Transformer Calculator

Transformer Calculator — Calculate Power, Current, Voltage, and Efficiency

Calculate transformer parameters including power ratings, current, voltage, efficiency, and winding specifications for your electrical projects.

Step 1: Transformer Specifications

Power Rating (kVA)

10 kVA

Primary Voltage (V)

Transformer Basics

Transformers transfer electrical energy between circuits through electromagnetic induction. The voltage ratio equals the turns ratio between primary and secondary windings.

Step 2: Efficiency & Load

Efficiency (%)

95%

Load Percentage (%)

80%

Efficiency Considerations

Transformer efficiency depends on core material, winding design, and load. Higher efficiency transformers have lower losses (copper and iron losses) but may cost more.

Basic Transformer Equations

V_p/V_s = N_p/N_s = I_s/I_p

Power (VA) = V × I, Efficiency = (Output Power / Input Power) × 100%

Power Loss = Input Power – Output Power
