Three phase power transformer secondaries that are set up in a delta configuration do not have an earthing or grounding point. By contrast, a wye configuration of windings would provide such a point, ...

Grounding problems and unwanted noise in electrical ... In this case, it was non-ideal capacitance in the transformer. According to the model, this power supply could be improved by adding a ...

Applications for grounding grids include pipelines, substations, transformers, large motors, computer stations, and high-voltage power lines. They are often used with lighting protection. Grounding ...

They can also be used to isolate, suppress harmonics, derive neutrals through a zig-zag grounding arrangement, and reregulate voltage. Their electrical characteristics are as follows (see Tables ...
