Question
```How voltage regulation is calculated for over head
transmission line? What do we mean by Conductor constant
while calculating voltage regulation? how it is differ for
for diffrent type of conductor say AAAC DOG & AAAC RACOON
conductor?```

# 1
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.

# 2
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

# 3
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.

  Question Asked @ Answers Other Electrical Engineering Interview Questions what is the difference between equipment earth and system earth. 1 Why all voltage level are multiples of 11, like 220V, 440V, 1100V instead of 200V, 400V, 1000V? Indian-School-of-Mines 9 when transformer in load condition neutral earth testing wheater we can do it or not 1 what is electricity APGenco 3 we can stepdown the voltage from 230/12v ,and we use the voltage for various electronics components why can't we step up the voltage from 12/230v if we can shall we use the voltage for domestic single phase supply Areva 5 Re: how to calculate diesel consumption of a D.G.Set? Answer # 1 We can not calculate the diesel comsumption...depending upon load it will conume the diesel...suppose the 1500kva D.G is running and the load is 1000kw means it will consume 150-200 liters per hour.... 5 We know that, in case if there is a faulty insulation,or sc, the current is bypassed to earth through the earth wire that has low resistance.Actually, what will happen to that current that flows through gnd?In that case,if we come in contact with that faulty appliance, wont that current flow through us as we form a closed path by standing in gnd?Is grounding a safety measure? 3 The importance of resonant filters in converters? 1 Why Motors are generally supplied with 3 core cables??? why not 4C?? 5 What are the neccessary safety arrangements before commissioning of HV substation? 1 What is ill conditioned power system? 1 can u guys pls suggest a good material for learning abt switch yard and its components 2 For more Electrical Engineering Interview Questions Click Here
