A transformer calculator determines voltage, current, power, and turns ratio for step-up or step-down systems. It analyzes load capacity, efficiency, and winding needs, ensuring accurate sizing, ...

Transformer sizing ensures electrical transformers are properly matched to load demand, primary voltage, and secondary voltage. Correct sizing enhances efficiency, prevents overload, and ensures ...

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 ...

A transformer transfers electrical energy from one system to another by induction. Except for grounding and bonding connections, there’s no physical connection between the two systems. For this reason ...

Abstract: A new approach to modeling of auto-transformers is presented in this paper. An auto-transformer, compared to a separate-winding transformer, is characterized by small impedances, which can ...

Unlike the voltage transformer, a current transformer measures current from one circuit to another, which requires different calculations to create the optimal design. Current transformers measure ...

When comparing the kilovolt-amp demand loading on Southern Company substations with the actual connected transformer nameplate kVA, it was apparent that, on average, the distribution transformers were ...

Abstract: Transformers are equipment designed to operate perfectly at linear loads. Nowadays with wide use of modern technology requirement and industry needs which utilize nonlinear loads, the ...
