Listing changes AppTracker has observed for this app in this storefront — new versions, price moves, rating shifts, and store copy.
This update focuses on clearer results and more reliable equipment checks. • Redesigned results — see Nominal Current and Short Circuit Current (bolt fault) in amperes, with the formulas used and a detailed impedance breakdown • Fixed fault current calculation — bolted-fault values now match the percent-impedance method used in the field • Improved equipment verification — breaker and fuse interrupting ratings are compared against available fault current; frame and ampacity ratings use a 125% nominal load margin • Clearer guidance in the equipment section so you know what each rating is checked against Save & load, ampacity tables, optional iCloud sync, and Spanish localization are unchanged.

About
Substation Short Circuit helps electrical engineers and technicians estimate available fault current before specifying equipment. Enter system voltage, transformer kVA and impedance, cable length and size, fault type, and X/R ratio. With one tap, get: • Symmetrical fault current • Asymmetrical fault current • Peak current • Interrupting rating • Base current and total cable-system impedance Then check the equipment. Compare circuit breaker current and interrupting ratings, fuse ratings, and cable ampacity against the calculation. The app flags equipment as adequate or inadequate so you can identify potential issues before specifying gear. Need conductor data for the same job? Browse the built-in ampacity table for copper and aluminum conductors, common insulation types, temperature settings, and free-air or raceway conditions. View resistance and reactance, then copy conductor details when needed. Save calculations with a description, search saved jobs later, and load them back into the calculator. Optional iCloud sync keeps saved calculations available across your Apple devices. Built for the field and office: • English and Spanish • iPhone and iPad • Light and Dark appearance • No ads Substation Short Circuit is a calculation aid and is not a substitute for a licensed short-circuit study, applicable codes, manufacturer data, or professional engineering judgment.
