How to convert kilowatts(KW) to amps(A)?
kilowatts to amps calculation formula in DC
I=The current I in amps
P=the power P in kilowatts
V=the voltage V in volts
So that you can say that amps(A) are equal to 1000 times kilowatts(KW) divided by volts
or
Let’s take one Example
Example#1
Find out the current in amps(A) Where the power utilization is 20 kilowatts and the voltage supply in circuit is 23 volts.
P=20kw
V=23
I=1000*20/23
I=869.56amps
kilowatts to amps calculation formula in AC single phase
I=The phase current I in amps
P=the real power P in kilowatts
PF=the power factor PF times
V=the RMS(root mean square) voltage V in volts:
So that definition is amps(A) are equal to 1000 times kilowatts(kw) divided by pf times volts.
or
Let’s take one Example
Example#2
Find out the current in amps(A) where the power utilization is 25 kilowatts, the pf is 0.8 and the RMS(root mean square) voltage supply is 230 volts.
P=25KW , V=230V , PF=.8
I = 1000 × 25kW / (0.8 × 230V) = 3.75A
I=1000*25/.8*230
I=25000/184
I=135.86amps
kilowatts to amps calculation formula AC three phase
I=The phase current I in amps
P=the real power P in kilowatts
PF=the power factor PF times
VL-L=the line to line RMS voltage VL-L in volts:
So using above formula amps(A) are equal to 1000 times kilowatts(kw) divided by √3 times pf times volts.
Let’s take one Example
Example#3
Find out the current in amps(A) where the power utilization is 0.55 kilowatts, the PF is 0.8 and the voltage supply in circuit is 120volts
I(amps) = 1000 × 0.55kW / (√3 × 0.8 × 120V) =3.307A
How to convert kw to amps in three phase system with line to neutral voltage
I=average current in 3 phase system
pf=power factor
Let’s take one example:
Example#4
Find out the current in amps(A) where the power utilization is 0.55 kilowatts, the PF is 0.8 and the
voltage supply in circuit is 120volts.
I(amps) = 1000 × 0.55kW / (3 × 0.8 × 120V) =1.9A
