Lightning Arrester

Lightning Energy

Lightning is a capricious, random and unpredictable event. Its' physical characteristics include current levels sometimes in excess of 200 kA and speeds approaching one third the speed of light. Globally, some 2000 on-going thunderstorms cause about 100 lightning strikes to earth each second.

Because of its heavy investment in equipment (towers, electronic equipment, and satellite dishes), lightning is a major concern for the industry. A broadcast tower, typically the tallest structure in its area, is a prime target of lightning. If your tower or other facilities are a target of lightning strikes, the lightning will destroy your tower as well as the electronic system inside the tower. To avoid these unwanted effects, you should evaluate your lightning protection system.

Lightning is a product of electrically charged storm clouds. The charged clouds induce an opposite charge (ground charge) on the surface of the earth beneath it as they travel through the atmosphere. When the ground charge reaches a structure, the cloud charge pulls it up onto the structure, concentrating the ground charge on and around it. If the ground charge builds to a level exceeding the dielectric (insulation resistance) of the intervening air, an arc or lightning strike will occur. The process begins with stepped leaders branching down from the clouds. When they come within close proximity to the ground, approximately 500 feet, the electric field intensity at ground level becomes so strong that objects and structures begin to break down electronically, shooting streamers up toward the stepped leaders. When a streamer and a stepped leader connect, a path is created for a lightning strike.

The phenomenology of lightning strikes to earth, as presently understood, follows an approximate behavior:

1.The downward Leaders from a thundercloud pulse towards earth seeking out active electrical ground targets.

2. Ground-based objects (fences, trees, blades of grass, corners of buildings, Towers, lightning rods, etc., etc.) emit varying degrees of electric activity during this event. Upward Streamers are launched from some of these objects. A few tens of meters off the ground, a "collection zone" is established according to the intensified local electrical field.

Lightning is one of the most devastating natural phenomena. There are many discharges during lightning storms and some of them can even reach hundreds of kilo amperes. The electrical discharges are a great hazard to people, animal, buildings and electronic equipments.

Until now, there is no device that can prevent lightning formation or lightning strikes. However, it is possible to create a path (divert) for the lightning discharge to the ground which will minimise the damage to the environment through a well designed Lightning Protection System (LPS).

Kirkas design, manufacture & implementation of LPS (Lightning Protection System) in accordance to IS/IEC 62305 standard.

To protect a solar farm from lightning strikes

Solar farms are just big fields covered with conductive material. They are almost vulnerable for a lightning strike, which can damage or destroy solar panels, inverters and other critical equipment. So its no surprise that lightning activity and surge-related over-voltage abnormalities are identified as leading causes of solar project downtime.

The good news is solar owners and developers can protect their investment from the fallout of lightning strikes. Engineers at Topbas Grup, a global manufacturer and installer of grounding and other lightning protection technologies, have identified methods to bolster a projects ability to withstand lightning-related hazards.

While there is typically no code requirement for solar farm owners to install lightning protection, there are internationally recognized standards and methods to determine the requirement of lightning protection systems, and its a bright idea to take action.

Lightning is a common cause of failures in photovoltaic (PV) and wind-electric systems. A damaging surge can occur from lightning that strikes a long distance from the system, or even between clouds. But most lightning damage is preventable. Here are some of the most cost-effective techniques that are generally accepted by power system installers, based on decades of experience. Follow this advice, and you have a very good chance of avoiding lightning damage to your renewable energy (RE) system.

Lightning Rods

Lightning rods are static discharge devices that are placed above buildings and solar-electric arrays, and connected to ground. They are meant to prevent the buildup of static charge and eventual ionization of the surrounding atmosphere. They can help prevent a strike, and can provide a path for very high current to ground if a strike does occur.

Early streamer emitter (ESE) type lightning air terminals can protect a solar farm. The Umbraeco ESE terminal provides large protection zones as per National French standard NF C 17-102 (2011).

This configuration provides necessary protection zones, effectively dissipating lightning energy to the ground and helps to insulate the solar panels and inverter stations from damage. The other benefit of this system is that there will likely be significantly lower cost of labor and material to install the entire system as compared to a traditional Franklin rod system.
