Application Summary AI generated
GB/T 7330-2008 specifies technical requirements, test methods, and acceptance criteria for line traps used in high-voltage alternating current (AC) power systems, primarily at frequencies from 40 kHz to 500 kHz. These devices are installed on transmission lines to block high-frequency communication signals from entering substations while allowing normal power frequency current to pass, ensuring reliable operation of power line carrier (PLC) communication systems. The standard applies to utilities, grid operators, and manufacturers involved in the design, testing, and procurement of line traps for power system telecommunication and protection applications.
