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:For a year my wireless network has always been right at 56.0 Mbps. The last three days however, it has been all over the place (56, 0, 11, 18, 34, etc.) I am trying to figure out what could be causing my slow connection speed. It is a password protected network and I have changed the ip from the standard address.
It could be interference from other electrical equipment, or if there are other wireless networks around you, they could be operating on the same channel. Try shutting off any new electronics you may have gotten or try changing the channel that your router broadcasts in.
Q:I am studying in college to become an electrical engineer but there is one problem, i'm almost clueless about what i'll do once i graduate. like at what kind of companies and places will i work at? what will i be doing? whats it like to be an engineer? what will be my dutys?. and also how much does an engineer (more specifically the kind in my field) earn? really need to know this. thanks

Q:e.g. medical equipment
Best thing to do is use a surge protector and if the equipment is costly enough use one voltage stabiliser/CVT/UPS in addition.
Q:I just heard tapping noises coming from the back door. The back door leads to the laundry room and multiple storage rooms. There is also all the heating and electrical equipment down there. The leak is coming from a pipe at the ceiling in a storage one, the room beside all the electrical equipment. The floor is soaked and the water is leaking a lot. Am I in danger?
Are you in danger only if the water comes in contact with electrical wires yes have the pipe repaired call a plumber don't wait til Monday when it will be cheaper because it won't when the ceiling collapses some one may get hit with plaster board and the. You wind up with an even bigger hole . The longer you wait the more it will cost. Especially if a fire were to start remember water and electricity don't play well together some one can be electricuted
Q:I have a piece of electrical equipment that uses a 12v DC in that i want to replace with a battery, as it currently uses a wall charger with an AC converter. How would i go about doing this for cheap? making it myself wouldn't be out of the question, all i need is a guide. The 12v pack must also be as small as possible, as it is powering a portable device.
It relies upon what form of battery it is. Lead acid batteries (vehicle batteries) are extremely indestructible, yet nonetheless incorrect charging could nicely be risky by way of fact it may launch hydrogen gas it extremely is a fireplace of explosion possibility in restricted area. Over charging at a extreme fee could additionally overheat the battery and bodily harm it. best is a appropriate battery charger. a inexpensive charger could fee no longer extra effective than a mains adaptor besides. For different varieties of rechargeable battery you easily decide for a appropriate battery charger, or you will harm the battery in a small form of expenditures (in the worst case, the 1st time you attempt to fee it). If the device is often used the place there's a mains poiwer furnish, why no longer basically use a DC adapter particularly of the battery? to respond to your particular questions a million) confident. 2) No. forget approximately with regard to the advice in yet another answer approximately restricting the present with a diode. in case you knew adequate to layout your person battery charger suitable, you probable does no longer be asking this question!
Q:After all, the whole point of ATEX certification is that it doesn't make a fire. One would think if you can safely use something in an explosive atmosphere you can use it on shabbos. By the same token a shabbos light should be safe to use in an explosive atmosphere.
When I was in fourth grade, the science teacher taught us the physics definition of work and explained how it differs from the everyday definition of work Much like that -- Jewish legal definitions of Hebrew words do not always line up perfectly with the everyday use of English words that aproximate them. With electrical items, the prohibition of fire is only one of the prohibitions to be aware of for Shabbat -- off the top of my head, there is also boneh (building) and bishul (cooking) On the reverse side -- your logic does not hold in even the most basic English definition. It is only the Karaites that believe there is a Shabbat prohibition of fire, the normative prohibition is on making fire and putting out fire -- thus, there are quite a few devices used on Shabbat that are straight forwardly on fire (well, heck -- just think of the candles themselves!!!) A Shabbat lamp is simply always on - but has some cover to keep the light from bothering. Hopefuly, this whole structure is well insulated (I don't know -- never used one)
Q:Before anyone blindly answers this, I'd like to first request that only people in the power transmission industry answer, as they are the only ones likely to know.I have a customer who is asking to mount several very large pieces of electrical equipment 15 feet in the air, mounted to a large structure. All of these equipment pieces are 5000 or more pounds and pad-mount by design. I am questioning this request on the basis of legality. Basically, I am curious to know, is there anything in the NEC that says mounting pad-mount equipment overhead is illegal? If so, I could really use a hint as to what section of the NEC code.
I don't believe that there is anything in the NEC that addresses this. Obviously, installing anything on a structure presents challenges that require the attention of a qualified structural engineer. And depending on the location, you could be facing some additional concerns. You would need to check on seismic activity in the area, and since 'pad mount' equipment has a broad profile, wind-loading could be more challenging if you have a wind-force specification to meet. The other issue you would need to consider is whether installation on a structure presents any particular safety concerns. Without knowing any more, my inclination would be to think that you might want to provide an enclosure around the structure to prevent civilians (rmeaning 'teenagers and drunk college students) from climbing it. Just out of curiosity - why does your client want this? We know that the client is always right - even when he insists to stupid things. I trust there is a good reason for asking for something that is bound to increase installation cost by probably 100%.
Q:i want to where I can transformator ( i do not know the name)But I whant to there is some equipment the you connetectwith your device it will change the current. And please wherecan I buy and approximatly what is the price?Thank you
yes u can but u would need a power volt changer to make them work in the usa the power converters cost between 10.00 - 100.00 dollars
Q:I was thinking of making a video game collection, I allready have a big one but only containing systems and games with CDs. But no collection is complete without the retro NES or SNES or the old school consoles with cartridges. My question is where would be a good place to store them? Because god knows how difficult it is to find a complete set with the box and Manuel and everything so I'll have to deal with just buying the cartridge. If you could help out I greatly appreciate it!
you always wanna store any kind of electrical equipment in a cool dry place. when it comes to Nes stuff same thing, if you really wanna make sure they will be good to go use a tote container or plastic cooler. something with a sealable possibly water proof lids. i have all my nintendo stuff sitting in a red igloo cooler in my storage unit. it has been there for over three years now and nothing wrong. just make sure you use a qtip and some alcohol to clean the pins up nice before placing in any system. you dont wan any dust that might have collected to go inside your machines.
