What is service mains in power transmission system?
A 'service mains' is not associated with an electricity 'transmission' system, but with a low-voltage 'distribution' system. The service mains is the name given to the cable that connects a building to the low-voltage mains supply.
How could you test the circuit before you power it up?
There are many ways of testing many types of circuits. The procedure depends on the circuit. It is important though not to play with electricity unless you know what you are doing yourself properly. If you don't know, take the circuit to someone who does. DO NOT PLAY AROUND WITH ELECTRICITY WITHOUT SUPERVISION. DO NOT PLAY WITH MAINS OPERATED EQUIPMENT UNTIL YOU HAVE AT LEAST COMPLETED A COURSE. DO NOT USE WATER BASED FIRE EXTINGUISHERS ON ELECTRICAL FIRES. NOBODY AT WIKIANSWERS WANTS TO SEE YOU HURT.
How does AMF panel for generator work?
AMF stand for Auto Mains Failure. Generally a generator/alternator power and normal commercial line switching over is done through it. A normal changeover, if mains fails you have switch the load circuit to generator, and when mains restors, generator supply will be cut off and fed to mains. in AMF this done by contactors and control circuits. if you want to know more......
Advantage electrical rising mains?
Rising mains come up from underground so they are less likely to be affected by weather conditions and they are not an eyesore.
Is the frequency of the UK mains supply suitable?
no
Which rectifier is not directly operated from mains?
Because , the high voltage can destroy the diodes used in the rectifier .
What is the frequency of ac voltage?
-- 60 Hz mains in North America, Latin America, a few other places -- 50 Hz mains in Europe, Asia, most other places -- Anything at all, from DC to daylight, depending on the application, in non-mains circuits
Does a dishwasher use battery or mains?
I have installed hundreds of dishwashers and never seen a battery operated oneI have installed hundreds of dishwashers and never seen a battery operated one
Advantage of current limiting?
Current limiting is the practice in electrical or electronic circuits of imposing an upper limit on the current. The simplest form of current limiting in mains is fuse.
How do you wire three phase into the mains?
In the UK, the term, 'mains', refers to the supply voltage provided by the distribution system. In most residential properties, the mains' supply is single phase (there are exceptions: some European countries have three-phase supplies), in which case you cannot 'wire' a three-phase load such as an induction motor into the mains.
Where is the PS vita charger?
The Vita's charger comes in the box. It is in two parts - one with a mains plug and adaptor, the other has a USB plug and one to fit into the Vita. You can use the latter to charge directly from a PC, or both together to charge from the mains.
What are some of the most recommended smoke alarms that operated off the mains electricity?
Some of the most recommended mains powered smoke alarms include BRK, Firex, First Alert, and Kidde. These brands can be purchased at most home improvement stores and online at retailers including Lowes, Home Depot, and Global Industries.
Is a battery considered electricity?
The battery is not electricity. A battery is a device that stores energy in the form of chemical energy. When energy is taken out of the battery, it comes out in the form of electrical energy. And if the battery is rechargable, then energy is put into it also in the form of electrical energy. A2. There is sometimes a confusion, amongst non-technical people when discussing electrical items. A distinction is made between an AC mains operated device and a battery operated device. Calling the mains device 'electric' and the other 'battery'. A battery operated device is also 'electric', The current is DC and the voltage usually a lot lower (and safer) than the domestic supply. So yes. A battery operated device is electric. Batteries do produce electricity.
How does the electric distribution panel work?
It's basically a system of circuits. The power from the mains enters through the input terminals. It's then split into various load circuits (5 amp for lighting, 13 amp for sockets , 15 amp for the immersion heater & 30 amp for cookers). Each of these circuits has it's own circuit breaker, which cuts the power to that particular circuit if the current draw exceeds the rating of the breaker.
What are the hazards associated with assembling and testing electronic circuits and how they can be minimised?
Hazards associated with assembling and testing electronic circuits include slashed chemicals, and toxic fumes. These hazards can be minimized by proper ventilation, and wearing protective gear.
Can you have multiple main method in the same class?
according to my knowledge it is no a main can have multiple classes but a class cannot have multiple mains...main indicates the beginning of a program and if we have n number of mains then the compiler will show an error in all the main program that we write
