Introduction

In-depth analysis of technical specifications for lightning protection device testing of wind turbines

Test items	Requirements	Test methods
Blade lightning protection device	- The number of lightning terminals meets the design requirements - The material specifications meet the requirements of Table 1 - Reliable fixation, cross-sectional area ≥50 mm²	1. Check that the number of lightning terminals is consistent with the design 2. Measure the material and cross-sectional area of the lightning terminals 3. Check the reliability of fixation
Cabin lightning protection device	- The material of the lightning terminal meets the requirements of Table 1 - The material of the down conductor meets the requirements of Table 2 - Transition resistance ≤ 0.24Ω	1. Check that the lightning arrester is consistent with the design 2. Measure the cross-sectional area and transition resistance of the down conductor 3. Check the connection reliability

Explanation of professional terms and practical applications

Surge protective device (SPD): A device used to limit transient overvoltages, installed in electrical systems to protect equipment from lightning strikes. For example, in the power distribution cabinet of a wind turbine, the SPD must comply with the requirements of GB/T18802.1 and GB/T18802.21, and its status indicator must be checked regularly to see if it is normal.
