Physics · Transmission Lines
In a short transmission line with negligible shunt capacitance, if the load power factor is improved from 0.8 lagging to 0.8 leading while keeping the load current magnitude constant, what is the primary effect on the receiving-end voltage?
- 1The receiving-end voltage decreases due to additive drops in voltage.
- 2The receiving-end voltage decreases due to increased capacitive drop.
- 3The receiving-end voltage increases because the voltage drop becomes subtractive.✓
- 4The receiving-end voltage increases due to higher reactive power demand.
Correct answer
The receiving-end voltage increases because the voltage drop becomes subtractive.
