| Application: LT-130 line traps are connected  in series with the high-voltage lines and used for  transmission of 20~500KHz speech, energy management data and power system  protection signals.  The purpose of PLC  line traps: 
                  Make the defined impendence  on power line terminal and reduce loss of carrier signal. Isolate the RF  signal from other sections of power line. The PLCs on different sections could  use same frequency band |
