Q: For eg in electricity board energy bills?: We refer to it as Demand Factor. Its the total calculations of all lighting, dedicated appliance, general use power in the unit of Current (Amps). We have a NEC formula to calculate what is required when build a dwelling or commercial build. usally done by engineers on the E-sheet of blue prints, but any lic. electrical contractor, journeyman, etc. can make those calculations. I am not going to write a 10 page explanation of Demand Factor calculations. Its not one easy formula. You have to add percentage value for light loads, general use is 180 watts per outlet. Continus duty circuits need to be cal. at 125% demandetc. See there is alot more, When I was an apprenntice I did not learn this stuff until fourth year. EDIT: Well isn't that a *****! Thats why i never heard of that term. UK refers to metered service as maximum demand? USA its called Kilowatt hour usage

Q: I need definitions of ship EquipmentMain switchboard:Distribution bus bars:Ship service generators:Main Engines:Prime mover:propulsion generators:propulsion motors:: relies upon on the country. worldwide waters: specific they are able to, regardless. maximum first-worldwide international locations require licensing of a few style, yet 0.33 worldwide international locations in many circumstances do not.

Q: i need what to do in a bad thunderstorm: definite. The turbulence interior a thunderstorm could nicely be very severe. in certainty, as a thunder cloud (cumulonimbus (cb)) is turning out to be, the air interior is being pushed up and large velocity and carried with it water particules. To fly with the aid of a cb is risky for the reason which you will positively stumble upon severe icing situations. Icing could reason subjects with the engines, besides as with the raise produced via and the soundness of the plane. it could additionally block static and pitot vents (required for various contraptions interior the airplane) whilst a thunderstorm is energetic, the water is in certainty too heavy and starts falling down interior the path of the cloud as hail or rain, yet this additionally reasons downdrafts (severe velocity wind transferring downwards) alongside with the updrafts this creates severe turbulence and in very great thunderstorms the rigidity from the downdrafts must be sufficient to rigidity an plane downwards in the direction of terrain. At airfields, physique of techniques and landings are no longer oftentimes allowed whilst an energetic thunderstorm is interior of sight because of this and likewise the prospect of windshear. With regards lightening - it is not the main deadly part of a thunderstorm in any respect. There are static wicks to disperse the electrical powered energy. in spite of the undeniable fact that, a marvelous flash can quickly degrade a pilots ingenious and prescient which isn't so risk-free. we've climate radar and could see the place they're and stay clear of them yet around the equator, multicell thunderstorms can selection for 100s of miles wherein case the very turbulent centres could be prevented yet patches which teach as lighter factors (amber on the climate radar) ought to nonetheless be flown with the aid of.

Q: How come water shorts things out when water doesn't even conduct electricity it is the minerals in the water. If you dropped pure water in electrical equipment what would happen: nothing would happen if you dropped pure water in electrical equipment and the electrical equipment is also pure without any dirt which is soluble in water. however, in real life, this is not possible. firstly, water which you get from your tap contains all sorts of impurities that dissociate into their ions when in aqueous form. hence, there is presence of free ions that can act as charge carriers to conduct electricity in tap water. if you are able to get pure water, without any impurities, it would be almost impossible to ensure that your electrical equipment is clean without any dirt and impurities on it which are soluble in water. Hence, these residue can dissolve and dissociate in water to form free ions that conduct electricity.

Q: I want to know how good of a shot I have if my MOS is for electrical power production or electrician, that I can receive the first duty station on my wishlist.Yes Im aware that the needs of the service come first.: Army MOS 21P (Prime Power Production) is in high demand. Depends on what your duty station of choice is 90% of those with the 21P MOS are assigned between 4 different posts.

Q: If the sprinklers go off and hit electrical equipment like computers would an electrical fire start and would the water still coming out the sprinklers only make this fire worse.: It wouldn't be good, let's put it that way. So if your thinking about doing this as a senior prankI wouldn't do it. Otherwise something very bad will happen.

Q: Actually in position, we have provided shade for an electrical equipment but sun is hitting during morning and evening. Can it be called as a shaded area?: Outside ambient temperatures are always measured in the shade away from direct sunlight. If your equipment is seeing direct sunlight in normally convective air, then you should use an infared remote sensing thermometer to measure different points on the outside and the inside of the equipment (if possible) to determine the ambient temperature (when exposed to direct sunlight). Alternately, you could place a thermistor, thermocouple, RTD, or semiconductor temperature sensor inside the equipment (always in the shade) and run wire leads outside the equipment container, then measure ambient temperature inside the equipment with a meter on the outside. .

Q: If a 3 phase motor is driving a load say a gear box, compressor, or fan (Non Electrical piece of equipment) Does the load in this case gear box, compressor, or fan required a safety ground? The motor has its own safety ground: If there is no electrical connections to them then grounding is optional.

Q: I just arrived at my cousin's house. He makes his own lamps and things. He uses batteries and circuits and lightbulbs, basically, living in a battery-lit home. Being ridiculously green, he claims its more energy efficient than using the city grid. We got in an argument about global warming, and in short he claimed he was helping by using battery power rather than electrical power. I said that wasn't accurate because batteries, lightbulbs, etc use more power than the grid does because they have to be made using electrical equipment in an electric factory. Am I right? What uses more power?: This debate depends on a few things such as how are the batteries charged, the cost of building the ciruits that operate the devices, the cost of electricity and other factors which I cannot think of right now. Also, are the batteries rechargeable? I would assume so in this case. I suspect that it would take a indeterminate period of time (at this point) for there to be a payoff for a battery run home to be less expensive that a conventionally powered home. Part of a conventionally powered home possibly being cheaper in the beginning would be the mass production of devices. When your cousin says things are powered by batteries, is it a battery bank supplying a converter of DC to AC or are his devices running soley on DC supplies? The best way to resolve the answer is to calculate all the electrical costs that go into powering his home and then also calculate how much it would be to run a similar home on the grid. There might also be a few costs that are left out due to their choices of what to leave out of their home or how they accomplish or forego the luxury of in their home. At this point, there are probably not enough studies available to get a general consenus of which is cheaper. There is also another point to consider which is how often do they have to replace their batteries?

Q: I measured it with a CRO in the physics lab and I was wondering what could be its source: That is a period of about 62 hours or 2.5 days! Are you sure you measured this with an oscilloscope, or does CRO mean something else to you? Maybe the motion of the planets, earth, moon, etc. I don't know? Do you mean a period of 4.5 microseconds? That would be 222kHz perhaps EMI from a computer, other electronic gear, short wave radio, etc. If you can clarify, I might be of more help. Edit: OK; I have a couple of ideas, but it can be DIFFICULT to find. I spent a long time trying to track down the source of 70MHz in my lab. Turns out there is a TV station (channel 4) transmitting about 1 mile away. Channel 4 occupies the space between 67.31MHz and 71.75MHz. 222 KHz has a wavelength of about 1350 meters. It takes a pretty big antenna to launch that as a traveling wave so I'm going guess its a near field source. A good way to look for it is to make a small loop antenna with a few turns of magnet wire (maybe a few 10s of cm in diameter) and hook it to your oscilloscope. Walk around with it putting it near any and all electrical equipment that is in or near your lab. Make sure to change the orientation of the coil when you are moving around. You are basically playing a game of hot and cold. Try to maximize the signal and in theory you should be near the source. Also, be suspicious of the lights. I know their source is 60Hz, but some electronic ballasts for fluorescents run at a pretty high frequency, at least 10's of KHz, you could be seeing a harmonic. Just try flipping the lights on and off looking for a change in amplitude of the signal on the scope. If this doesn't find it, then perhps it is far field? I don't know of any commercial braoadcasts at this frequency though. The low end of AM radio is around 500KHz. Maybe you have an active Ham radio operator in the neighborhood? I wouldn't think he would be transmitting all of the time though is this 'noise' always present? Hope this helps. Let me know if you find it. Dave
