Figure 1: What data does a digital lightning protection system need to monitor?

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 should we talk about data first?

The core of digital lightning protection is not the number of devices, but the data capabilities.

If the system only sees a count or switch status, it will be difficult to support risk judgment, accident tracing, and closed-loop operation and maintenance.

2. Lightning strike and surge event data

Lightning strike and surge event data include occurrence time, number of events, impact intensity, affected objects and persistence characteristics.

These data are the basis for accident tracing and life assessment.

3. SPD and grounding status data

The SPD status is used to determine whether the protection device is still effective, and the grounding status is used to determine whether the discharge path is reliable.

The two must be viewed in conjunction.

4. Equipment, environment and operation and maintenance data

Equipment anomalies, environmental changes, and operation and maintenance disposal are important contexts for understanding the causes of risks.

Without this context, lightning protection data can easily become siled numbers.

5. Data must be related to each other

Digital lightning protection is not about data stacking, but about establishing correlations.

The ability to judge can only be achieved when links are formed between events, status, trends, and dispositions.

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.
