Performance Wiring and Grounding (Earthing) – Basic Principles I
Wiring and Earthing (Grounding) are essential power quality (PQ) tools used in energy management. The use of best practices in wiring and grounding (earthing) ensures safety, prevents fire hazards and importantly allows a piece of equipment to function in its intended manner without significant loss of performance and life expectancy. It improves efficiency and quality […]
Electromagnetic Compatibility (EMC) – The Fundamentals
In certain environments, electromagnetic energy is unintentionally generated, propagated and the reception cause major HSE challenges like noise, discomfort, pollution, affecting performance and physical damage of equipment or systems, injury and even loss of life. Electromagnetic compatibility is concerned with efficient operation and performance of equipment in an electromagnetic environment. The international Electrotechnical Committee (IEC) […]
Power Factor (PF)
Power factor is a critical issue in commercial and industrial establishments. The proper management of power factor for organisations, saves money, enhances operations, extends life expectancy of machinery and saves utility penalties. From the electricity utility perspective it frees up energy for other customers and reduces pressure on electrical infrastructure. It is therefore a power […]
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 […]
