Download this article in PDF format. If you search the internet for “transformer equivalent circuits,” you’ll get five pages of over 100 small circuit diagrams. Figures 1 and 2 show two typical ...

Voltage transformers (VT) are used in electrical grids for metering and/or protection purposes. The high requirements regarding their precision demand a calibration ...

I see techs in the field get the most frustrated when they have a low-voltage short they can’t seem to locate. The challenge techs face with low voltage diagnosis is a combination of poor process and ...

In this Design Idea, we explore several ways to use SPICE [1-3] circuit analysis software to determine the Thevenin and Norton equivalent circuit parameters of linear active networks. The Thevenin ...
