Transformer Calculator: A user-friendly app for Current and Voltage Calculations. Current Calculations • Calculate primary and secondary full-load currents. • Determine the turns ratio and transformer type. How it works: 1. Select the phase type (1Φ or 3Φ). 2. Input transformer ratings (VA/kVA) and primary/secondary voltages. Outputs: • Primary full-load current • Secondary full-load current • Turns Ratio: N1 / N2 = V1 / V2 = I2/ I1 Voltage Calculations How it works: 1. Enter Number of turns in the primary and secondary windings 2. Input Primary voltage Outputs: • Secondary voltage • Turns Ratio: N1 / N2 = V1 / V2 = I2/ I1 Effortless and Accurate: Perfect for engineers and students to compute transformer parameters precisely.
Lead Wire Ampacity

Verdict
The clearest difference is in-app purchases: Lead Wire Ampacity at none against Transformer Calculator.'s 1. Lead Wire Ampacity also leads on ads (none vs shown). On price, device support and iOS requirement there is nothing between them.
