At least one of our experts will respond. Want to challenge our Grid Masters for a chance to win? Q: The percent impedance of a transformer is also the voltage drop of the transformer at full load.

All transformers have nameplates, and all manufacturers use the same nomenclature for capacity, ratings, impedance, and other pertinent information. This article focuses on dry- or oil-type ...

alongside the explanation of another use of Guanella transformers: as an impedance transformer. This shows just how flexible transformers are once you can wrap your mind around the theory.

“Back to Basics: Impedance Matching (Part 1)” discusses the use of a transformer as a basic way to match impedance. This article will introduce the L-network, which is a simple inductor ...

We have a step down transformer from the utility company - 15 KV to 480 volt. The nameplate reads "AIC at zero sequence impedance". I know what the AIC is, but what does the zero sequence impedance ...

The common mode current will increase as the primary and secondary transformer voltages increase or when the frequency of the power supply operation increases. The unshielded capacitance offers ...

The term “impedance matching” is rather straightforward. It’s simply making one impedance look like another like matching a load impedance to the source or internal impedance. Impedance ...
