At all times consideration must be given to the possibility of side flashing. Go back to blog index. An important element in the design of a lightning protection system is the consideration of bonding of exposed metalwork on or near the structure.

In the past, it was normal practice to design an earthing system to achieve a certain impedance value. Each down conductor should also be provided with a test point as a means of isolating the earth electrode for test purposes. However, where this is not desirable for technical reasons, an earth potential equaliser can be installed between them.
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. These are sometimes PVC sheathed copper earth tapes for aesthetic purposes only.
If the building is above 20m in height or of an abnormal risk this distance should be reduced to 10m.

Kkingsmill a simple modification to a complete new bespoke item. 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.
History of Kingsmill Earthing. 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. 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 code of practice for Protection of Structures against lightning details these and are used to estimate risk.

Down Conductors The purpose of the down conductor is to provide the low impedance path from the air termination system to the earth system. 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.

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 earthint 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.
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.
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. The earth electrodes being positioned near the equipment where a fault current was expected to pass.
These potentials are referred to as: Kingsmill aim to provide the highest standard of Earthing and Lightning Protection Products: 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, delivery, commitment and trust.

This is to ensure that side flashing does not occur. Kingsmill Industries UK Ltd are a leading manufacturer and supplier of earthing materials and lightning protection products jingsmill the UK and international markets. 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. Finally, it is usual for the lightning protection system and main power earths to be interconnected.
Recently, this has changed towards the approach used in North America. 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.
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. In the resulting calculation, if the risk is found to be less than 1: In general materials used for a lightning conductor are high purity copper or aluminium of a similar grade to that used kingzmill electrical conductors. For this reason, the earth termination should be bonded to the rest of the earth electrodes.
For down leads not part of the structure, copper earth tapes and aluminium earth tapes are the most widely used materials. Elements of a Lightning Protection System. These should be a minimum of 9 metre for the whole system. The most common terminations are copper earth rods driven into the ground.
The purpose of a lightning protection system knigsmill to shield a building, its occupants and contents from these adverse effects.

earthiing This commitment to quality follows throughout all aspects of the company including manufacture, development, customer support and service. 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. 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.
The low impedance materials are required to ensure that the lightning energy will flow safely to the ground. There is typically one down conductor for every 20m or part thereof the building perimeter at roof earthimg ground level.
Internal bonds can however be of smaller cross section since they are mainly for equipotential purposes and kkngsmill unlikely to carry a proportion of the lightning current.
