Voltage Drop Calculator
Voltage Drop CalculatorThe Voltage Drop Calculator is used to compute the voltage drop in volts (V), percentage of voltage drop (%) and the wire resistance. (Ω). The first procedure is to select the type of wire. It can either be Copper, Gold, Carbon Steel or the others. You can also adjust the size of wire diameter and wire length to match the specifications. Afterwards, you can select the type of current in DC (Direct Current) or AC (Alternating current) Single Phase and Three Phase. Click on the calculate button to execute the calculations. Your results will be displayed below the two control buttons of the converter.
For example;If you have Aluminium as your wire type and the diameter size is in millimeters find the voltage drop in volts, percentage of voltage drop and wire resistance.
SolutionYou will first select the choices according to your requirements and then click the ‘Calculate’ Button. The results will be displayed as;
Voltage drop in volts = 0.000675553
Percentage of voltage drop = 0.000562961
Wire resistance =0.000675553
Formula of calculating the DC/Single Phase currentV drop (V) = I wire (A) x R wire (Ω)
= I wire (A) x (2 x L (ft) x R wire (Ω/kft) / 1000 (ft/kft)), which means that the voltage drop in volts is computed multiplying the wire current in amps by; 2 times the length in feet by the wire resistance per 1000 feet in ohms. The result is then divided by 1000.
V drop (V) = I wire (A) x R wire (Ω)
= I wire (A) x (2 x L (m) x R wire (Ω/km) / 1000 (m/km)), where the voltage drop in volts is computed by multiplying the wire current in amps by; two times the length in meters by the wire resistance per 1000 meters in ohms. The answer is then divided by 1000.
Formula of calculating 3 Phase CalculationV drop (V) = √3 x I wire (A) x R wire (Ω)
=1.732 x I wire (A) x (L (ft) x R wire (Ω/kft)/1000 (ft/kft))
V drop (V) = √3 x I wire (A) x R wire (Ω)
=1.732 x I wire (A) x (L (m) x R wire (Ω/km)/1000 (m/km))
The Voltage Drop Calculator can be used to perform different conversions within a short period.
