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.
