Calculate Feeder Voltage Drop







Formula

The formula to calculate the Feeder Voltage Drop (Vd) is:

\[ V_d = 2 \cdot L \cdot I \cdot (R + X) \]

Where:

Feeder Voltage Drop Definition

A feeder voltage drop refers to the reduction in voltage that occurs as electric current flows through a feeder, which is a type of electrical conductor used to transmit power from a source to a load. This drop in voltage is caused by the resistance and reactance of the feeder material, which impedes the flow of current. The voltage drop can affect the performance of electrical equipment and systems, making it important to calculate and minimize it in electrical design and installation.

Example Calculation

Let's assume the following values:

Using the formula:

\[ V_d = 2 \cdot 100 \cdot 50 \cdot (0.05 + 0.02) = 2 \cdot 100 \cdot 50 \cdot 0.07 = 700 \text{ V} \]

The Feeder Voltage Drop (Vd) is 700 V.
