation of updated energy efficiency standards for distribution ...

Three major electric power trade groups in a letter on Feb. 15 urged the Department of Energy (DOE) to reconsider proposed energy efficiency conservation standards for distribution transformers, ...

PATRICK ROHAN, TERO KALLIOMAA – Although transformers have a high efficiency – typically above 99 percent – the industry-wide energy losses from transformers are significant simply due to the huge ...
