    What do you need to know to calculate Transformer Voltage

    The Transformer Voltage Calculator enables users to identify transformer primary and secondary output voltages through its turn ratio calculations. The tool determines step-up or step-down output voltages through primary voltage and primary and secondary winding turn inputs. When calculating secondary voltage, you need to multiply primary voltage by a ratio between the secondary winding number of turns and the primary winding number of turns (VSecondary = VPrimary × (NSecondary / NPrimary)). Electrical engineers join students and technicians who find this calculator necessary for their transformer work in power distribution as well as electronics and circuit design. The tool shortens complex calculations for transformers and voltage checks to provide electrical applications with improved efficiency and precise results.

    Conversion using the Transformer Voltage Calculation Formula

    The formula to calculate the voltage in a transformer based on the turns ratio is:

    Rearranging the formula to solve for the secondary voltage:

    VSecondary = VPrimary × NSecondaryNPrimary

      Where:

    • VSecondary = Secondary voltage
    • VPrimary = Primary voltage
    • NSecondary = Number of turns in the secondary winding
    • NPrimary = Number of turns in the primary winding
