ActiveCoupling capacitors and capacitor dividers—Part 2: DC or AC single-phase coupling capacitor connected between line and ground for power line carrier-frequency (PLC) application
耦合电容器及电容分压器 第2部分：接于线与地之间用于电力线路载波（PLC）的直流或交流单相耦合电容器
Application Summary AI generated
This standard specifies the performance requirements, testing methods, and ratings for DC or AC single-phase coupling capacitors connected between a power line and ground, specifically designed for power line carrier-frequency (PLC) communication systems. It is applied in high-voltage power transmission networks to ensure reliable signal coupling for data transmission over power lines, while maintaining electrical safety and insulation coordination. The standard is used by manufacturers and utilities for design, qualification, and procurement of capacitors in PLC-based teleprotection, remote control, and monitoring applications.
