Amps at High Voltage Calculator

Software Version:

Convert low voltage kVA and amps to the high voltage side of a transformer.

Information

How to use the calculator

1. Input the phases to phase voltage, for both high voltage and low voltage.
2. Input the low voltage current. This will calculate the power and high voltage current.
3. Alternatively, input the low voltage power. This will calculate the low voltage and high voltage current.
4. Alternatively, input the high voltage current. This will calculate the power and low voltage current.

Equations

• LV_Amps = (HV_Voltage * HV_Current) / LV_Voltage
• LV_Amps = (kVA * √3 * 1000) / (LV_Voltage * #_Phases)
• HV_Amps = (LV_Voltage * LV_Current) / HV_Voltage)
• HV_Amps = (kVA * √3 * 1000) / (HV_Voltage * #_Phases)
• kVA = (LV_Voltage * LV_Current * #_Phases) / (√3 * 1000)
• kVA = (HV_Voltage * HV_Current * #_Phases) / (√3 * 1000)
• Rounded to 3 decimal places
