Introduction
Analysis of the core changes in the new version of the lightning location standard
| Technical dimensions | 2018 version | 2022 new version | Upgrade points |
|---|---|---|---|
| Terminology system | Define 14 terms | Reduced to 9 | Incorporate ground-to-ground/cloud-to-cloud terms into the referenced standard |
| Calculation formula | Derivation of the attached table | 4.2 Method definition | Standardization of NG and NSG calculation formulas |
Technical requirements for key equipment
The use of lightning sensors must meet the following requirements:
- Dynamic range: 5kA-300kA lightning peak current measurement
- 50% confidence ellipse center axis error≤0.5km
- Annual average effective working time of the station network ≥90%
Implementation case of data center buildings
Guiding case based on Chapter 4 of the standard: an IDC park in Beijing (0.5km²)
| Parameters | 2020 data | Calibration results |
|---|---|---|
| Observation period | 2009Depression2020 | Data has passed verification |
