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 […]
How to Make Easy, Cheap & Multiple Electrical Connections – FurseWELD (Exothermic Welding)
In most applications, where making large or small numbers of high quality, electrical connections are required. FurseWELD comes handy. They typically find applications in; Earthing for power plants and substations Telecommunications Transmission and power distribution lines Cathodic protection Rail connections FurseWELD is cost effective, simple, self-contained system that uses high temperature reaction of powdered copper […]
Mitigate Your Facility Expensive Downtime and Unnecessary Headaches – Quality Surge Protectors
Electronic systems have become central to virtually every aspect of our lives from PCs and building management systems in the offices to automated petrol pumps, barcode scanners at the supermarket, ATM’s in the banks and programmable Logic Controllers (PLC) in facilities etc. Lightning and electrical surges devastate these electronic systems that drive industries. Nigeria is […]
Power Solutions – Using Power Quality as a Tool
Poor Power Quality can be expensive and affect the bottom line in the workplace. The appropriate mitigation and elimination of probable problems with a proper understanding of power quality skills can save much. Best practices in early design is key to running seamless and cost effective operations. And will enhance productivity and profitability of your […]
Earthing (Grounding) and Wiring – Key to Electrical Power Issues
With the upsurge of electronics system prevalent today is virtually in all spheres of our existence and living. It introduces power quality issues affecting operations and performance of systems. The need to have a closer and proper look at Wiring and Grounding (Earthing) systems as a critical part of electrical infrastructure, determining to a large […]
A Major Facility Maintenance Concern – Poor Power Quality
The world of an engineer, particularly facilities maintenance engineer is simply a life of troubleshooting in the workplace. Some of the common concerns or experiences include computer lock ups, malfunction, misoperation or damage. Nuisance tripping of circuit breakers, relay and contactors. Sensitive equipment malfunctioning or crashing intermittently like Programmable logic controllers (PLC’s), adjustable speed drives […]
