Overview

As an important part of smart grid construction, the intelligent distribution network faces the huge challenge of how to quickly and accurately locate the faulty section in case of line faults, especially small current grounding faults. The existing distribution network automation, feeder automation, and traditional fault location technologies have a series of problems such as high investment, the need for power outage construction, and accuracy. The intelligent distribution grid line status monitoring system launched by Barcelona Electric can accurately detect the type of line fault and quickly locate the fault section through precise measurement and adjustment of line current recording, thereby shortening the response and processing time of line faults and improving power supply reliability.
The intelligent distribution network line status monitoring system is an innovative intelligent monitoring product for distribution lines. The unit is the core sensing unit of the system, which is suitable for overhead lines in the 0KV distribution network. Relying on innovative small current self tapping technology and wireless communication technology, the unit can report monitoring data in real time, allowing power workers to grasp the line conditions at any time. With the help of comprehensive analysis technology for distribution network lines that is better than big data, the intelligent distribution network line status monitoring system can analyze lines including line faults, line loads, power quality, etc., providing comprehensive and reliable data support for optimizing the distribution network structure.
