LIGHTNING PROTECTION …an insurance for your assets
Lightning contain awesome amount of electrical energy and even though it is of a very short duration. It leaves behind tremendous damage and destruction. The effects of a direct strike are obvious and apparent – buildings damaged, trees blown apart, personal injuries and loss of life. Lightning can cause fires, explosions, chemical release or mechanical […]
LIGHTNING SOLUTIONS FOR YOUR TELECOMS & ICT INFRASTRUCTURE
Every year, lightning and associated damages to telecommunications & ICT infrastructures run into billions of US dollars besides the loss of revenue, inactivity and production losses from industrial and business downtime. Lightning, Voltage Surges and improper Earthing are major power quality problems in telecoms & ICT facilities. Without warning lightning and electrical surges can devastate […]
HARMONICS
In commercial buildings and industries, engineers are confused as to why transformers overheat, while supplying average loads. Neutral conductors overheat from excessive loads, while the circuit is balanced. Circuit breakers tripping for no apparent reason. Yet all standard checks confirm everything is normal and ok. What then is the cause? – HARMONICS. Harmonics What are they? Harmonic […]
Voltage Disturbances
Voltage disturbances is a critical power quality issue today perhaps second only to earthing (grounding) & wiring in frequency of occurrence and devastating effects.Costing industries and businesses over hundreds of millions of dollars annually. Cost Per Dip for different sectors in euro (from case studied laboratory) Particularly hit are continuous manufacturing and high tech concerns. […]
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 […]
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 […]
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, […]
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 […]
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 […]
