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

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 ...

The article in the March 3 issue of The News dealt with the secondary windings of a Delta service transformer with one winding center-tapped to the ground. The article stated that the power-leg or ...
