### Formula
|

|
||||
The formula for active power in a three phase system is given by
|
||||
|
||||
$$
|
||||
P = \sqrt{3} \times V_{L} \times I_{L} \times PF
|
||||
$$
|
||||
|
||||
where:
|
||||
|
||||
* $P$ is the power in watts,
|
||||
* $P$ is the active power,
|
||||
* $V_{L}$ is the line voltage,
|
||||
* $I_{L}$ is the line current,
|
||||
* $PF$ is the power factor.
|
||||
|
||||
The formula for apparent power in a three phase system is given by
|

|
