For a transmission line with negligible losses the lagging reactive power (VAR) delivered at the receiving end
For a transmission line with negligible losses, the lagging reactive power (VAR) delivered at the receiving end, for a given receiving end voltage, is directly proportional to the
Right Answer is:
Line voltage drop
SOLUTION
- The VARs (lagging reactive power) delivered by a line is proportional to the line voltage drop and is independent of torque angle δ.
- Hence, in a transmission system if, the lagging reactive power demand of the load is large, the voltage profile at that point tends to sag rather sharply.
- To maintain the desired voltage profile, the VARs demand of the load must be met by employing condensers.
