Malfunctions of telecommunication equipment caused by electromagnetic interference are increasing along with the trend of saving power and operating equipment at low voltage. Malfunctions of power units frequently occur due to lightning currents induced on ac mains lines of access network equipment settled at outdoor locations. In this paper, we have developed the circuit breaker reducing lightning surge currents induced on ac mains line of the telecommunication equipment located in outdoor locations. Recently, PLT (Power Line Telecommunication) using from 2 through 30 MHz signal has been provided broadband communication over power lines. We have developed the blocking filter reducing the emission noise caused by PLC system. This filter has the 40dB reducing factor and a 1/3 at the volume smaller than the conventional one. |
