This calculator brings conversions of units of electrical power. Electrical power is of different types but this converter converts units for apparent electrical power. Apparent electrical power is measured in volt-amperes.
Apparent power is actually a product of current (I) in amperes and voltage(V) in volts hence its unit is volt-ampere. This calculator changes the given volts and amperes in kilovolt-amperes (kVA). So you just have to provide the electric current value in amperes and voltage in volts in the respective given boxes to get them converted into kVA.
Put values of amperes (amp) and volts (V) and press calculate:
The apparent power S in kilovolt-amps is equal to current I in amps, times the voltage V in volts, divided by 1000:
S(kVA) = I(A) × V(V) / 1000
The apparent power S in kilovolt-amps is equal to phase current I in amps, times the line to line RMS voltage VL-L in volts, divided by 1000:
S(kVA) = √3 × I(A) × VL-L(V) / 1000
The apparent power S in kilovolt-amps is equal to phase current I in amps, times the line to neutral RMS voltage VL-N in volts, divided by 1000:
S(kVA) = 3 × I(A) × VL-N(V) / 1000
This calculator works on an equation:
S (Apparent power) = V (voltage) × I (current) / 1000
This calculator gives answers of apparent power in kVA ( kilovolt amperes ). Multiplication of current (amp) and voltage (volt) makes volt-ampere a unit of power and the equation divides these volt-amperes by 1000 to convert them into kilovolt amperes (kVA). This calculator calculates apparent power units both for single-phase as well as 3 phase voltage. In 3-phase voltage, there are further two types i.e line to line and line to neutral voltages.
For calculation of units of power in all three types of voltage, the units in the equation " S (Apparent power) = V(voltage) × I(current) / 1000 "remain the same. i.e ampere for current, volt for voltage and kVA for power.
But in three-phase line to line calculations, this equation is multiplied by √3 and for the line to neutral voltage calculation, it is multiplied by 3. In both cases equation is multiplied by numbers which do not change the unit of power and the unit remains the same i.e kVA.
Amps represent the electrical current flowing through the electrical circuit. Kilovolt-amps or kVA are an indicator of apparent power in circuits which is why 1 kVA equals to 1,000 amperes or volts. Since amps and KVA are distinct in an electrical circuit the voltage is also required to convert them.
