Elsco Transformers reports that choosing the right transformer size involves calculating kVA based on voltage and current for ...

Last month's Code Calculations article covered transformer calculation definitions and some specifics of delta transformer calculations. This month we turn our attention to the differences between ...

Current transformers measure current or transfer energy from one circuit to another, so their design requires calculations different from their voltage transformer cousins. The reason for the ...

Power factor correction is a frequently misunderstood topic. Improper techniques can result in over-correction, under-correction, and/or harmonic resonance, so it can be helpful to understand the ...

Using a flyback topology to generate a high voltage is a common approach. The voltage can charge a capacitor for a high-energy pulse. Such an approach is used in defibrillator capacitors, photoflash ...

Let's look at key formulas that are the building blocks for the transfer of electricity: real and reactive power transfer formulas and their basics. The power triangle represents an essential building ...
