Three Phase Heater Current Calculation

We engineer thermal solutions for the world s toughest industrial heating applications.

Three phase heater current calculation.

Locate heater rated voltage. 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.

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. For both wye and delta balanced loads wye and delta equivalent. Locate actual applied voltage. 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.

In the a phase you have 80 6a b phase 65 8a and c phase 73 2a that s it. 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. V v i a r ω the power p in watts w is equal to the voltage v in volts v.

Chromalox is a thermal technology company. Enter the the current in amperes a. The three phase power calculator calculates the active and reactive power current from the following parameters. Enter 2 values of magnitude phase angle to get the other values and press the.

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. Volts x 1 73 applied vs. 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. User manuals specification sheets cad drawings and more.

Ohm s law calculator 3 phase delta wye calculator. Rated kw factors rated voltage applied voltage. Calculate reset. The formula to find amps for a three phase ac circuit is a little different than the formula for a single phase circuit.

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. The three phase current as you are trying to calculate it does not exist. Enter the phase to phase v ll voltage for a 3 phase ac supply in volts. To calculate kva you need to enter the known values of voltage and the current into the respective fields.
