SURGE PROTECTION. Why surges/transients overvoltages have become increasingly critical?
Imagine in a busy international airport like London, Heathrow. An online, real time business institution like Nigerian stock exchange, a major specialist hospital, oil production platform. Downtime of seconds, minutes, hours and days as a result of lightning strikes and surges. Putting off the transactions with enormous consequences like confusion, embarrassment, loss of revenue, […]
Energy Management
All nations, focused Nations are burdened by energy matters. Making energy and its management of vital importance in solving nations biggest challenges in the march towards energy efficient economy and growth. The challenges, the 3Es are; Environmental Quality- reducing global climate change and acid rain. Economic competitiveness – reducing costs and creating jobs. Energy […]
Performance Grounding (Earthing) and Wiring
Grounding (Earthing) and Wiring are the foundation and the pillar of all electrical power, communication or data processing systems. When this foundation is taken care of, the systems will be reliable and stable. With over 80% of power quality (PQ) problems traceable to improper wiring and grounding of systems, it is now obvious that this area […]
Energy policy and Economic development of Nations
Energy has become arguably the world’s most needed resource. An indispensable raw material in production, distribution of goods and services. However the escalating cost of energy, its sustainability, supply security and the drive for efficiency, to reduce or replace fossil fuel and save the environment has given impetus to energy management. All serious […]
Oil and Gas facilities …a total solutions approach against Lightning
While health, safety and environment are key priorities in the upstream, midstream and downstream sectors of the Oil & Gas industry. Unfortunately, it is also one of the most vulnerable industry when it comes to lightning related dangers. With heavy lightning intensity in Nigeria and West Africa of 140-180 thunderstorm days per annum compared with […]
Power Quality-an overview
Electric Power is perhaps the most essential raw material used across all sectors of the economy. It is an unusual commodity because it is required at a continuous flow. It cannot be conveniently stored in quantity. It cannot be subject to quality assurance checks before use like water. Just as poor water quality cause health […]
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? […]
LIGHTNING PROTECTION FAQ 3/5
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 […]
