With this tab the user can calculate an estimated voltage drop by using resistance and reactance date that comes straight from the National Electric Code or NEC. A 10 volt drop at 0 PF on a 120 Volt circuit will result in a voltage of. As can be seen from equations Real power P is obtained by multiplying apparent power S by the power factor cosδ-β.
Resistance of conductor per unit. A 10 volt drop at 100 PF on a 120 Volt circuit will result in a voltage of 110 Volts. Go back to top.
1 Phase AC 3 Phase AC or DC. Phase at 80 power factor. Total length of conductor.
Therefore the voltage drop on this cable is. Call 310-835-8080 to know more about the power factor calculator. Multiply current in amperes by the length of the circuit.
Use our power factor calculator to calculate the apparent power reactive power and capacitance of a capacitor. Vdrop V Iwire A RwireΩ Iwire A 2 Lft RwireΩkft 1000 ftkft The voltage drop V in volts V is equal to the wire current I in amps A times 2 times one-way wire length L. 5364V For a 240V.
To calculate voltage drop. 7200 x 745 5364000 Multiply by 1 5364000 x 1 5364000 phase 1 Place decimal point 6 places to left. This states that the voltage potential across the conductor is equal.
Specify the voltage in volt V. And select the phase arrangement. On a simple example.
Since there are 4 runs of cable total resistance and reactance will be divided by 4 accordingly. This gives volt loss to be expected. It should be noted that a pure resistor will only absorb real power.
