- Q:hi guyscan you explain in simple words what is earthing process and how it helps to secure human from detected current.thanks
- Earthing system helping for Human safety to avoid electrocution due to earth leakage.Earth is acting like a Huge conductor because of it minerals Moisture contend (water).If any electrical equipment Insulation failure leakage will be there ,if the same equipment is not Grounded ,there is a possibilitiesof getting electric shock to Human.If the same equipment is Grounded the leakage current will flow to Earth protect from electric shocks Trip the circuit. Pl. check this link for brief idea.
- Q:I have heard, (I can't recall where), that the Earth's natural magnetic field is slowly declining. I have also heard that solar flares can disrupt the operation of electrical/electronic equipment. Would either of these natural phenomena affect the operation of electronic/electrical equipment? Please answer each query briefly, and provide links if possible.
- Electrical/Electronic equipment is only effected by something called Electro Magnetic Interference (EMI). The Earth Magnetic field usually does not create this kind of interference. The solar flares on the other hand can produce EMI. However, there are ways you can protect your electrical equipment from the EMI by shielding the equipment from the source of EMI. The thickness of the shield depends on the frequency of the EMI and the conductivity of the metal that is using as the shield. In general, a good conductor metal is the good shield such as Nickel, Silver, Copper, etc. Another way to protect a electrical component against the EMI is using a high permeability metal (hi-mu metal).
- Q:Fires are classified by the fuel involved. Name the type of fire extinguisher which must be used in the event of the each of the following fires 1. Cooking oils 2. Flammable liquids 3. Electrical equipment Thanks.
- For cooking oils, greases and paints or Flammable liquidstype B while electrical equipment its type C fire extinguisher.
- Q:I am a commercial real estate appraiser and I oftentimes need to be specific about the electrical service available within a building. I can read the service panel(s) and total the various amps volts, but I don't know what is relevant to report. For example, I recently inspected a very large industrial building and all of the service panels combined had a total of 30,000 amp, and I also noted that it had a 3-phase unit. Is that relevant to report that is was 30,000 amp, 3-phase service? Should I also report the voltage? Should it read: 30,000 amp/### volt 3-phase service. In the future, can I just read the service panel(s) and total the numbers? Just because a panel says 4000 amps, does that mean it actually has 4000, or that it can handle that many amps?I know that's allot of questions, but any help that I can get would be helpful. Thanks!
- You would be better off to hire an electrician to get this info as there are a lot of variables. The voltages and phases available, the amps available, and the number of circuits in each one. Many panels you have to remove the cover to see the rating, and this is dangerous. A typical building may have thirty 225 amp 3 ph. lighting panels that are fed off of 60 amp circuits for 277 vac lighting. The service may only be 800 amps for the whole building. This is very common and meets NEC requirements. The largest bldg. where I work at the Univ. is 400k sq ft and has a 4000 amp service at the 480 volt level. This is the same as 145 amps at the 13.2 kv level. It all depends on whether or not you own the high voltage service also. An industrial bldg. could be much more.
- Q:I need to cut a hole through 2(ish)cm of metal, or some sort of composite material I have at home to feed a few wires through. Is it possible to do it without any electrical equipment?
- If you dont mind hammering with a pretty sharp pick for about an hour. Drill with a metal drill bit or a plasma welder would probably save you alot of time. YOu can rent those
- Q:I need definitions of ship EquipmentMain switchboard:Distribution bus bars:Ship service generators:Main Engines:Prime mover:propulsion generators:propulsion motors:
- It is assumed that this enquiry is in respect of large cargo or passenger vessels, not little pleasure boats. Main switchboard. This is the electrical switch panel to which all of the supplies from the service generators are led and from which all supplies to engineroom electrical equipment, deck machinery and the ships general electrical equipment, galley, navigation equipment, lighting, ventilation etc are supplied. The main switchboard comprises distribution bus bars, switches, meters and on AC ships, now in the the majority, the equipment required to synchronise the phases of the service generators. The distribution bus bars are the principal electrical conductors to which the generator outputs can be switched and from which the circuits to the rest of the ships electrical equipment are supplied. There are usually four bus bars, three carrying electricity at 415 or 440 volts three phase and a neutral bar. The current is usually supplied with a frequency of 50 Herz or 60 Herz. Ships service generators are in modern ships alternator units which supply all electrical requirements with the exception of the ship's propulsion. They are normally powered by diesel engines or steam turbines and in some naval vessels by gas turbines. Main engines. This term is invariably used for the vessel's propulsion machinery. Prime mover. This is a general term not restricted to marine practice for any machine the converts the energy of a fuel or the heat energy of steam into kinetic energy. Propulsion generators. These can be DC generators or AC alternators which have outputs dedicated for ship's propulsion purposes. The are usually connected independently of the main switchboard via a dedicated propulsion switchboard. Propulsion motors. These are electric motors which drive the ship's propellers. They are usually inboard but many modern cruise ships have their propulsion motors within pods which are outside of the main hull.
- Q:I am interested in buying a house and the village water supply enters the house right next to the electrical panel in the basement. I am concerned that this might be a code violation and not pass inspection. Any thoughts?
- According to code you should be six ft. away from any sort of water line for a fuse box, or panel.
- Q:I suspect my house electrical ground isn't working and had suffered equipment loss due to loss thunder strike.
- If the Lightning is hitting your house then you need to call in a profesional for insurance reasons. If it is hitting elsewhere and causing damage through you electrical lines or through your grounding system then you need to look into surge suppresion for your system.
- Q:I just moved into a house a week ago and for the past couple of days weird things have been happening. The night before last my tv in my bedroom changed channel by itself and also I had a playstation remote sitting on top of my playstation and that fell on its own. Last night I was laying in bed and my door opened by itself and I am 100% sure that it was shut all the way. And again in the middle of the night it changed channel. I'm starting to get scared because all of this happens when my boyfriend is at work and its just me and my two boys. Is my house haunted, and what can I do?Btw my house is probably 100 years old.
- First off eliminate all rational explanation before jumping to supernatural possibilities. TV channels changing by themselves are usually caused by batteries going in your remote control, so change the batteries in your remote control to eliminate this possibility. If the batteries in your remote are brand new try changing channel through a brick wall - go into another room and see if you can change the channel - not all remote controls are infra red. If you can change channel through a brick wall chances are your neighbour has the same TV as you and his remote is changing your channel. If those possibilities have been eliminated you will need to take your TV to a repair shop to get it checked for faulty wiring. As for the playstation remote just falling off by itself, that is likely caused by what I call catastrophe theorem. You think something is stable on a surface because it doesn't look like it's moving but in reality it is moving just very very slowly. Over time it moves to a tipping point where more of the weight is over the edge than is holding it in place so it suddenly drops off. Often sudden inexplicable movements are the result of the cumulative effects of tiny imperceptible movements. As for the door opening by itself, you need to check that all the windows are closed and the house isn't drafty. If the doors are light weight and a window is open or the house is drafty a decent gust of wind can open doors and slam them shut. For your peace of mind you should check into all these things, and hopefully that will put your mind at rest and your children will stop being scared.
