In normal conditions there is in the atmosphere a balance between positive and negative charges, where the ground is more negatively charged than the air and the elements placed on the ground.

 

However, the formation of storm clouds creates a charge polarization: usually, the lower part of the cloud is charged negatively, inducing then a positive charge at the ground and other elements on it. The electric field at the atmosphere can reach then 10s of kilovolts.

 

This positive charge becomes more evident at metallic elements, pointed objects and well-earthed objects, including trees.

 

When the electric field is high enough, the cloud starts discharging towards the ground. The path formed by this discharge is called “downward leader” and produces a very sharp variation of the electric field, causing then corona effect.

 

One of these objects will be the one forming the upward leader, which will move towards the downward leader thus forming the discharge path between the cloud and the ground. This object will receive the lightning strike. The cloud charge will search the straightest path to earth. If this path is not controlled, damages can be severe.

 

Electrical effects: equipment destruction. Ground voltage rises and surges can damage all the equipment connected to the electrical network.

(1) Electrodynamical effects: Building damages. Conductors are submitted to mechanical strengths for being placed inside a magnetic field originated in another conductor. They may cause deformations and rupture.

(2)Thermal effects: Fires. Heat dissipation by Joule effect can even cause fires.

(3) Effects on living beings: electrocutions and burns. Currents passing through during a short lapse are enough for electrocution risk by respiratory or cardiac arrest. Further burn risk appears. (4) Induction effects: within a variable electromagnetic field, induced currents appear in every conductor. If these conductors are connected to computers or other electronic equipment, damages can be severe. The consequences of all these effects are important economical losses because of the damages in buildings and equipment due to lightning strike or fires caused by a discharge. Costs can be also very high if lightning causes service interruptions, stops production processes or forces to switch off and on again certain machinery if the control equipment is affected by lightning.

This object will receive the lightning strike. The cloud charge will find the most direct path to earth. If this path is not controlled, damages can be severe.

  • Brand: LPI

LPI Lightning Protection System & the need of safety lightning is one of the most devastating natural phenomena. There are many discharges during lightning storms and some of them caneven reach hundreds of kilo amperes. The electrical discharges are a great hazard to people, animal, buildings and electronic equipments. The economic consequences of lightning are also very important; it can cause fire, stop production of a factory or interrupt critical processes. A direct lightning discharge lasts a very short time but the intensity is enough to provoke electrocution resulting in heart failure andcausing burns of different degrees to the human beings. Lightning is a constant hazard where the buildings and equipments are becomingmore complex and sensitive every day. One lightning strike discharge can damage the buildings and cause failures to the electronic devicesinside the building and sometimes it may even results in fire and important economical losses.Until now, there is no device that can prevent lightning formation or lightning strikes. However, it is possible to create a path (divert) forthe lightning discharge to the ground which will minimise the damage to the environment through a well designed Lightning ProtectionSystem (LPS).

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 kiloamperes.

These electrical discharges are a great hazard to people, animals, buildings and electronic equipment. The economic consequences of lightning are also very important; it can cause fire, stop production of a factory or interrupt critical processes. A direct lightning discharge to a person results in current flowing through the body. This current lasts a very short time but the intensity is enough to provoke electrocution resulting in heart failure and causing burns of different degrees.

Until now, there is no device that can prevent lightning formation. However, it is possible to create a path for the discharge to ground of lightning that minimizes damage on the environment: the Lightning Protection System.

The need for lightning protection should be considered preferably during the first phases of the structures design. A Lightning Protection System has 4 basic objectives: 1) Capture lightning. 2) Conduct lightning current to earth avoiding damage. 3) Disperse lightning current in the ground quickly and safely. 4) Avoid the secondary effects of lightning (overvoltages).

Lightning Protection System

As one of the leading companies in the field of lightning protection, LPI has invested heavily in field and laboratory testing as part of its ongoing commitment to research and development. Throughout the product development of the Stormaster ESE, the proto-type models were subjected to intense testing under high voltage conditions. Following further refinements, the Stormaster terminals were subjected to final testing by an independently accredited test laboratory which completed testing in full compliance with the French National Standard NF C 17-102 (2011). The final testing of Stormaster ESE terminals showed effective performance as defined in this Standard.
