Answer / vinaya

Calculation of voltage regulation is an important part of power system analysis.
ACSR, AAAC conductors of different sizes are available. Usage of a particular conductor depends on factors like voltage rating of the transmission line, power factor, total load, length of the line etc. For example following are the KW-KM values for 1% voltage drop at 60 deg C at P.F
1.00 - 41613; 0.9 - 25438; 0.8- 20966; 0.7- 17787 FOR acsr Coyote 26/2.54 + 7/1.91 conductor.
Generally the formula used for calculation of Regulation is
% regulation @ --- p.f = KW-KM X RC of conductor/P.F x D.F

Answer / shiva

The above ans is general for calculating the regulation in
T.L. Due to capacitance effect in overhead transmission line
(short, medium, long) the regulation forumula is vaired.

Answer / sks

Voltage Regulation is denoted in percentage.

Voltage regulation[%]= Vs-Vr*100
-----------
Vs
Vs = Voltage at Sending end.
Vr = Voltage at Recieving end.

different type of Conductor are useful as per current
carring capacity,resistance,length of
line,weatherproff,economics, market avilability, apearance
etc.
