When alternating current (AC) prevailed over direct current (DC) in the late 1800s, one of the deciding factors was the need for voltage levels to be raised and lowered throughout the power system to ...

Matz Ohlen and Peter Werelius of Megger discuss the unique method of winding resistance measurements in transformers and how they are a fundamental importance to detecting potential mechanical and ...

By technology, the global dry type transformer market is segmented into cast resin and vacuum impregnated (VPI) dry type transformers. In a cast resin transformer, the live part consisting of the core ...

In the field of electrical engineering, a power system is made up of several pieces of equipment and one of them is a transformer which is the most crucial part of the whole system, the same as a ...

A popular electrical component used on many control circuits is the step-down transformer. It is the power source for a separate lower-voltage circuit which typically controls the operation of a ...

The Electrical Apparatus Service Association (EASA) recently announced the publication of an update to AR200, now titled the “Guide for The Repair of Dry-Type Transformers.” This guide outlines best ...

For serious high-voltage plasma, you need a serious transformer. [Jay Bowles] from Plasma Channel is taking his projects to the next level, so he built a beefy 6000:1 flyback transformer. [Jay] first ...
