Abstract: There are a large number of communication base stations and they are widely distributed. Many sites are located in mountains, rooftops, suburbs or wild areas, and are obviously unattended. Remote digital lightning protection monitoring can report lightning strikes, SPD status, grounding status and equipment alarms in a timely manner, reducing blind inspections and post-mortem inspections.
The biggest difficulty in lightning protection management of communication base stations is that there are many points, they cover a wide area, and they are difficult to see from a distance. Many sites are unattended, and operation and maintenance personnel may not always know what happened on site after a thunderstorm.
Base station power supply, transmission and communication equipment are relatively sensitive to surges. Once the lightning protection status is unknown, it is easy to have a passive situation of tracing after the failure.
1. Why is it easy for base stations to form lightning protection blind spots?
Base stations are distributed on rooftops, in mountains, in suburbs, and in the wild. The environments vary greatly and the exposure to thunderstorms is different. Manual inspection costs are high, and it is impossible to arrive at the station in time for inspection after every thunderstorm.
Without remote data, it would be difficult to determine if an equipment abnormality is caused by a lightning surge, SPD problem, grounding abnormality, or power quality problem.
2. What should be focused on during remote monitoring?
The base station should focus on lightning surge events, SPD status, grounding status, power supply abnormalities and communication equipment alarms. Only by correlating these data can we determine whether emergency dispatch is needed.
A single lightning strike count or trip signal is not enough to support a complete decision.
3. How to Reduce Blind Order Distribution
The remote platform can classify sites based on lightning strike intensity, protection status, grounding changes and equipment alarms. High-risk sites are prioritized, and low-risk sites are placed under observation.
In this way, operation and maintenance personnel no longer only rely on experience to arrange site visits, but decide the sequence of actions based on risk data.
4. What is the value of long-term data?
Long-term data can identify high thunderstorm areas, high-frequency fault sites, weak grounding points, and points prone to SPD degradation.
This information can support inspection plans, spare parts strategies and site modifications, allowing base station lightning protection to shift from passive maintenance to active management.
5. How does FEXLINK understand remote lightning protection monitoring of base stations?
FEXLINK believes that base station digital lightning protection must be centered on remote status visibility. The FEXLINK system should uniformly manage site lightning strikes, protection status, grounding status and work orders in a closed loop.
For decentralized sites, remote visibility is a prerequisite for management.
Conclusion: Remote status visibility is the basic capability of base station lightning protection.
The more base stations there are and the more widely they are distributed, the less we can rely on post-site inspections. Digital lightning protection enables decentralized sites to have event recording, risk classification and closed-loop operation and maintenance capabilities.
FEXLINK technology will continue to share content related to intelligent lightning protection, early warning of electrical safety, digital power distribution, energy supervision and industrial Internet of Things.
FEXLINK/FEXLINK uses data to reconstruct energy efficiency and electrical safety.
Where there is electricity, there is FEXLINK.
