Harmonics – An overview
Harmonics are by-products of modern electronics and automation. They are especially prevalent where there are large number of personal computers, adjustable speed drives and other types of equipment that draw currents in a non-linear manner (short pulses). The consequences of harmonic distortion in our commercial and industrial establishments are not necessarily evil, but an issue […]
Lightning Protection (Structural) – Key Design Considerations
Lightning is one of nature’s most powerful and destructive phenomena, yet it is the most under rated weather hazard. With awesome amount of electrical energy (measured upto over 200,000 Amperes), wrecking tremendous havoc to life and infrastructure on its trail across all sectors, despite its brief duration of fractions of a second. The consequences of […]
400-mile-long Lightning bolt over Brazil is biggest in recorded history
On Halloween in 2018, the sky tore open above Brazil. A single gargantuan lightning bolt sliced through the atmosphere over the country’s southern tip, stretching more than 440 miles (700 kilometers) from the Atlantic coast into the edge of Argentina. According to a new analysis from the World Meteorological Organization (WMO), this epic “megaflash” was the single longest […]
How To Protect Your Solar Photovoltaic (PV) Systems
The PV systems are gaining popularity in the Renewable Energy sector. Despite the upsurge of the systems and its numerous benefits, they are exposed to the risk of Lightning strikes. PV systems are vulnerable to Electrical Surges or Transient overvoltages, that may enter the system following a direct Lightning strike to a structural LPS or […]
LIGHTNING 101 – 12 Key Facts
1. On average, Lightning strikes the earth 100 times every second, and Nigeria and the West Africa region has one of the highest number of thunderstorm days per annum in the world (180 days/year). An index of Lightning Flash Density. 2. Lightning causes Transient Overvoltages (very fast electrical ‘Surges’) on Power, Data Communication, Signal and […]
How To Effectively Protect Electronic Systems In A Mobile Base-Station From Damage Caused By Lightning And Surges (Transient Overvoltages)
Surges are large, very brief and potentially destructive due to sudden increase in voltage. They are the secondary effects of Lightning strikes from a kilo-metre or more, away. Structural Lightning Protection alone will NOT prevent Surges damage. Effective Protection for the Sensitive Electronic Equipment contained in a cell site can be achieved by fitting Surge […]
Plane is struck by lightning as more than 7000 bolts hit Sydney in one hour – with huge hailstones, heavy rainfall and devastating winds lashing the east coast
Severe storms have again lashed Australia’s east coast, with Sydney, the Hunter Valley and the NSW mid-north coast in the firing line. Large hailstones, heavy rainfall and damaging winds were forecast for the state’s north coast and west to Walgett, the Bureau of Meteorology warned. At least one plane was grounded after it was reportedly […]
Dubai’s Burj Khalifa gets struck by lightning
Amidst the heavy rains and lightning that lashed Dubai on Friday evening, Sheikh Hamdan bin Mohammed bin Rashid Al Maktoum, Crown Prince of Dubai, captured the incredible moment when a bolt of lightning struck the top of the world’s tallest building – Dubai’s Burj Khalifa. KT readers also captured the stunning moment from a different angle. […]
Energy Audit (Assessment) – Why It Should Be Tops for 2020
Energy Audit or Assessment is the foundation of Energy Management which is the use of Engineering Principles and Economic methods to optimize energy use in commercial and industrial facilities. It enhances Productivity, Efficiency, Profitability of operations and should be tops for businesses that want to be competitive in 2020. A proper energy audit or assessment […]
Surge Protection – Indemnify Your Critical Assets Today
The fact that Surges or transient overvoltages ravage Electronic components and systems that drive virtually all businesses today is obvious and real. From Manufacturing, Health delivery, Telecoms, ICT, Oil & Gas, Petrochemicals, Banking & Financial Institutions, Utilities/Energy and all industry sectors are dependent on modern Electronic systems which are all vulnerable. These affect components and […]
