Three Phase Heater Current Calculation

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

Three phase heater current calculation. Enter the phase to phase v ll voltage for a 3 phase ac supply in volts. The voltage v in volts v is equal to the current i in amps a times the resistance r in ohms ω. Leverage watlow s growing toolkit of calculators equations reference data and more to help design your thermal system. Volts x 1 73 applied vs.

Typical 3 phase wiring diagrams and equations for resistive heaters definitions. 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. Volts line current 3 phase amps kw x 1000.

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. For both wye and delta balanced loads wye and delta equivalent.

Locate heater rated 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. Enter the the current in amperes a. Rated kw factors rated voltage applied voltage.

Locate actual applied voltage. 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. Ac ohm s law calculator. I a 1000 p kw 3 pf v l n v typical power factor values.

The three phase current as you are trying to calculate it does not exist. User manuals specification sheets cad drawings and more. In the a phase you have 80 6a b phase 65 8a and c phase 73 2a that s it. Calculate reset.

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. The three phase power calculator calculates the active and reactive power current from the following parameters. Do not use typical power factor values for accurate calculations. To calculate kva you need to enter the known values of voltage and the current into the respective fields.

Line current 1 phase amps kw x 1000.
