What is surge impedance in power systems?
Actually surge impedance is present in a transmission line due to the capacitance of transmission line. Now this capacitor attends the reactive power of the transmission line to energise its magnetic flux. now due to the flux the impedance will increase and the power is reactive too. due to the impedance loss is more.
What is meant by radial feeder?
In a power system, a "radial feed" is one where a source is only present at one end of the transmission line. If a source of power is present at both ends, it is said to be a networked line.
How much power can a transmission line carry?
700 Billion voltsAnswerFirst of all, power is expressed in watts, not in volts! Your answer cannot be answered in any straightforward way, because it depends upon too many variables. For example: At what voltage is the transmission line operating? What is the current-rating of its conductors? How many conductors comprise each line? Etc.
What is the efficiency of a transmission line?
Transmission line efficiency is power at the recieving-end of the line compared to the power at the sending-end of the line and is expressed as a percentage, so this can be formulated. % efficiency = load power (output) / source power (input) x 100 In the line, there are power losses. to calculate this we use the formula: power loss = 3.I2.R where I is current and R is resistance. Now that we have the losses, we know the difference between the input and the output. So, for example, if one had the output value known, then to get the input we just add the loss to the output or if had the input known, just subtract the loss from it to get the output. hope that helps
Why copper is used in electrical transmission line?
Copper is a good conductor and is fairly strong. It generally is not used in power transmission lines due to cost - generally aluminimum is used.
What is mean by compensated and uncompensated power transmission line?
Power transmissions lines are inductive by nature. Power in AC systems is transmitted by varying the phase angle between source and receiving end following the below equation: Vsource * Vrecieve * sin (phi) / (Zsource + Zrecieve + Zline) V = the voltage phi = angle between source and receiving end voltage Z = impedance, Zsource = the impedance behind the source end Series compensating lines is accomplished by adding capacitors in series on a line, which reduces the Zline term in the above equation. This allows more power to be transmitted from one end to the other.
Why does a 2003 impala transmission loses power?
TRANSMISSION LINE LOSSES
What is the formula for calculating power loss in transmission lines?
The formula for calculating power loss in transmission lines is Ploss I2 R, where Ploss is the power loss, I is the current flowing through the transmission line, and R is the resistance of the transmission line.
What is the formula for calculating power loss in a transmission line?
The formula for calculating power loss in a transmission line is Ploss I2 R, where Ploss is the power loss in watts, I is the current flowing through the line in amperes, and R is the resistance of the line in ohms.
How do you transmit ac power flow in HVDC transmission line?
You don't! That's the whole point of a d.c. transmission line.
Performance of transmission line with respect to Nigeria power system?

Which line requires compensation?
Basically an AC transmission line require compensation in terms of reactive power. To push the active power across a transmission line certain amount of reactive power is necessary. In AC transmission line reactive power is generated and consumed. Generator is responsible for the production of reactive and active power both. Than this reactive power is consumed by the load and transmission line. Additional reactive power s supplied by the capacitor. This extra power supplied by the capacitor is termed as reactive power compensation. Requirement of this reactive power is there because reactive power is necessary to maintain the voltage stability.
How many max transmission voltage in India?
There are three types of transmission lines of India given follows ---- 1-long transmission line( which is used grid to power suppliers plant ) 2-medium transmission line ( which is used power supplier plant to the industry ) 3- short transmission line ( which is used transformer to the consumers )

What are the secondary constant of transmission line?
The secondary constants of a transmission line are the surge impedance, propagation constant, attenuation constant, and phase constant. These constants determine the behavior of signals traveling through the transmission line and are important for analyzing the performance of the line in terms of signal integrity and power transmission.
Meaning of volunteer?
