Power line carrier (PLC) technology is a traditional, economical and reliable method of power systems communication. When connected in series with the transmission line, PLC reactors (line traps) present low impedance at power frequency and maintain high impedance at power line carrier frequencies (30kHz – 500kHz). The international sales of line traps produced by Coil lnnovation are handled by the company ARTECHE located in Spain, which has an exclusive agreement with Coil lnnovation for most of the international market.
