What can we possibly do to ensure a bright

A world with no computers, no smart phones, no gaming consoles, and no TVs. Because all these gadgets and devices need electricity for battery recharge. And the way we’re losing out on our natural resources, it’s not difficult to guess the number of years in which we would run out of all resources and without resources, we won’t be able to produce any electricity. What can we possibly do to ensure a bright future to our coming generations?Three things. One, we should adopt all possible energy saving practices which start with switching off your tube light,single phase meter shunt fan, and air conditioner when you’re not in the room. This simple step has the potential to brighten the very bleak future that’s hovering over all of us. Let’s promise ourselves that from this moment onwards, we’ll try conserving energy whether we’re at home or at home. The next time you leave for you, try switching off that fan running over your head. Second, we should develop a smart power infrastructure. And everyone in the power industry, including electricity companies to power distribution transformers manufacturers, has to play a role in this movement. Fuels must be transported, handled, and used with wisdom so wastage can be reduced and more electricity can be produced from less of fuels. For example, power distribution transfer manufacturers have to come out of their shell and develop some seriously incredible transformers that better handle electricity flow and distribute. Transformers play a great role in the entire power distribution infrastructure and therefore, more work needs to be done to make them smarter. Third step towards ensuring a bright future for the coming generations is to step into the green energy zone. Nature has gifted us abundance of clean energy in the form of air and sun rays, which can be stored and processed into energy and electricity. We’ve the ways to combat with the energy issues that will in all its likelihood impede our growth. The right approach therefore would be to start early with a plan. But one alone cannot do much – we all have to jump into it and face it head on. So whether it is the government, the common folks, the power companies, or the power distribution transformers manufacturers, we all have to do our bit to ensure a green, energy-secured planet. Last, let us remind ourselves for once and all that Mother Nature has enough for our needs, but not enough for our greed.

Nowadays, more and more monitor comes in with flyback transformers

Nowadays, more and more monitor comes in with flyback transformers

Nowadays, more and more monitor comes in with flyback transformers problems. Testing flyback transformers are not difficult if you carefully follow the instruction. In many cases, the flyback transformer can become short circuit after using not more than 2 years. This is partly due to bad design and low quality materials used during manufactures flyback transformer. The question is what kind of problems can be found in a flyback transformer and how to test and when to replace it. Here is an explanation that will help you to identify many flyback transformer problems.There are nine common problems can be found in a flyback transformer.a) A shorted turned in the primary winding. b) An open or shorted internal capacitor in secondary section.c) Flyback Transformer becomes bulged or cracked.d) External arcing to ground.e) Internal arcing between windings.f) Shorted internal high voltage diode ctpt groupwave in secondary winding.g) Breakdown in focus / screen voltage divider causing blur display. h) Flyback Transformer breakdown at full operating voltage (breakdown when under load).i) Short circuit between primary and secondary winding.Testing flyback transformer will be base on (a) and (b) since problem (c) is visible while problem (d) and (e) can be detected by hearing the arcing sound generated by the flyback transformer. Problem (f) can be checked with multimeter set to the highest range measured from anode to ABL pin while (g) can be solved by adding a new monitor blur buster (For 14' & 15' monitor only.) Problem (h) can only be tested by substituting a known good similar Flyback Transformer. Different monitor have different type of flyback transformer design. Problem (i) can be checked using an ohm meter measuring between primaryand secondary winding. A shorted turned or open in secondary winding is very uncommon.What type of symptoms will appear if there is a shorted turned in primary winding?a) No display (No high voltage).b) Power blink.c) B+ voltage drop.d) Horizontal output transistor will get very hot and later become shorted.e) Along B+ line components will spoilt. Example:- secondary diode UF5404 and B+ FET IRF630.f) Sometimes it will cause the power section to blow.What type of symptoms will appear if a capacitor is open or shorted in a flyback transformer?Capacitor shorted a. No display (No high voltage). b. B+ voltage drop. c. Secondary diode (UF5404) will burned or shorted. d. Horizontal output transistor will get shorted. e. Power blink. f. Sometimes power section will blow, for example: Raffles 15 inch monitor. g. Power section shut down for example: Compaq V55, Samtron 4bi monitor. h. Sometimes the automatic brightness limiter (ABL) circuitry components will get burned.This circuit is usually located beside the flyback transformer. For example: LG520si Capacitor open a. High voltage shut down.b. Monitor will have ‘tic - tic’ sound. Sometimes the capacitor may measure O.K. but break down when under full operating voltage. c. Horizontal output transistor will blow in a few hours or days after you have replaced it. d. Sometimes it will cause intermittent "no display". e. Distorted display i.e., the display will go in and out.f. It will cause horizontal output transistor to become shorted and blow the power section. How to check if a primary winding is good or bad in a Flyback Transformer?a) By using a flyback/LOPT tester, this instrument identifies faults in primary winding by doing a ‘ring’ test.b) It can test the winding even with only one shorted turned.c) This meter is handy and easy to use.d) Just simply connect the probe to primary winding.e) The readout is a clear ‘bar graph’ display which show you if the flyback transformer primary winding is good or shorted.f) The LOPT Tester also can be used to check the CRT YOKE coil, B+ coil and switch mode power transformer winding.NOTE: Measuring the resistance winding of a flyback transformer, yoke coil, B+ coil and SMPS winding using a multimeter can MISLEAD a technician into believing that a shorted winding is good. This can waste his precious time and time is money. How to diagnose if the internal capacitor is open or shorted?By using a normal analog multimeter and a digital capacitance meter. A good capacitor have the range from 1.5 nanofarad to 3 nanofarad.*1) First set your multimeter to X10K range.2) Place your probe to anode and cold ground.3) You must remove the anode cap in order to get a precise reading.4) Cold ground means the monitor chassis ground.5) If the needle of the multimeter shows a low ohms reading, this mean the internal capacitor is shorted.6) If the needle does not move at all, this doesn’t mean that the capacitor is O.K.7) You have to confirm this by using a digital capacitance meter which you can easily get one from local distributor.8) If the reading from the digital capacitance meter shows 2.7nf, this mean the capacitor is within range (O.K.).9) And if the reading showed 0.3nf, this mean the capacitor is open.10) You have three options if the capacitor is open or shorted.- Install a new flyback transformer or- Send the flyback transformer for refurbishing or - Send the monitor back to customers after spending many hours and much effort on it.However certain monitors may have the value of 4.5nf, 6nf and 7.2nf.Note: Sometimes the internal capacitor pin is connected to circuits (feedback) instead of ground.Tv rca flyback transformer circuits usually do not have a internal capacitor in it. If you have a flyback diagram and circuits which you can get it from the net, that would be an advantageto easily understand how to check them.

what Three-phase DC Immune Anti-Magnetic Current Transformer companies developed

what Three-phase DC Immune Anti-Magnetic Current Transformer companies developed

.then DSL, cable, & satellite access.. And company R&D is gearing up in unprecedented ways to prepare for that surprising leap in expectation. The companies drove what was available & came to market.we had dial-up internet. Those that do will be better positioned to capture what markets are created by consumer demand.. First... The companies drove the market & what was in it. Notice I said expectation. That aside, I'd really like to see what you think of this shift in product development and market control to consumer "vision" vice company "idea" driven. That's a drastic change in thinking that companies must now deal with... Second.. What do you think the future holds? DC Series Split Core Current with shielded three-phase

We had high cpm PSTN / POTS residential phone calls..including any technology "advancements" and their application, distribution, etc. Seems the old business model in Telco was that whatever the companies came up with is what the consumer would take...... But that is old world thinking.. We've seen. then flat rate LD.... And the foundation of this new consumer driven demand will likely be based on VoIP (and I believe wireless) technology.VoIP technology (note I didn't three phase meter current transformer say VoIP "phone") stands to afford unprecedented advancements and capabilities yet to be seen... We had bulky analog cell phones then digital/PCS, text messaging, and now sleek video cellular. The reason is 2 fold.vice the old approach of markets being created by what Three-phase DC Immune Anti-Magnetic Current Transformer companies developed and released.now consumers are dictating to companies "we want this now come up with it".the old business model was that whatever companies came up with consumers would accept.a host of Gee Whiz break throughs & possibilities focused heavily on multi-media & data (both residential & business). Now Broadband phone (VoIP). The potential is boggling.. Remember. Now WiFi & soon reliable WiMax deployment.then we had bundled local/LD.fueled by the possibilities surrounding VoIP and wireless.. No more.. VoIP technology is & can be much more than that.......or soon will...But that's just the obvious action on the surface..
