Lightning protection design standard requirements for energy storage systems

What is lightning protection level?

Lightning protection level is used to design protection measures according to the relevant set of lightning current parameters. Complete system used to reduce physical damage due to lightning flashes striking a structure. It consists of both external and internal lightning protection systems.

How does NFPA 780-2020 protect people from lightning?

To safeguard people and property from lightning-related hazards, NFPA 780-2020 standardizes the installation of lightning protection systems. During thunderstorms, many people seek shelter, and buildings and other structures are more likely to be struck.

What are the lightning protection requirements for roof mounted equipment?

Our interpretation of the lightning protection requirements can be summarized by the flow chart shown in Figure 4.28. a) If the roof mounted equipment is not protected by the air termination system but can withstand a direct lightning strike without being punctured, then the casing of the equipment should be bonded directly to the LPS.

Do I need an external lightning protection system?

Therefore the need for optimized and reliable electrical protection against the influence of lightning and surge events becomes mandatory. A risk assessment per IEC 62305-2 should first be performed to understand better if an external lightning protection system (LPS) is required.

Should lightning protection be NFPA 780 compliant?

Determining a way to implement a lightning protection system in accordance with NFPA 780 is a great way to alleviate the continual burden of being concerned about what could happen and what would need to be done if lightning did just happen to strike.

How should a lightning protection system (LPS) be connected?

These individual elements of an LPS should be connected together using appropriate lightning protection components (LPC) complying with BS EN 50164 or IEC 62561 series. This will ensure that in the event of a lightning current discharge to the structure, the correct design and choice of components will minimize any potential damage.
