After completing this video, you will understand the details related to:
1. Inspection and Maintenance:
Regular inspection and maintenance are critical to the effectiveness of a lightning protection system. These procedures ensure that the system meets the required standards, all components are in good condition, and any recent modifications are properly integrated. By conducting thorough inspections and maintenance, you can enhance the system's performance and minimize the risk of lightning-related damage.
2. Key Stages of Inspection:
Testing a lightning protection system involves different stages of inspection. These stages include: During Construction or Installation: Inspecting the system during the construction or installation phase ensures that the proper procedures are followed, especially for concealed components.
After Installation: Once all the components are installed, a comprehensive inspection and testing should be conducted. This includes checking electrical continuity, ensuring equipotential bonding, and examining the entire lightning protection system.
Periodical Inspection: Regular inspections, at least once a year, are essential to ensure ongoing compliance with standards and the effective functioning of the system.
Inspection Post-Alteration or Repair: After any modifications or repairs, a thorough inspection of the entire system is necessary to ensure its continued correct operation.
3. Key Tests in Lightning Protection System Testing:
To evaluate the performance and reliability of a lightning protection system, specific key tests must be conducted. These tests include:
Visual Inspection: A visual inspection ensures that the system meets the relevant standards and that all components are in good condition. Paying attention to specific details, such as loose connections, corrosion, and damage, is crucial.
Continuity Testing: This test verifies the connections between conductive components to ensure they are properly established. It ensures the continuity of components like down conductors, which are not easily visible during inspection.
Earth Resistance Test: The earth resistance test measures the resistance of earth electrodes in the system. It is vital to ensure electrical safety and should not exceed 10Ω.
SPD Testing: earth resistance test without visual indicators need to be tested to ensure their proper functioning. Follow the guidelines provided by the manufacturer for accurate testing.
Hence, how to test a lightning protection system is crucial for ensuring the safety and reliability of your structure. By following the recommended inspection and testing procedures, you can confidently protect your property from lightning strikes. Remember to conduct these tests in accordance with the applicable standards and seek the assistance of competent or authorized engineers when necessary.

Yes, what the best explaination..
Thanks!
Glad you liked it.
Very amazed
Thanks!
Nice VDO, but please remove that part where a hammer is used on a screw, (a very normal practice in India, which exposes the level of our knowledge for the very basic fitting techniques)
Thank you for your input! Typically, we operate with a drilling machine. In this particular video, we've incorporated both tools, though we generally do not recommend using a hammer.
Informative Video, well presented.
I have a basic question regarding the Continuity test. My doubt arises since I don't know the construction of an ESE device and its internals.
If I keep a multi-meter probe at the pointed tip of an ESE arrestor, and another probe at the base of the tall rod, below the ESE device, should I expect continuity? ( Am wondering because if there is an insulating air gap inside the dome, then I may not expect continuity. Right?)
Thank you for your appreciation, it means a lot!
Continuity will be there as our ESE is designed to transfer lightning current in the ground.
I have welded 2 rebars together Lap welding 40cm. Do I need to check the resistance between the rebars welded. if yes how much should be its value?
Hi Vimal, first, you need to make sure whether 40 cm is sufficient or not for overlapping. As per the IEC 62305 standard, 20 times overlapping is required against the diameter of the rod. So yes, you need to check the resistance between the rebars welded and the resistance value should be 0.2 ohms.
Can you explain how ESE device work?
