Three Phase Electric Power Calculator

Simple electrical calculator to calculate the three 3 phase electric power in a circuit based on voltage and current.

Three phase electric power calculator.

The phase current i in amps a is equal to the power p in watts w divided by square root of 3 times the power factor pf times the line to line rms voltage v l l in volts v. W applied 3 1 2 u ll i cos φ 3 1 2 u ll i pf 1 where. As an example consider a balanced three phase load consuming 36 kw at a power factor of 0 86 and line to line voltage of 400 v v ll. The power factor of resistive impedance load is equal to 1.

P kw 3 pf i a v l l v 1000. Three phase current simple calculation why is electricity so hard to understand. To calculate kva you need to enter the known values of voltage and the current into the respective fields. Line to line voltage.

It s been a busy few months on different projects or busy couple of decades depending on how i look at it. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power. It is also used to power large motors and other heavy loads. I a p w 3.

Ac three phase watts to amps calculation calculation with line to line voltage. Code to add this calci to your website just copy and paste the below code to your webpage where you want to display this calculator. The power p in kilowatts kw is equal to square root of 3 times the power factor pf times the phase current i in amps a times the line to line rms voltage v l l in volts v divided by 1000. Ac three phase amps to kilowatts calculation calculation with line to line voltage.

For a tutorial on three phase calculations please see. Enter the power factor of the load. Single three phase line kva calculator is an online tool used in electrical engineering to measure the unknown quantity by two known quantities applied to the below formulas for single phase and three phase connection. Enter the phase to phase v ll voltage for a 3 phase ac supply in volts.

The line to neutral phase voltage v ln 400 3 230 v three phase power is 36 kw single phase power 36 3 12 kw now simply follow the above single phase method. With single phase ac power there is only one single sinusoidal voltage. Most ac power today is produced and distributed as three phase power where three sinusoidal voltages are generated out of phase with each other. The three phase power calculator calculates the active and reactive power current from the following parameters.

That said there isn t much extra you have to do when working with three phase power equations so you ll be able to solve whatever three phase. Three phase power is a widely used method for generating and transmitting electricity but the calculations you ll need to perform are a little more complicated than for single phase systems.
