This article is a knowledge article that continues the digital lightning protection series.

The pictures in this article have been re-conceived independently according to the article's theme. All pictures are centered around the knowledge points of this article, and cross-article general templates are no longer used.

1. Why is it often difficult to explain clearly after an accident?

At many sites, after the equipment is damaged, they start to ask whether it was a lightning strike, whether the SPD is effective, and whether the grounding is normal.

Without event records and status files, these issues can only rely on empirical judgment.

2. What should be recorded in the event file?

The event file should record the lightning surge event, as well as the SPD status, grounding status, equipment alarms and on-site disposal before and after the event.

It is not a running account, but a chain of data evidence of the risk change process.

3. Why must operation and maintenance form a closed loop?

Finding an exception is only the first step. The key is whether someone handles it, how to handle it, and whether to review it after handling it.

There is no closed loop. The system only detects problems and does not complete management.

4. How do event files support management?

Event files can support site profiling, risk classification, spare parts management and responsibility tracing.

In the long run, it will become a healthy record of the lightning protection system.

5. How does micro-IoT understand closed-loop value?

The end point of digital lightning protection is not one more alarm, but the formation of a closed management loop of sustainable improvement.

Events are recorded, status is judged, alarms are handled, and results are reviewed.

Conclusion: From single point protection to long-term status management

The core of digital lightning protection is not to rebrand traditional lightning protection, but to move the lightning protection system from static installation to long-term status management.

When events, status, trends and actions can all be recorded, the lightning protection system truly has the ability to continuously improve.

Micro-IoT technology will continue to share content related to intelligent lightning protection, electrical safety early warning, digital power distribution, energy supervision and industrial Internet of Things.

Micro-IoT/FEXLINK uses data to reconstruct energy efficiency and electrical safety.

Where there is electricity, there is micro-IoT.
