Conversion using the KVA to Amps Formula

How to Calculate Amperage from Apparent Power kVA and Voltage volts using AC Single Phase current.

The Current I in amps is calculated as the 1000 times the apparent power S in kilovolt-amps, divided by the voltage in volts v. Plug these values into the formula:

Amps = 1000 × KVAVolts

For Example, let's find the current for a 220-volt circuit with 40 kVA of apparent power.

Current(I) = 1000 × Apparent Power(S)Voltage(V)

or, I(A) = 1000 × 40 KVA220 Volts

or, Amps = 181.81A

How to Calculate Amperage from Apparent Power kVA and Voltage volts using AC 3-phase current for Line-to-Line Voltage.

The phase current I in amps (with balanced loads) is calculated as to 1000 times the apparent power S in kilovolt-amps, divided by the square root of 3 times the line-to-line RMS voltage V_L-L in volts v. Plug these values into the formula:

Amps = 1000 × KVA3 × Volts

For Example, let’s find the current for a 440-volt 3-phase circuit with 60 kVA of apparent power.

Current(I) = 1000 × Apparent Power(S)3 × Voltage(line-line)

or, I(A) = 1000 × 60 KVA3 × 440 Volts

or, Amps = 78.72A

How to Calculate Amperage from Apparent Power kVA and Voltage volts using using AC 3-phase current for Line-to-Neutral Voltage.

The phase current I in amps (with balanced loads) is calculated as to 1000 times the apparent power S in kilovolt-amps, divided by the 3 times the line-to-line RMS voltage V_L-L in volts v. Plug these values into the formula:

Amps = 1000 × KVA3 × Volts

For Example, let's find the current for a 440-volt 3-phase circuit with 30 kVA of apparent power.

Current(I) = 1000 × Apparent Power(S)3 × Voltage(line-line)

or, I(A) = 1000 × 30 KVA3 × 440 Volts

or, Amps = 22.72A

Frequently Asked Questions - FAQs for KVA to Amps Calculator

What is apparent power (VA) voltage?

A volt-ampere (VA) is the voltage times the current flow feeding an electrical load. A kilovolt-ampere (kVA) is 1000 volt-amperes. Electrical Real power is measured in watts (W)

What is my kVA capacity?

Your Authorised Service Capacity (measured in kVA) is the level of 'apparent power' reserved from the network to guarantee the provision of a certain volume of power.

What is 1 watt (w)?

A body is said to have 1 watt of power if it can perform 1 joule of work in 1 second. Power is defined as the rate at which work is performed, or energy is converted.

What is kVA to kW?

The formula for converting kVA into kW is:
For example, a 200kVA generator with a power factor of 0.8 outputs 80kW actual power; 200 kVA × 0.8 = 160 kW.

What is 5 kVA in amps?

5 kVA is equivalent to 5000-volt amps.
