Three Phase Heater Current Calculation

V p phase voltage v l line voltage i p phase current i l line current r r1 r2 r3 resistance of each branch w wattage w delta 3 w wye w odelta w delta w owye w wye.

Three phase heater current calculation.

The formula to find amps for a three phase ac circuit is a little different than the formula for a single phase circuit. The voltage v in volts v is equal to the current i in amps a times the resistance r in ohms ω. Enter the phase to phase v ll voltage for a 3 phase ac supply in volts. The three phase power calculator calculates the active and reactive power current from the following parameters.

To calculate kva you need to enter the known values of voltage and the current into the respective fields. In the a phase you have 80 6a b phase 65 8a and c phase 73 2a that s it. Locate actual applied voltage. Calculate reset.

120 208 220 230 240 277 440 460 480. 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. Locate heater rated voltage. I a 1000 p kw 3 pf v l n v typical power factor values.

Amps kw 1 000 3 pf volts for example find the current of a 25kw three phase generator with an efficiency of 80 at 240 volts. Ohm s law calculator 3 phase delta wye calculator. Ac ohm s law calculator. Chromalox is a thermal technology company.

Enter the the current in amperes a. User manuals specification sheets cad drawings and more. Volts x 1 73 applied vs. 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.

Rated kw factors rated voltage applied voltage. Line current 1 phase amps kw x 1000. The three phase current as you are trying to calculate it does not exist. Volts line current 3 phase amps kw x 1000.

Typical 3 phase wiring diagrams and equations for resistive heaters definitions. Do not use typical power factor values for accurate calculations. Leverage watlow s growing toolkit of calculators equations reference data and more to help design your thermal system. For both wye and delta balanced loads wye and delta equivalent.

You still have your three phase system with the current in each line being slightly different if all the line currents were the same it would just be a balanced three system.
