Last year’s hurricane season brought devastating destruction to Puerto Rico, Houston, the Caribbean, and the Southeastern United States, leaving homes flooded, supplies limited, and widespread power outages. The average hurricane season produces 12 named storms with 6 becoming hurricanes, so we need to be prepared each and every year. Here at Corefficient, we understand [...]

In a step-lapped miter core, the core steel is miter cut and step stacked in groups of 5 -7 laminations at a time. In this arrangement, the grain orientation of the core steel lines up with the direction of the flux, which then flows parallel with the direction of the grain orientation. Four main [...]

The magnetic flux distribution in the transformer core, and particularly at the joints, has a considerable influence on efficiency losses. This is the reason why Step Lap Full Miter (SLFM) stack core designs superseded designs which use rectangular joints. Also this new arrangement, in particular yokes with "V" notches for the center leg, allows for [...]

There is a new challenge for the Transformer Industry in 2016: The US Department of Energy (DOE) has determined that higher transformer energy efficiency standards will result in significant conservation of energy. With new amendments to existing standards, electrical losses are expected to drop by about 8 percent for liquid-immersed transformers, 13 percent for [...]
