About

Transformer Calculator Plus

This utility app calculates key parameters for transformers, including voltage, current, and turns ratio. It helps determine if a transformer is step-up or step-down, essential for power conversion applications.

Highlights
  • Calculate primary and secondary voltage
  • Calculate primary and secondary current
  • Calculate transformer turns ratio
  • Determine step-up or step-down transformer
  • Supports AC voltage calculations

Transformer Calculator calculate any parameter within the transformer equation, including primary and secondary voltage, current, and turns. Transformer Calculations Include: Transformer Turns Ratio – Current and Turns Transformer Turns Ratio – Voltage and Turns Transformer Turns Ratio – Voltage and Current The result will indicate whether the transformer is step-up or step-down. Transformers are primarily used as power converters. The two types—step-up and step-down—operate on the same principle but in opposite directions. A step-up transformer converts a lower AC voltage to a higher voltage, while a step-down transformer reduces a higher AC voltage to a lower level. For example, if a country uses 110 V power, a step-up transformer converts it to 220 V, and a step-down transformer does the reverse. Both work with alternating current (AC). A transformer consists of a soft iron core with two coils wound around it, which are not electrically connected. These coils may be wound on separate limbs of the iron core or placed one over the other. The coil to which the alternating voltage is applied is called the primary coil or primary winding. When an alternating voltage is applied, the resulting alternating current in the primary winding generates a changing magnetic field. This changing field induces an alternating current in the secondary coil. The magnitude of the induced voltage depends on the number of turns in the secondary winding. All transformers have a nameplate rating. It is best to operate them within the voltage limits specified. Using a step-down transformer below its rated limit can support a wide range of applications, but exceeding the specified limit is dangerous and may cause electrical failure. The relationship between voltage, current, and the number of turns in each coil is given by: Vp/Vs = Np/Ns = Is/Ip Where: Vp – Primary voltage Vs – Secondary voltage Np – Primary turns Ns – Secondary turns Ip – Primary current Is – Secondary current Thank you for your support, and please visit nitrio.com for more apps for your iOS devices.
