LONGMONT — A $1.1 million transformer being trucked from Wisconsin to the city’s new electric substation collided with an overpass in Iowa last Friday, delaying the station’s completion.
“It had a conflict with an overpass. The overpass won,” said Tom Schaeffer, chief electrical engineer for Longmont Power & Com

Diamond Cables, at its meeting held Apr. 23, 2007, approved conversion & renaming of Western Transformers to the name & style `Diamond Power Transformer.` The company had acquired Western Transformers in March 2007.
Large power transformers are used in electric power systems. Industrial and residential large power tranformers that operate at the line frequency (60 Hz in the U.S.), may be single phase or three-phase, and are designed to handle high voltages and currents. Efficient power transmission requires a step-up large power transform
The control power transformer provides control power for the bank as well as a voltage signal for the power factor controller. In most cases the control power transformer is connected phase-to-phase, but in some instances, it may be connected phase-to-ground. 
Most electronic circuits need a DC supply such as a battery to power them and the main supply is AC it has to be converted to DC to be useful in electronics. This is what a power supply transformer does. First the AC mains supply passes through an isolating switch and safety fuse before it enters the power supply transformer
