1. Why digital lightning protection can be used as an entrance
Digital lightning protection solves the problem of high-energy impact, protection status and visibility of ground paths. These data themselves are electrical safety data. When this data is combined with distribution status, equipment alarms and environmental data, a more complete risk picture can be formed.
In park power distribution, building power, base station energy, photovoltaic power stations, data centers and industrial sites, lightning protection systems often do not exist in isolation. It is closely related to power supply, communications, grounding, equipment operation, on-site environment and manual operation and maintenance. If you only look at the status of a single device, it is easy to underestimate the risk, and it is also easy to encounter difficulties in tracing after a failure occurs.
It does not light up a certain anomaly, but understands on-site objects, event processes, status changes and disposal results in the same link. Only in this way will managers see not scattered alarms but an explainable risk structure.
Therefore, data definitions must be established simultaneously around the monitoring of lightning strike events, SPD status, grounding status, voltage, current, leakage, temperature and arc fault. Which ones are real-time status, which ones are historical events, which ones are trend indicators, and which ones are disposal results, all need to be unified coding and unified caliber at the platform level.
Therefore, lightning protection data, power distribution status, multi-dimensional characterization, risk diagnosis and early warning closed-loop should not be used as additional actions in the later stage of the project, but should be considered simultaneously in the scheme design stage. How to install equipment, how to report to the platform, how to handle it with personnel, and how to review the results all serve the same closed-loop goal.
2. Early warning requires multi-dimensional features
It is difficult to identify complex electrical hazards with a single threshold. Many risks do not exceed the action threshold in the early stage, but appear as trend changes, frequency increases, abnormal fluctuations and multiple indicators.
This requires voltage, current, leakage, temperature, arc, grounding and equipment status to participate in the judgment.
3. From single point alarm to unified diagnosis
Future systems should not separate lightning protection, leakage, temperature, arc and power distribution status, but should put them in a unified diagnostic framework.
In this way, a device alarm can be upgraded to a system-level hazard portrait.
The first level is status judgment. For example, whether a certain point is offline, whether the SPD is tripped, whether the grounding is abnormal, and whether the equipment alarms. This layer solves whether there are any problems.
The second level is trend judgment. For example, in the past period of time, whether there have been more lightning strikes, whether the grounding condition has continued to deteriorate, whether alarms have reoccurred, and whether the status has been restored after maintenance. This layer addresses whether the risk is developing.
The third level is correlation judgment. For example, whether the lightning strike event is adjacent to the equipment abnormal time, whether the SPD status change is accompanied by grounding abnormality, and whether the risk index drops after the work order is processed. This layer addresses reasons and priorities.
If the platform only makes first-level judgments, its value is relatively limited; if it can make trend and correlation judgments, digital lightning protection can be upgraded from an alarm tool to an operation and maintenance decision-making tool.
4. Why is device-cloud collaboration important?
Many risks require rapid identification on the device side, as well as long-term trend analysis and cross-site comparison in the cloud. The client side is responsible for real-time performance, and the cloud side is responsible for overall performance.
Device-cloud collaboration can make early warning both fast and in-depth.
5. How does FEXLINK understand the transition from lightning protection to early warning?
FEXLINK believes that digital lightning protection is an important starting point for early warning of electrical hazard detection. The FEXLINK system will start from lightning strike, SPD, grounding and other data and gradually extend to multi-dimensional electrical characteristic diagnosis.
The goal is not to make isolated monitoring points, but to form a data base for electrical safety and energy efficiency.
Conclusion: Starting from intelligent lightning protection and moving towards electrical safety data base
Digital lightning protection makes lightning protection status visible, and electrical safety early warning makes more hidden danger processes visible. When electrical signals are continuously collected, calibrated, analyzed and interpreted, electrical safety management can move from post-processing to early warning.
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.
