Increasing the separation between the three phases of a transmission line has an impact on the inductance and capacitance of the line. The correct answer, option 'C', states that the inductance will increase and the capacitance will decrease. Let's understand why this is the case.
Inductance:
When the separation between the phases is increased, the distance between the conductors also increases. This results in an increase in the mutual inductance between the conductors. Mutual inductance is the phenomenon where the magnetic field generated by one conductor induces a voltage in the adjacent conductors. As the distance between the conductors increases, the magnetic field will have a larger area to couple with, leading to an increase in the mutual inductance.
Capacitance:
On the other hand, when the separation between the phases is increased, the distance between the conductors also increases. This results in a decrease in the capacitance between the conductors. Capacitance is the ability of a system of conductors to store electrical energy in an electric field. When the distance between the conductors increases, the electric field between them weakens, reducing the capacitance.
Overall effect:
So, when the separation between the three phases of a transmission line is increased, the inductance will increase due to the larger area for magnetic field coupling. At the same time, the capacitance will decrease due to the weakening electric field between the conductors. Therefore, the correct answer is option 'C' - the inductance will increase and the capacitance will decrease.
It's important to note that the inductance and capacitance of a transmission line have a significant impact on its performance. The inductance affects the line impedance, while the capacitance affects the line charging current and voltage levels. Understanding these characteristics is crucial for the design and operation of efficient and reliable transmission systems.
