Three Phase Heater Current Calculation

Volts line current 3 phase amps kw x 1000.

Three phase heater current calculation.

The three phase current as you are trying to calculate it does not exist. 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. 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. Ohm s law calculator 3 phase delta wye calculator.

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. Locate heater rated voltage. Typical 3 phase wiring diagrams and equations for resistive heaters definitions. Rated kw factors rated voltage applied voltage.

For both wye and delta balanced loads wye and delta equivalent. Do not use typical power factor values for accurate calculations. 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. The three phase power calculator calculates the active and reactive power current from the following parameters.

Enter the the current in amperes a. The formula to find amps for a three phase ac circuit is a little different than the formula for a single phase circuit. User manuals specification sheets cad drawings and more. Volts x 1 73 applied vs.

We engineer thermal solutions for the world s toughest industrial heating applications. V v i a r ω the power p in watts w is equal to the voltage v in volts v. In the a phase you have 80 6a b phase 65 8a and c phase 73 2a that s it. 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.

Chromalox is a thermal technology company. Locate actual applied voltage. 120 208 220 230 240 277 440 460 480. To calculate kva you need to enter the known values of voltage and the current into the respective fields.

Calculate reset. I a 1000 p kw 3 pf v l n v typical power factor values. Line current 1 phase amps kw x 1000. The voltage v in volts v is equal to the current i in amps a times the resistance r in ohms ω.
