Three Phase Heater Power Calculation

I am programming an app for ordering 3 phase heaters and i have an argument to resolve with a coworker.

Three phase heater power calculation.

The three phase power calculator calculates the active and reactive power current from the following parameters. Calculation with line to neutral voltage. We engineer thermal solutions for the world s toughest industrial heating applications. Lv and mv cables up to 33 kv with current capacity in accordance with bs 7671 era 69 30 and iec 60502.

Enter the phase to phase v ll voltage for a 3 phase ac supply in volts. All your cables for all your projects. Leverage watlow s growing toolkit of calculators equations reference data and more to help design your thermal system. 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.

Enter the the current in amperes a. P kw 3 pf i a v l n v 1000. Enter the power factor of the load. Lets say i have a 208v 3 phase heater delta connection with a heating element on each leg l1 l2 l3.

To calculate kva you need to enter the known values of voltage and the current into the respective fields. User manuals specification sheets cad drawings and more. Do not use typical power factor values for accurate calculations. The power p in kilowatts kw is equal to 3 times the power factor pf times the phase current i in amps a times the line to neutral rms voltage v l n in volts v divided by 1000.

My calculation for amps in each leg is 15kw 1000 208v 1 73 41 7 amps. Chromalox is a thermal technology company. Ohm s law calculator 3 phase delta wye calculator. Cable sizing software select size and manage your power cables using mycableengineering.

I a 1000 p kw 3 pf v l n v typical power factor values. Typical power factor values. 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 phase current i in amps a is equal to 1000 times the power p in kilowatts kw divided by 3 times the power factor pf times the line to neutral rms voltage v l n in volts v.

Do not use typical power factor values for.
