  On January 5, 2021, a recognized domestic expert in the field of grounding and lightning protection, Shahzad Muhammad Khan is the TechnicalDirector will hold a webinar on the topic "Grounding and lightning protection. Methods of active influence on lightning. How effective and expedient are active lightning rods". This is the sixth webinar in the series "Grounding and Lightning Protection - Issues and Problems Arising in Design".

  DESCRIPTION OF THE EVENT

  Is it possible to control the lightning strike point? To this question, any specialist, without hesitation, will give a positive answer. He will think when the question is clarified ''…for the purposes of practical Lightning Protection.'' Click here

  Now we have to take into account the cost of generating control actions, their reliability, operating costs, and compatibility with the technological functions of the protected object.

  The physics of control actions on lightning is clear. The lightning strike point is determined by the channel of the counter leader, which starts from the ground structure. To achieve effective protection against direct lightning strikes, it is necessary either to initiate the counter leader from the lightning rod as early as possible or to slow it down from the protected object. The required levels of control actions are also known. Unfortunately, they are realizable for research purposes but are not very suitable for mass practical lightning protection. That is why neither in Pakistan nor in the vast majority of technically developed countries, regulatory documents on lightning protection are guided by active lightning rods.

  However, advertising of active lightning rods is carried out by all permitted and prohibited methods. Unfortunately, even the decision-making bodies of our country are involved in the advertising process. In this form, a commercial event becomes socially dangerous and needs to be resisted. This webinar is planned to give a detailed analysis of the mechanisms of control actions on lightning, to provide factual data on their real capabilities obtained in the course of field observations, laboratory studies, and theoretical considerations. It is also supposed to consider the consequences of the possible use of active lightning rods (including the most famous ESE Lightning Rods) at real industrial facilities.

  In conclusion, the possibilities of combining active lightning rods with the domestic regulatory framework for lightning protection will be considered and the prospects for the planned developments will be assessed.

  Posted in the topic LED ecological lighting: light that cares for the environment in the forum Technology

  March 1, 2022 5:48 AM EST

  LED technology has given rise to a type of ecological lighting that helps take care of the environment. The entire LED Light Bulbs is much more efficient than the conventional one, even than the low consumption one, basically because of the materials that it is made of and because of the way it produces light.

  LED lighting is made up of diodes, which are semiconductor elements that emit light when electricity flows through them. It does not require filaments or gas to work and also does not transform light into heat.

  This technology has the lowest energy consumption produced to date. Plus, LED Light Bulbs last up to 20 times longer than incandescent bulbs! Their maintenance costs are very low, they have a long useful life and they reduce light pollution.

  As if that were not enough, another of its benefits is that they are made with recyclable materials and does not contain polluting elements such as mercury.

  In fact, with the progressive withdrawal of halogen lighting products from the market by the European Union, as it did previously with filament bulbs, confidence in LED is shown to be the lighting technology of the future that we can start enjoying today.

  Let's see in more detail what the advantages that LED ecological lighting offer us are and how we can contribute our grain of sand in this fight for the care of the environment.

  10 advantages of LED ecological lighting for the environment

  1. LED lighting is energy efficient.

  An incandescent light bulb loses 80% of its energy as heat, leaving only the last 20% for light emission. On the other hand, LED light bulbs work just the opposite, they allocate a scant 20% of their energy to heat generation. With all this, even compared to so-called low consumption light bulbs, we achieve energy savings that are in the range of 50% to 80%.

  2. LED bulbs last longer.

  Without a filament to break or burn out, LED bulbs can last up to 20 times longer than incandescent bulbs. Its useful life is around 50,000 hours compared to 2,000 for a standard LED Light Bulbs. So with this type of lighting, there is no need to replace the bulbs so frequently and as a consequence, no waste is generated, this ecological LED lighting being an economical and effective alternative.

  3. LEDs are more colorful.

  LED Bulbs can be manufactured in a wide range of colors without the use of additional filters, thus reducing production costs. They also provide a brighter color than a filtered bulb and emit light more similar to natural light, since with LED ecological lighting we enjoy a color rendering index greater than 80 out of 100 and, in addition, with minimal energy consumption.

  4. Eco-friendly LED lighting is quieter.

  The days of light bulbs making an annoying noise are over with the creation of LEDs, so there's no need to lose your sanity listening to transformers hum or other light bulbs rattle.

  5. LED bulbs are safe.

  Because they consume so little power, LED light bulbs don't overheat. They are always kept cold, which reduces the risk of causing burns both in the support where they are placed and in people. In addition, the LED lamps are very stable and resistant to vibration and shock. This avoids, on the one hand, the risks of accidents due to accidental breakage and therefore reduces the production of residual waste.

  6. The light from the LED light bulbs is in focus.

  LED luminaires can be centered without the use of additional reflectors or lenses, which means less fixture production volume and lower cost for the same light beam.

  7. LED is the best option to regulate light intensity.

  Incandescent bulbs turn yellow when dimmed, while LED bulbs retain their true colors. The LED lights adapt to the lighting needs of the environment, facilitating the regulation of both the tone and the intensity of the light.

  8. LEDs are flexible.

  Thanks to their wide range of colors and shapes, LEDs can replace any conventional light bulb. Its tiny size and low power consumption also open up a world of possibilities, from infrared remote control lights to ultra-light headlights.

  9. LED light bulbs to turn on immediately.

  Illuminating to full brightness in microseconds, LEDs are a safer option when reaction time is a factor, such as when the car in the fast lane slams on the brake pedal.

  10. They promise a brighter future.

  LED bulbs are a type of ecological lighting and therefore the lighting of the future. Unlike fluorescent bulbs, they do not contain mercury, making your recycling process easier and more environmentally friendly. In addition, the low consumption of LED luminaires is reflected in savings in CO2 and sulfur emissions, which benefit the environment and help protect our ecosystem.

  Efficiency isn't associated with load in that manner and does now no longer parent in what number of watts you want in your machine see edit on the bottom, I misinterpret your question.

  Getting a Power Supply Unit with extra watts than you want is to get longer existence from the PSU.

  When you push a PSU hard (i.e. power it close to its most output) it's going to burn out quicker.

  Burn out the capacitors derate over time, with use, and with heat. This makes them much less capacitive, lowering the strength of the PSU.

  A precise nice PSU while new might be capable of delivering a piece extra contemporary than its rating. But with use, someday later its max strength output will drop underneath its rated max.

  If you haven`t left any headroom and want nearly all that strength, that PSU isn't always going to close very lots longer. i.e. the closer its max output it's miles driven to, the quicker it's going to put on out. As its max output drops, the desired strength does not so it always receives driven tougher and tougher.

  Also, you may improve to extra effective hardware inside the destiny which in any other case wishes a PSU could change.

   I continually purchase a PSU with at least 1/three more strength headroom. If I want 550W I'll purchase a 750W.

  This proved practical closing 12 months after I sold a 3090 gfx card and happily already had sufficient strength to power it without changing the Meanwell Power Suppliesregardless of it already being nine yrs.’ old.

  Efficiency best influences how lots of strength is drawn from the wall socket for the quantity of strength your PC is using.

  The extra green its miles the much less more strength is pulled from the wall via way of means of the PSU for its inner operation. And additionally commonly reduces how warm the PSU receives.

  Efficiency will range from low watts to excessive watts, peaking someplace inside the middle. It does not typically range that lots except you operate little or no strength or close to max strength.

  This has not had anything to do with how lots strength your PC wishes, the PSU strength provided to the PC is unbiased of its performance.

  The best time performance which could assist with a strong draw problem (apart from the price of strength) is in case your PC is so effective, its PSU is maxing out a wall socket's contemporary capability.

  Then an extra green PSU can probably maintain you in the wall delivery constraint.

  Although undergo in mind, performance will lessen a bit the warmer the PSU receives and additionally with age/use.

  It can pay to maintain your PSU cool to apply a bit less strength and close longer.

  I reread your question, top performance does not range that lots over the strength variety to count except you push the PSU hard.

  Also, in case you insist on staying in the top performance zone, you may want to maintain your PC jogging hard, eating extra power anyway, and defeating the objective.

  If you're involved in approximate performance, get an exceptionally green PSU with a piece of strength headroom defined above, and contact it a day, you are not doing better.

  The Main Switch is only that. The "Crest Pak" switch switches the power off to the entire electrical establishment. The rating of the Main Switch alludes to how much current it can switch. It regularly doesn't have any over-burden insurance capacities. The Supply Authority will have their breakers between the buyer's mains (the wires coming into your place) and the Main Switch as security against devastating over-burden.

  After the Main Switch, power is disseminated to the different circuits (lights, power, cooling, high temp water, and so on) which are each secured by wires, or all the more regularly these days by circuit breakers or joined electrical switch/RCDs (remaining ebb and flow gadgets or "wellbeing switches").

  The circuit breakers can be switched off to segregate a circuit and will likewise consequently disengage the circuit assuming an over-burden or short out happens. They are evaluated to suit the normal circuit burden and size of the link utilized. On the off chance that the evaluated current is surpassed, then, at that point, the electrical switch will "trip". This isn't exceptional in winter when an individual’s plugin such a large number of radiators to one circuit and consequently over-burden it.

   RCD is a further degree of assurance that is needed for power and lighting in new establishments and suggested as a retrofit for old establishments. The RCD faculties any little current unevenness between the circuit dynamic and nonpartisan. This demonstrates that the current is streaming to earth someplace (perhaps through you!!!) and disengages the stock to the circuit before any harm is done or electric shock injury happens. They are not typically associated with circuits, for example, ovens or heated water, where there can be a few innate spillage momenta in components that may cause bogus "stumbling".

  Nowadays, one of the issues to know about with Main Switches is that they just separate the "mains supply". They don't detach the stock from a "Sun oriented Generator" which additionally must be disengaged independently.
