LIGHTNING PROTECTION FAQ 5/5
Q5.1. How do I obtain a good earth for a building constructed on rock? There is no simple or easy solution to this question. Local soil conditions will have a significant bearing on the result. Guidance is given in the BS EN 62305 for structures erected on rock. Q5.2. Is it dangerous to have a […]
LIGHTNING PROTECTION FAQ 4/5
Q4.1. What is step potential? Step potential is the voltage gradient difference measured in volts existing between the feet of a person standing on the ground. When a lightning strike reaches earth and is being dissipated in the soil, there can exist a difference in potential between a person’s (or animal’s) feet. Q4.Galvanized tape underground? […]

Q3.1. Non-metallic DC clips. Do they comply with the British / IEC Codes of Practice? The Code merely states that, where non-metallic fixing materials are used, and then consideration should be given to their possible degradation due to ultraviolet light, frost, etc. Quality clips are manufactured from a high- grade polypropylene which exhibits excellent mechanical […]
LIGHTNING PROTECTION FAQ 2/5
Q2.1. What is Radioactive Lightning Protection? Radioactive lightning protection is based on claims that a radioactive source around the head of an air terminal enhances its natural ion discharge which naturally takes place during a static build-up associated with lightning storms. This enhancement is claimed to be so great that it improves dramatically the ability […]

LOWERING EARTH’S RESISTANCE USING FURSECEM (MARCONITE)
What quantity is needed?By mixing FurseCEM and any Portland cement in right ratio of 3:1 you are creating a conductive concrete that will perform the magic. If the total amount of FurseCEM and cement mixture required for 1 cubic metre is 1300kg. (Re PMC conductive products brochure).Therefore, to make 1 cubic metre of conductive concrete, […]
LIGHTNING DAMAGE
PROTECTING YOUR OIL AND GAS INSTALLATIONS While safety is a top priority in the upstream, midstream and downstream sectors of the Oil and Gas industry, unfortunately it is also one of the most vulnerable when it comes to lightning related dangers. Despite these known problems and dangers associated to power quality lightning strikes and the […]
8 BENEFITS OF USING FURSECEM (MARCONITE) AS A GROUND ENHANCING SOLUTION
FurseCEM conductive aggregate offer a permanent and one-stop solution to difficult terrains. Where certain soil conditions require special treatment to achieve lowered Earth Resistance. FurseCEM advantages are: PERMANENT EARTH READINGFurseCEM conductive concrete has a resistivity that will remain constant over the life of the installation without the requirement for maintenance. CONSTANT VOLUMERegardless of water content. […]
EARTHING PROBLEMS – FurseCEM (Marconite) a permanent Solution
In most installations particularly in telecoms & ICT, Oil and Gas and process manufacturing. The risk of fire, explosion, fault and leakage currents affect Power quality. Hence the need to lower earth resistance for safe, optimal and proper equipment function.Certain ground conditions make these difficult despite massive deployment of earth electrodes .Without achieving significant results […]
