The most important difference is that the earthing system is designed to ensure that potentials in its vicinity are below earrhing limits. If this potential difference was greater than the breakdown value of the air or material in between, then a side flash could occur resulting in severe damage. From a simple modification to a complete new bespoke item. Elements of a Lightning Protection System.
The principal parts are detailed below. The purpose of the down conductor is to provide the low impedance path from the air termination system to the earth system. However, this needs to be assessed in relation to the consequences of a direct strike. In general materials used for a lightning conductor are high purity copper or aluminium of a similar grade to that used in electrical conductors.
Lightning Protection & Earthing – A Brief Guide By Kingsmill Earthing
These should be a minimum of 9 metre for the whole system. Eartbing are sometimes PVC sheathed copper earth tapes for aesthetic purposes only. For external bonds the cross section of the bonding material should not be less than that of the main conductors. An important element in the design of a lightning protection system is the consideration of bonding of exposed metalwork on or near the structure.
Kingsmill Earthing have been manufacturing excellence since Finally, it is usual for the lightning protection system and main power earths to be interconnected. Where practical they should be routed directly from the air termination to the earth system and be spaced symmetrically exrthing the outside walls of the structure.
Kingsmill Earthing, Lightning & Surge Protection
Whether or not a building needs a lightning protection scheme depends on several factors. Traditional taper-pointed air terminals are not as frequently used today but when they are kingsmlll should be positioned near those points where a strike is most likely to hit the building. For this reason, the earth termination should be bonded to the rest of the earth electrodes.
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. The code of practice for Protection of Structures against lightning details these and are used to estimate risk. In the past, it was normal practice to design an earthing system to achieve kingsmill certain impedance value.
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. Recently, this has changed towards the approach used in North America.
See – Copper Earthing Mats Lattice For Combatting Step Potentials Problems ii Touch Potential the potential difference during fault conditions between exposed 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.
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. Kingsmill thrive on solving customer products problems. 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.
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. These potentials are referred to as: For down leads not part of the structure, copper earth tapes and aluminium earth tapes are the most widely used materials.
This commitment to quality follows throughout all aspects of the company including manufacture, development, customer support and service. This is to ensure that side flashing does not occur.
This should be at least 0. Each down conductor should also be kinvsmill with a test point as a means of isolating the earth electrode for test purposes. The most common terminations are copper earth rods driven into the ground.
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. The low impedance materials are required to ensure that the lightning energy will flow safely to the ground.

History of Kingsmill Earthing. Internal bonds can however be of smaller cross section since they are mainly for equipotential purposes and are unlikely to carry a proportion of the lightning current. Down Conductors The purpose of the down conductor is to provide the low impedance path from the air termination system to the earth system.
The earth system should be designed as a whole since the complete installation should rise in potential together, to avoid excessive voltage differences. In their dedicated workshop, using a combination of high tech machinery and skilled staff Kingsmill Earthing have the ability ezrthing engineer or modify product items to your exact requirements. 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.
Go back to blog index. The function of this device is to only connect the earths should the voltage between them rise above a certain value. Earghing aim to provide the highest standard of Earthing and Lightning Protection Earthingg If the building is above 20m in height aerthing of an abnormal risk this distance should be reduced to 10m. 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.
