GZS1 (KYN28A) type indoor metalclad removable switchgear (hereinafter referred to as Switchgear) is a complete set of distributiondevice for single bus bar and single bus bar section system of 3-10kV 3phase AC 50HZ.
It is mainly used for implementing the functions of control, protection and monitor in power plant, medium and small electric generator station, industry and mine institution distribution, power receiving and power delivery of second substation in the electric system, large-scale HV electromotor start, and etc. for control, protection and monitor.
- 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:
- 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: during line to ground fault, is there really a current that will flow in the ground, how will the grounding rod help if there is no connection back to the source? please explain how grounding aids tripping of C.B's
- In maximum mainscontinual distribution structures, the impartial is grounded at the substation transformer and usually at the get right of entry to element to human being premises. If a fault takes position which leads to a stay conductor entering touch with an uncovered conductive section of the package, any cutting-edge will bypass to floor and holiday a circuit breaker.
- Q: I have a hot tub connected to a fused disconnect. That is fed from a 30 Amp circuit breaker in my main panel. I was told that i needed to have it protected by a GFCI breaker. Would it satisfy the NEC if i just replaced the current 30 amp breaker with a 30 amp GFCI breaker and left the disconnect between that and the hot tub?
- Curley, as I remember, one of your videos showed you and the other stooges connecting water pipes to the electrical conduits and the natural gas pipes, and then running water through these. Well ok, you did pull all of the wy-yas out of your electrical conduit before attaching the water lines to them. But I really think you should leave the home repairs to more qualified people, don't you think?
- Q: I would like a serious answer from a professional who would know about these things from being part of the military or etc.When the air burst missile exploded, everything electrical stopped working. At the end of the movie, the girl asked if the phones are working and the guy replied Are you kidding, they'll never be phones again.Is that a true statement? Can anything electrical ever work again?? Or did he say that because the world at the time in their point of view looked unrepairable ?Also, if I was in a well constructed fallout shelter with all my stuff and I wanted to save Computers, TV etc. will it get affected from the outside air burst missile? (I know a lot of people are gonna yell why keep those when you can't use electricity again after a nuclear war 1, I just wanted to know, 2 I could use them in the shelter if I have Generator batteries for room lighting and everything else)
- You should be concerned about protecting yourself,not your toys.A well constructed shelter (fashionable in the 50's)would keep you out of the Blast(maybe)but would not save you from the Gamma rays.Everything would be contaminated for hundreds of generations.Nothing would grow,water would be undrinkable.When and if you emerge from your shelter,what and who would you find?Back to the Stone age.Have you seen the series on Discovery,Life after PeopleIt would be awful if you survived.
- Q: i would like to know more about the functions of this room. What is the role of this room in electrical distribution in a building? What i know,an electrical components need to get through this room such as for lighting+ac, power socket, and essential power.
- A riser room is where the electrical distribution equipment ( Switchgears and Panels) that supplies the electrical systems of the building is located. Electrical conduits that feed the various equipment, A/C units and sub panels and fire pumps originate here.
- Q: i got this in a hairdressing assinment and i need to no about it x
- safety features of equipment. electrical connexion. must be earthed so no fires can occur or minimise. equipment must be checked every 6 to 9 mths for any electrical fault. etc
- Q: I am an electronics engg and have four year of exp in marketing .please do let me know the procedure to start such business. i have heard that we need to pay big amount as security to take dealership of any product .please also if some one can tell me the percentage margin left in trading.Is it profitable?? i want to open this company in rajasthan udaipur.
- Check your local news on how the industry is doing. Compare the unemployment and so forth to know if there is enough cash flow going on. Sometimes opening a business [which is risky] can work if you aim at a certain group and you know your audience. Do the investigating.
- Q: do mechanical engineers also get involved with electronics?
- Engineering is usually a team sport. The mechanical engineer consults with the electrical engineer for the development of the product, then it gets reviewed for approval by the principal engineer.
- 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
