These potentials are referred to as: Elements of a Lightning Protection System. In the resulting calculation, if the risk is found to be less than 1: Traditional taper-pointed air terminals are not as frequently used today but when they are they should be positioned near those points where a strike is most likely to hit the building.

The low impedance materials are required to ensure that the lightning energy will flow safely to the ground. These should be a minimum of 9 metre for the whole system. Since no part of the roof should be more than 5m from the nearest horizontal conductor, a 10m x 20m lattice is generally used on large buildings. If exposed metalwork such as pipes or ducts etc.

There are differences in the design limits applying to consumer installations and to supply industry installations and reference should be made to the correct standard to check the limits which apply in each situation.

The function of this device is to only connect the earths should the voltage between them rise above a certain value. The most important difference is that the earthing system is designed to ensure that potentials in its vicinity are below appropriate limits. Elements of a Lightning Protection System In general materials used for a lightning conductor are high purity copper or aluminium of a similar grade to that used in electrical conductors.

Internal bonds can however be of smaller cross section since they are mainly for equipotential purposes and are unlikely to carry a earthnig of the lightning current. Down Conductors The purpose of the down conductor is earghing provide the low impedance path from the air termination system to the earth system.

Earthing The various standards for earthing provide design limits to be met and together with codes of practice explain how the earthing system can be designed to meet these.

To do this properly the lightning protection system must capture the lightning, lead it safely down to earth, and disperse the energy within the ground. In their dedicated workshop, using a combination of high tech machinery and skilled staff Kingsmill Earthing have the ability to engineer or modify product items to your exact requirements.

Lightning Protection & Earthing – A Brief Guide By Kingsmill Earthing

The various standards for earthing provide design limits to be met and together with codes of practice explain how the earthing system can eagthing designed to meet these. Whether or not a building needs a lightning protection scheme depends on several factors. Kingsmill aim to provide the highest standard of Earthing and Lightning Protection Products: However, where this is not desirable for technical reasons, an earth potential equaliser can be installed between them.

There is typically one down conductor for every 20m or part thereof the building perimeter at roof or ground level. A number of factors will determine whether or not a person experiencing any of these potentials will be at risk, and the standards attempt to take these into account to ascertain the limits below which the design will be considered acceptable.

The earth electrodes being positioned near the equipment where a fault current was expected to pass. In general materials used for a lightning conductor are high purity copper or aluminium of a similar grade to that used in electrical conductors. These are sometimes PVC sheathed copper earth tapes for aesthetic purposes only. See – Copper Earthing Mats Lattice For Combatting Step Potentials Problems ii Touch Potential the potential difference during fault conditions between kingsmlll metalwork and a point on the soil surface iii Transfer Potential the potential difference between as insulated cable connected to a remote earth reference and the earth rod A number of factors will determine whether or not a person experiencing any of these potentials will be at risk, and the standards attempt to take these into account to ascertain the limits below which the design will be considered acceptable.

If this potential difference was greater than the breakdown value of the air or material in between, then a side flash could eartning resulting in severe damage. Finally, it is usual for the lightning protection system and main power earths to be interconnected.

The ring conductor is made from copper tape or cable aluminium is not permitted for use below ground and also helps to provide potential equalisation at ground level, in addition to potential grading.

Kingsmill Earthing have been manufacturing excellence since If the building is above 20m in height or of an abnormal risk this distance should be reduced to 10m. Kingsmill products are designed, manufactured and tested to meet rigorous standards ensuring high levels of safety and protection for buildings, people, livestock, content and sensitive electronic equipment. This is to ensure that side flashing does not occur.

Soil resistivity The external dimensions of the structure including any adjacent structures that are electrically connected The flash density in thunderstorm days per year for the area The type of construction Height above sea level Proximity of other structures such as tall trees The length of any overhead cables entering the structure.

For instance, if the building is an explosive store then the highest level of protection will be required even if the risk of a strike is low. An important element in the design of a lightning protection system is the consideration of bonding of exposed metalwork on or near the structure.

However, this needs to be assessed in relation to the consequences of a direct strike. This should be at least 0. Kingsmill Industries UK Ltd are a leading manufacturer and supplier of earthing materials and lightning protection products for the UK and international markets. Kingsmill are proud to be a UK owned, family run business, located in the heart of the UK and are pleased to say that they have been supplying excellent service into the industry for the last 15 years. From a simple modification to a complete new bespoke item.

The code of practice for Protection of Structures against lightning details kingsmmill and are used to estimate kingsmilk. History of Kingsmill Earthing. Since their inception inKingsmill have gone from strength to strength and have developed into one of the industry market leaders – Kingsmill have done this by focusing on service, quality, price, exrthing, commitment and trust.

Where practical they should be routed directly from the air termination kingsmull the earth system and be spaced symmetrically around the outside walls of the structure. Any good conductor which forms part of the building structure can be employed as a down conductor with appropriate connection to the air termination and earthing systems. The purpose of the eartihng conductor is to provide the low impedance path from the air termination system to the earth system.
