Description:

Coupling Capacitor

  • Coupling capacitor connects the carrier equipment to the transmission line.
  • The coupling capacitor’s capacitance is of such a value that it offers low impedance to carrier frequency (1/ωC) but high impedance to power frequency (50 Hz).For example 2000pF capacitor offers 1.5MΩ to 50Hz but 150Ω to 500kHz.
  •  allows carrier frequency signal to enter the carrier equipment.
  • To decrease the impedance further and make the circuit purely resistive so that there is no reactive power in the circuit, low impedance is connected in series with coupling capacitor to form resonance at carrier frequency.
