Three phase electric power calculator.

Enter the the current in amperes a. To calculate kva you need to enter the known values of voltage and the current into the respective fields. 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. With single phase ac power there is only one single sinusoidal voltage.

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. The three phase power calculator calculates the active and reactive power current from the following parameters. Ac three phase watts to amps calculation calculation with line to line voltage. 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.

For a tutorial on three phase calculations please see. A three wire three phase circuit is usually more economical than an equivalent two wire. 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.

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. 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. It is also used to power large motors and other heavy loads. W applied 3 1 2 u ll i cos φ 3 1 2 u ll i pf 1 where.

P kw 3 pf i a v l l v 1000. Three phase electric power is a common method of alternating current electric power generation transmission and distribution. Most ac power today is produced and distributed as three phase power where three sinusoidal voltages are generated out of phase with each other. It is a type of polyphase system and is the most common method used by electrical grids worldwide to transfer power.

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

Enter the power factor of the load. The power factor of resistive impedance load is equal to 1.
