Voltage Transformer Calculator
Calculate the correct voltage transformer size for your electrical project. Determine power requirements, voltage conversion ratios, and transformer specifications based on your application needs.
Step 1: Electrical Requirements
Understanding Load Power
Load power is the total wattage of all devices that will be connected to the transformer. Add up the wattage of all equipment to determine the minimum transformer capacity needed.
Step 2: Transformer Specifications
About Safety Margins
A safety margin ensures your transformer isn’t operating at maximum capacity, which extends its lifespan and improves reliability. Higher margins are recommended for continuous or critical loads.

Transformer Calculation Formula
Transformer Size (VA) = (Load Power / Efficiency) × (1 + Safety Margin)
To calculate transformer size: Divide load power by efficiency percentage, then multiply by (1 + safety margin percentage). For kVA, divide VA by 1000.
Current (A) = Power (W) / Voltage (V)
