What is coupling capacitor with capacitive reactance?

Coupling capacitor with capacitive reactance offers low impedance to the high-frequency signals, and high impedance to the low-frequency signals. Hence high-frequency carrier signals get blocked by Line Trap, and travel through a coupling capacitor. And low-frequency power signals pass through Line Trap and get blocked by the coupling capacitor.

What is coupling capacitor?

And coupling capacitor is the connecting link between the power transmission line and the terminal assembly of the carrier signal panel, which is connected to the power transmission line before the Line Trap. Line Trap is nothing but an inductive coil with inductive reactance. And inductive reactance XL=2 π fL.

What is a line trap & coupling capacitor?

Let’s see. Line Traps are connected in series with the power transmission line. And coupling capacitor is the connecting link between the power transmission line and the terminal assembly of the carrier signal panel, which is connected to the power transmission line before the Line Trap.

What is a phase-to-phase coupling?

most popular is center phase to ground. Next there are the phase-to-phase coupling types. In this type the carrier signal is coupled between two phases of the power line, and the energy in the two phases are out of phase with each other, in most cases. The last form of coupling is called mode 1 and is a special case of coupling to all three phases.

Why is a line trap inserted between busbar and coupling capacitor?

The coil of the line trap provides a low impedance path for the flow of the power frequency energy. Since the power flow is rather large at times, the coil used in a line trap must be large in terms of physical size. Hence a line trap unit/Wave trap is inserted between busbar and connection of coupling capacitor to the line.

What is the difference between line tuner and coupling capacitor?

The line tuner/coupling capacitor combination provides a low impedance path to the power line by forming a series resonant circuit tuned to the carrier frequency. On the other hand, the capacitance of the coupling capacitor is high impedance to the power frequency energy.
