Working Principle

The voltage rise in a transmission line is caused by the impedance of the line (resistance and reactance) when current flows through it. The voltage rise (ΔV) can be calculated using the formula:

ΔV = I × (R + jX)

Where:

  • I = Load Current (amps)
  • R = Line Resistance (ohms)
  • X = Line Reactance (ohms)
  • j = imaginary unit (√-1)

The total voltage rise is the vector sum of the real and imaginary components, and the percentage rise is the ratio of the total voltage rise to the source voltage.

Applications
