Energy Auditing – Getting The Job Done 1

We are now all aware that energy audit or assessment is an inspection, survey and analysis of how energy is used in a building or facility. The sole aim being to conserve energy, achieve optimal efficiency and save costs without affecting the output. The next relevant and big questions are how do I get started? […]

Power Quality – An overview IV

Power Quality problems come with a lot of consequences and cost. Costing organizations millions of dollars, causing systems and equipment downtime with loss of productivity. The culprits are Lightning Utility Automatic Breaker Reclosure Utility Capacitor Switching Commercial high rises without enough distribution transformers Gen-sets not sized for harmonic loads Applying P.F correction capacitors without considering […]

Energy Audit – A Matter of Level (Type)

Before stating an energy audit, it is helpful to have some idea of the scope of the project and the level of effort necessary to meet expectations. Here we shall discuss  the levels of surveys and assessments necessary to perform commercial building or industrial audits.  American Society of Heating Refrigerating and Air conditioning Engineers (ASHRAE) […]

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 […]
