How does a bundled conductor reduce inductance?
By using bundle conductors instead of the single conductor in the transmission line increases the GMR of the conductors. Hence, by using bundle conductors GMR is increased, so inductance L decreases, and capacitance C increases.
How can you reduce the inductance of a transmission line?
Bundled conductor reduces the radio interference and the magnetic flux linkage between two adjacent conductor by increasing the effective resistance of the conductor . Cross bonding reduces the diameter of the conductor and helps to equalizes the voltage drop across the lumped parameter ..
How can bundled conductors reduce the voltage drop across transmission lines?
Bundled conductors per phase reduces the voltage gradient in the vicinity of the line. Thus reduces the possibility of the corona discharge. (Corona effect will be observed when the air medium present between the phases charged up and start to ionize and acts as a conducting medium.
Why bundled conductors are employed in transmission lines?
A bundled conductor reduces the reactance of the electric transmission line. It also reduces voltage gradient, corona loss, radio interference, surge impedance of the transmission lines. As the self GMR of the conductor increases, the inductance of the conductor decreases.
What is the inductance in transmission line?
Inductance of Two Wire Single Phase Transmission Line Let us consider the magnitude of current in both conductors are same and hence IA = – IB, Now, total flux linkage in conductor A = flux linkage by self-current of conductor A + flux linkage on conductor A due to current in the conductor B.
What are bundled conductors discuss the advantages of bundled conductors when used for overhead lines explain transposition of power lines?
A bundled conductor reduces the reactance of the electric transmission line. It also reduces voltage gradient, corona loss, radio interference, surge impedance of the transmission lines. By making bundle conductor, the geometric mean radius (GMR) of the conductor increased.
Why bundled conductors are used in transmission lines?
How do bundled conductors reduce corona?
Conductor bundling increases the effective radius of the lines conductor and also reduces the electric field strength near the conductors [13]. Therefore increasing the number of conductors in a bundle reduces the effects of corona discharge.
What are the factors depend on the inductance of transmission line?
Following factors affect the inductance in a circuit:
- Number of Wire Turns in the Coil. The greater the number of turns of wire in the coil, the greater the inductance.
- Coil Area. The greater the coil area, the greater the inductance.
- Core Material.
- Coil Length.
