Power Quality – An overview III
Poor power quality affect electronic systems that drive automated processes in buildings and facilities.In as much as they enhance efficiency, they leave behind consequences at great cost.It is therefore, important to know what causes these problems in order to eliminate and mitigate these problems.Power quality problems are caused by environmental and weather conditions, facility […]
Energy Audit – The what and Why
Energy costs are increasing exponentially and not likely to drop. It has put many organizations and facilities on the edge wondering what to do. Energy management is the way out. How to effectively conserve energy, cut costs and start saving is the challenge. Of critical concern to organisations, are what immediate proactive steps to take. […]
Power Quality (PQ) – An Overview II
If your transformers, cables and neutrals overheat. When you experience voltage sags (dips), swells (overvoltages) or sudden increase in voltage in form of spikes, transients, glitches, surge and voltage unbalance among phases. Circuit breakers tripping, computer shutting down, high temperature in server rooms, motors burning, PLC misoperating or light flickering, you have a power quality […]
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 […]
