International technical platforms such as the IEEE PES Transmission & Distribution Conference and Exposition play a key role ...

The use of a copper winding as a temperature sensor is not new. The traditional technique is to disconnect the ac power and the load and to quickly make the measurement using an ohmmeter. But the ...

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

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.

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 ...

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 ...

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 ...
