Distributed Fault Monitoring Device for Transmission Lines (Non-contact Type)

Fault Monitoring Device (non-contact type) for transmission lines is installed on towers, without contacting the high-voltage conductors. It uses dual solar panels and dual battery storage, ensuring continuous operation for 30 days even in rainy or cloudy weather. It is free from conductor current limitations, making up for the shortcomings of contact-type fault monitoring devices. It also provides accurate fault point location, fault type identification, automatic fault information generation, and alarm via SMS or WEB. The difference is that contact-type devices can distinguish fault phases, while non-contact devices only provide fault point location and fault type; fault phase information is provided by substation protection. The device can be connected to local lightning monitoring systems and meets security access requirements, providing technical support for improving line inspection efficiency and shortening fault recovery time.
