The use of a copper winding as a temperature sensor for transformer windings is not new. But the circuit presented here goes further. It can make the measurement in-circuit and in real time. The use ...

This test set uniquely combines winding resistance measurement, transformer turns ratio, tap changer dynamic resistance, core demagnetization, transformer type detection, magnetic balance, short ...

Remember back…way back, to linear power supplies. Heavy transformers. Big capacitors. As part of my EDN CDEL build, I’ve decided to use just such a power supply as the front end to the two DC-DC PSU ...

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 ...

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 ...

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.

A transformer transfers electrical energy from one system to another by induction. Except for grounding and bonding connections, there’s no physical connection between the two systems. For this reason ...
