In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management.

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 ...

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 ...

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 ...

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.

Transformers are static electrical devices with no moving parts, transforming electrical power from one voltage and current setting to another. The frequency of the electrical current remains constant ...
