The conversion of 1.5 kVA to amps results in approximately 6.82 amps. This calculation helps understand how much current flows in a circuit rated at 1.5 kVA, assuming a standard power factor.
To convert from kilovolt-amperes (kVA) to amps (A), you divide the apparent power in volt-amperes (VA) by the voltage in volts (V), considering the power factor. Since 1.5 kVA equals 1500 VA, and assuming a standard voltage, the formula used is amps = VA / V. For example, at 220V, 1500 VA divided by 220V gives about 6.82 amps.

Conversion Formula
The formula to convert kva to amps is: amps = (kva * 1000) / voltage. This works because kva is a measure of apparent power, and dividing by the voltage gives the current in amps. The power factor is assumed to be 1, meaning all power is reactive and real power.
For example, with 1.5 kva, you multiply by 1000 to get 1500 VA. If the system voltage is 230V, then amps = 1500 / 230 = approximately 6.52 amps. This calculation assumes a power factor of 1, which is common in many simplified calculations.
Conversion Example
- Convert 2 kva to amps:
- 1500 VA (since 2 kva * 1000)
- Divide by 230V: 1500 / 230 = approximately 6.52 amps
- Convert 0.75 kva to amps:
- 750 VA
- 750 / 230 = approximately 3.26 amps
- Convert 5 kva to amps:
- 5000 VA
- 5000 / 230 = approximately 21.74 amps
- Convert 3.2 kva to amps:
- 3200 VA
- 3200 / 230 = approximately 13.91 amps

Conversion Definitions
kva
kva (kilovolt-amperes) measures the apparent power in an electrical circuit, combining both real power and reactive power, used to rate transformers and generators. It indicates the total capacity without considering power factor, a key factor in electrical systems.
amps
Amps (amperes) measure the flow of electric current in a circuit, representing the number of electrons passing a point per second. It indicates the actual current load, crucial for designing and selecting electrical components and ensuring safety in circuits.
Conversion FAQs
How does the power factor influence the amps calculated from 1.5 kva?
The power factor affects the real current flow in a circuit. When the power factor is less than 1, the actual amps may be higher than calculated assuming a power factor of 1. To get precise amps, multiply kva by 1000, then divide by voltage and by the power factor.
Can I convert 1.5 kva to amps at any voltage?
Yes, but the result depends on the voltage used in the calculation. The formula is VA / voltage. So, changing voltage values will change the amps. For accurate calculations, always specify the voltage, and consider the power factor if needed.
Why is the conversion from kva to amps important for electrical installations?
This conversion helps ensure equipment is correctly rated, prevents overloads, and optimizes system efficiency. Knowing the amps helps in selecting the right circuit breakers, wiring, and safety devices, especially when dealing with large loads or complex systems.
