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 ...

Inadequate shielding and bad grounding are often blamed when measurements are inaccurate, especially in high-impedance applications. In fact, shielding and grounding problems are frequently ...

All Code references are based on the 2005 National Electrical Code. The grounding and bonding requirements in this column apply to solidly grounded systems that operate at not more than 600V, such as ...

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 ...

All isolated DC-DC power converters include an input filter, output filter, transformer, primary-side switch(s), secondary-side rectification and a controller. The controller can be referenced to ...
