Lightning is a divine act, yet it puts lives and property at risk. It is unavoidable. Furthermore, whenever lightning strikes electricity lines, telephone lines, or perhaps even plumbing pipes, it sends current through the routes and pipes, which means that if someone is using a phone, an electric appliance, a plumbing fixture, or, even worse, is in the bath, they will presumably be struck and may get serious injuries or, in the worst case scenario, die.

Another worst-case situation is that lightning strikes can sometimes cause objects to catch fire or even explode. Once more, this may be the result of the secondary impact of striking a tree or other tall object.

There is currently no known way to stop natural occurrences like lightning strikes, flashes, or discharges. Measurement and management of the lightning danger are the only options.

Market Reports:

Despite the low likelihood of getting hit by lightning, 243 individuals are wounded and around 27 deaths occur each year as a result of being struck. Of course, a lot of people look for cover during thunderstorms. Constructions and other structures are more susceptible to being hit, which is not unexpected.

Witnesses may catch a glimpse of snow, ice, or rain falling throughout a storm. However, they miss the collision of these identical particles within the storm clouds, which worsens the disparity between the ground and the clouds.

Ground objects acquire electrical conductive properties, enabling current to flow between them and the stormy clouds' negative electrode. This causes the stormy clouds' opposite charges to fall to the earth's surface.

According to an examination of the electromagnetic fields produced by lightning, there are tens to hundreds of lightning strikes on earth per second. Researchers were more concerned with cloud-to-ground flashing regarding lightning protection for electrical equipment.

Because of this, lightning protection measures are crucial. Hence, implementing lightning protection system designs is standardized by NFPA 780 and IEC 62305 standards to protect individuals and assets from lightning-related risks. 

The Most Recent Release Of NFPA 780: 

2017 saw the release of the most recent versions of the NFPA 780 Standard for the Implementation of Lightning Protection System Design.

The paper addresses the protection of, and installation specifications for, conventional lightning protection system designs for a variety of structures, including both regular buildings and complexes that hold explosive materials. Additionally covered are any boats, windmills, airfield lighting circuits, solar arrays, and any other related collecting systems.

To the extent that they include conductors, comprising interconnecting conductors, strike termination devices, surge arrester audits, rooting electrodes, and other connections and fittings, lightning protection conductors are deemed to be complete systems within the principles of this standard.

The 2017 version includes new specifications for on-site examinations of finished lightning protection system installations. The entity having jurisdiction was required to conduct periodic testing and/or inspections to ensure compliance.

The Purpose Of Lightning Protection For Electrical Equipment:

The purpose of a lightning arrester audit is to shield electrical power systems and telecommunications conductors and insulation from lightning's potentially harmful effects.

A standard lightning arrester features a ground terminal as well as a high-voltage output. Electricity from a lightning flash is deflected through the arrester and onto the soil when it passes through a transmission line to the lightning arrester audit.

Thousands of kilovolts are released when lightning strikes the electrical system if protection is ineffective or nonexistent, which may harm transmission lines, transformers, and other electronic or electric devices. Because lightning creates an extremely high voltage that fastens on incoming power lines and might harm electrical equipment, it is crucial to the operation of a lightning arrester.

Lightning can be released into designated earth trenches or ground using a lightning protector, an arrester, or an air node, leaving behind other conducting channels and buildings. It is the facility owner's or the relevant department's obligation to ensure workplace safety.

In this situation, the employer must either build an appropriate lightning protection system designed to reduce lightning hazards or verify that the installed air terminations provide the necessary level of lightning protection. 

Only 50% of the lighting stimulus will go straight to earth; the other 50% will flow through the pass bond onto the inbound panel and out into the electronic systems in the installation, which is why lighting protection is required by law. Any industrial installation's equipment and personnel are severely in danger as a result of this.

By attempting to address the conventional setup of lightning protection systems for common and special occupancy rates, in addition to the following special structures: structures housing explosive materials, heavy-duty stacks, airfield lighting circuits, solar arrays, watercraft, wind turbines, and structures containing flammable gases or liquids that give off flammable vapours, NFPA 780 contributes to reducing disastrous events like these.

Lightning Protection System Design:  

The Lightning Protection System Design is a crucial component of any construction. We hope we have covered the details of the likelihood of lightning strikes, lightning features, and the parameters that arise from modelling lightning strikes' consequences.

Engineers must adhere to the highest standards when creating lightning protection systems for any structures, namely NPFA 780 or a specification that is appropriate for the location of the building or infrastructure. 

It is crucial to guarantee complete compliance when constructing these installations for public buildings, and there is no greater way to achieve this than by obtaining a UL Lightning Protect System Master Tag.

Not only will this show a dedication to safety, but it will also guarantee that the system will function in the case of a lightning strike!
