Selecting overload protection and wires for transformers involves number of rules that change with transformer size, type, and placement of the overload protection. This calculator helps determine the current values on both sides of the transformer, and estimates available short circuit current. Download.
Quickly calculate; Power, Voltage, Current, and Power Factor. Estimate the maximum available short circuit current at transformer terminals.
Enter values using mouse or keyboard in any sequence you like, current for a given power, or vice versa.
Does not require manual. All terms and definitions explained on screen. Built-in Typical Code multipliers. Built-in minimum allowed transformer impedance values.
"Electrical Calculator is a simple, useful and effective application worth having when you need to quickly calculate and estimate available short circuits. Specially intended for electrical engineers and contractors, Electrical Calculator enables you to perform various calculations and determine the values on both sides of the transformer. The application comes with a user-friendly interface and enables you to change the primary voltage and current as you prefer, then quickly view all the generated results." – Softpedia Review
