Convert Voltage (V) to Kilo-Watts (KW) Calculation
To convert volts to KW , Please provide the values below:
To calculate volts to Kilo-Watts DC circuit, use the following formula:
In DC circuits,Power (P) in kilo-watts (KW) is equal to the DC (Dircet current) voltage (V) times the current (I) in amps divided by 1000.
To calculate volts to KW single phase, use the following formula:
In AC circuits single phase,Real Power (P) in kilo-watts (KW) is equal to the RMS voltage (V) times the current (I) in amps times the power factor (pf) divided by 1000
To calculate voltage to KW Three phase, use the following formula:
In AC circuits three phase,Real Power (P) in kilo-watts (KW) is equal to √3 times the RMS voltage (V) times the current (I) in amps times the power factor (pf) divided by 1000
For Example 01
If an DC motor takes 12amp and voltage 230V . Calculate the kilo-watts of the motor.
Answer
Where,
I= 12amps ,V = 230v
We Know
P (KW) = V(V) x I(A) ÷ 1000
P(KW) = 230 x 12 ÷ 1000
P (KW) = 2.760
P = 2.760 KW
For Example 02
If an single phase Induction motor takes 15A and voltage 380V at 0.99 (lag) power factor from the AC source and runing time 6 hours. Calculate the real power (KW) of the motor.
Answer
Where,
I= 15amps ,V = 380v ,pf=.99
We Know
P (KW) = V(V) x I(A) x pf ÷ 1000
P(KW) = 380 x 15 x 0.99 ÷ 1000
P (KW) = 5.643
P = 5.643 KW
For Example 03
If an three phase Induction motor takes 25A and lone to line voltage 400V at 0.94 (lag) power factor from the AC source and runing time 6 hours. Calculate the real power (KW) of the motor.
Answer
Where,
I= 25amps ,V = 400v ,pf=0.94
We Know
P (KW) = √3 x V(V) x I(A) x pf ÷ 1000
P(KW) = √3 x 400 x 25 x 0.94 ÷ 1000
P (KW) = 16.281
P = 16.281 KW
