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 ...

Cooper Power Systems has designed its full-featured differential relay, the iXP-420, to provide comprehensive two-winding transformer protection, and monitoring and control. The iXP-420 incorporates ...

Beckwith Electric's Transformer Protection System M-3311A provides protection, control, monitoring and user interface functions for two, three or four-winding transformers. The system includes ...

Those readers who have experimented with winding their own inductors will know that it’s not an easy task, and when those inductors are handling high voltages it can be especially tricky to maintain ...

This application note presents the application and specification of signal transformers. It also describes the basics of wideband transformers and autotransformers, and its design equations. This ...

A thorough understanding of Delta and Wye service transformers, their primary and secondary windings, and their windings’ voltages, will help HVACR service technicians in their understanding of ...

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 ...

This symbol has been the logo for my LinkedIn group, Analog Developments. The image is of a single transformer winding that I needed to make whose turns were arranged on the bobbin as two pi-sections.
