Circuits for carrier trapping of resonant taps

IN THE APPLICATION of carrier current to rural distribution lines, the problem of treatment of resonant taps is more acute than in similar installations on high-voltage transmission circuits. Large numbers of taps between 1/4 mile and 1 mile in length will be found on these lines. Taps of those lengths will be resonant at frequencies between 50 and 150 kc and in effect will short-circuit the carrier.
