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 ...
Q: The percent impedance of a transformer is also the voltage drop of the transformer at full load. What is the voltage drop of a transformer at various other load levels, i.e. 25%, 50%, 75% or in ...
Distribution transformers must adhere to NEC and NFPA 70 standards, with specific requirements for overcurrent protection, ...
In numerous equipment, a switch-mode power supply (SMPS) delivers various output voltages, each powering different sections. With the introduction of low-voltage circuits such as DSPs, it's not ...
This Power Tip shows you how to do a quick conversion of parallel-to-series complex impedances (and vice versa). It also shows that a graphical representation of this transformation as a function of ...
