VOLTAGE & CURRENT UNBALANCE – A Primer

Unbalance is a serious Power Quality issue affecting mainly low-voltage distribution systems in commercial and industrial facilities. Voltage unbalance is responsible for low performance and shortens life span of three-phase motors among other consequences. What then is voltage unbalance? Voltage Unbalance Voltage unbalance is the measure of voltage difference between the phases of a three-phase […]

How PQ Best Practices Can $ave You Money

The fact that lots of money is being lost through poor Power Quality (PQ) in facilities across the world need not be overemphasized. Electric Power Research Institute (EPRI) in 1995 reported that the cost attributable to poor PQ in US represents a large annual cost to the economy estimated at the cost of 100 billion […]

Saving Energy Costs– A Close Look At Hotels

In hospitality business energy is the blood and life. Without energy hotels seize to be so called. From Lighting Lifts, Air-conditioner & Ventilation, Heating & Catering to Leisure & Fitness, are all services relying on constant supply of energy. Energy use in hotels account for between 6 – 8% of operating profit worldover. However, in […]

HOW YOU CAN SAVE ENERGY – Using Power Quality Techniques

Worldover, from manufacturing, utilities, production, offices to services. Energy is an essential raw material. Its costs a major critical issue in production of goods and services. However, energy costs are escalating and not likely to go down, businesses are grasping on the best ways and means of cutting cost in their bid to remain competitive. […]

Earthing & Lightning Protection – The FullSpectrum Advantage

Earthing & Lightning (including Surge) Protection has become more critical in the Electrical Power infrastructure in today’s business. With the prolification of electronics in organizations for efficiency, it has brought the subject to the front burner of reliability, profitability and productivity. It is no longer only important to supply Power but the Quality of Power […]

What Do I look out for in Quality Surge (Transient Overvoltage) Protectors?

There is a deluge of products claiming to protect Electronic equipment against Lightning and Surges (transient overvoltage). 95% of them are sub-standard, misleading and of no effect. However, when subjected to tests, many of them have an unacceptably high let-through voltage. The wrong let-through voltage is disruptive and harmful to your electronic equipment. This is […]

What, Where and Why Should I Protect Electronic Systems Against Surges

Structural lightning protection to BS EN 62305 is designed to protect the fabric of the building against lightning damage. It is not intended to, and will not, protect electronic equipment against the secondary effects of lightning. The term ‘electronic equipment’ means any piece of equipment which incorporates sensitive electronic components; computers, telecommunication equipment, PBX, control […]

Lightning Protection System Integrity Checks – You Must Do at Least Yearly

The importance of Inspection, Testing, Recording and Maintenance of a lightning protection system need not be overemphasized. An effective lightning protection system should Intercept, Dispense and Conduct Safely the lightning energy to the ground without affecting the structure and the systems within. The code BS EN 62305 adequately details the requirement for inspecting a lightning […]

How Do I Calculate Earth Electrode Resistance For Different Systems

In designing an effective earthing system, be it for commercial or industrial, the sole aim is to achieve a low earth resistance and doing that doesn’t need to cost you an arm or a foot. You have to carry out a soil resistivity test among other things. Once the soil resistivity has been measured from […]

Making Numerous Connections of Different Conductors – FurseWELD (Exothermic Welding II)

In many construction projects, there arises the need to connect like or different conductors. Electricity for welding is unavailable, clamps may likely fail and the need for continuity is paramount. FurseWELD comes very handy, cheap and the joint made is rigid and continuous. Applications include but not limited to the following; Earthing for power plants […]
