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 ...

Have you ever wondered why some low-voltage (115-V) power-consuming devices burn out too often? It could be because they are wired to a “high” or “wild” power leg of a voltage supply. These devices ...

A full wave rectifier circuit is fed from a transformer having a center-tapped secondary winding. The rms voltage from either end of secondary to center tap is 30V. If the diode forward resistance is ...

Transformers are very reliable devices and can provide service for a long time if regularly maintained and serviced. They’re also the single most costly item in any substation. To protect against ...

Tap changers are devices that can increase or decrease the output secondary voltage by changing the turn ratio of primary or secondary winding. A tap changer is usually installed on a high voltage ...
