Three Phase Heater Current Calculation

Volts x 1 73 applied vs.

Three phase heater current calculation.

We engineer thermal solutions for the world s toughest industrial heating applications. I a 1000 p kw 3 pf v l n v typical power factor values. 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. Enter the phase to phase v ll voltage for a 3 phase ac supply in volts.

Ac ohm s law calculator. The formula to find amps for a three phase ac circuit is a little different than the formula for a single phase circuit. Typical 3 phase wiring diagrams and equations for resistive heaters definitions. To calculate kva you need to enter the known values of voltage and the current into the respective fields.

Calculate reset. 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. In the a phase you have 80 6a b phase 65 8a and c phase 73 2a that s it. 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.

For both wye and delta balanced loads wye and delta equivalent. Leverage watlow s growing toolkit of calculators equations reference data and more to help design your thermal system. 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.

Ohm s law calculator 3 phase delta wye calculator. Locate heater rated voltage. V v i a r ω the power p in watts w is equal to the voltage v in volts v. Locate actual applied voltage.

Do not use typical power factor values for accurate calculations. Enter 2 values of magnitude phase angle to get the other values and press the. Rated kw factors rated voltage applied voltage. Line current 1 phase amps kw x 1000.

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. The three phase current as you are trying to calculate it does not exist. 120 208 220 230 240 277 440 460 480. Volts line current 3 phase amps kw x 1000.
