What is PLCC?
Power Line Carrier Communication (PLCC) is a technology that facilitates the transmission of data over existing electrical power lines. By superimposing high-frequency signals onto low-frequency power lines, PLCC allows communication without the need for additional wiring. This method is cost-effective and efficient, making it increasingly popular in modern power systems.
Working Principle of PLCC
PLCC operates by modulating a high-frequency carrier signal onto the power line. This signal is then transmitted along the power cables, enabling communication between substations and equipment. Coupling devices are employed to ensure that the carrier signal does not interfere with the primary power transmission. The modulated signals can carry telemetry, control commands, and monitoring data effectively.
Applications of PLCC
PLCC is utilized in various applications, including:
- Telemetry: Collecting data from remote locations for monitoring and analysis.
- Protection: Implementing protective measures for electrical equipment.
