Types of circuit breakers

The different types of high voltage circuit breakers which includes the following

Air Circuit Breaker
SF6 Circuit Breaker
Vacuum Circuit Breaker
Oil Circuit Breaker
Air Circuit Breaker

Air Circuit Breaker

This circuit breaker will operate in the air; the quenching medium is an Arc at atmospheric pressure. In many of the countries air circuit breaker is replaced by oil circuit breaker. About oil circuit breaker we will discuss later in the article. Thus the importance of ACB is still preferable choice to use an Air circuit breaker up to 15KV. This is because; oil circuit breaker may catch fire when used at 15V

SF6 Circuit Breaker

In the SF6 circuit breaker the current carrying contacts operate in sulphur hexafluoride gas is known as an SF6 circuit breaker. It is an excellent insulating property and high electro-negativity. It can be understood that, high affinity of absorbing free electron. The negative ion is formed when a free electron collides with the SF6 gas molecule; it is absorbed by that gas molecule.

Vacuum Circuit Breaker

A Vacuum circuit breaker is a circuit which vacuum is used to extinct the arc. It has dielectric recovery character, excellent interruption and can interrupt the high frequency current which results from arc instability, superimposed on the line frequency current.

Oil Circuit Breaker

In this type of circuit breaker oil is used, but mineral oil is preferable. It acts better insulating property than air. The moving contact and fixed contact are immerged inside the insulating oil. When the separation of current takes place, then carrier contacts in the oil, the arc in circuit breaker is initialized at the moment of separation of contacts, and because of this arc in the oil is vaporized and decomposed in hydrogen gas and finally creates a hydrogen bubble around the arc.

This highly compressed gas bubble around and arc prevents re-striking of the arc after current reaches zero crossing of the cycle. The OCB is the oldest type of circuit breakers.

Circuit Breakers

In the electrical and electronics world, there are many cases where mishap takes place. It will lead to severe damage to building, offices, houses, schools, industries, etc. Trusting voltage and current are not correct, though safety measures are taken. Once circuit breakers are installed it will control the sudden rise of voltage and current. It will help from any accident. Circuit breakers are like the heart of the electrical system. There are different types of circuit breakers where these are installed according to the rating of the system. In house different kind of circuit breaker is used and for industries another type of circuit breaker is used.

What is a Circuit Breaker?

Electrical circuit breaker is a witching device which can be operated automatically or manually for protecting and controlling of electrical power system. In the modern power system the design of the circuit breaker has changed depending upon the huge currents and to prevent from arc while operating.

Electricity which is coming to the houses or offices or schools or industries or to any other places from the power distribution grids forms a large circuit. Those lines which are connected to the power plant forming at one end is called the hot wire and the other lines connecting to ground forming other end. Whenever the electrical charge flows between these two lines it develops potential between them. For the complete circuit the connection of loads (appliances) offers resistance to the flow of charge and the whole electrical system inside the house or industries will work smoothly.

They work smoothly as long as the appliances have sufficiently resistant and do not cause any over current or voltage. The reasons for heating up the wires are too much charge flowing through the circuit or short circuiting or sudden connection of the hot end wire to the ground wire would heat up the wires, causing fire. The circuit breaker will prevent such situations which simply cut off the remaining circuit.

Easier Home Electric Wiring

Even if you’ve got years of wiring expertise, there are perpetually a number of tricks you will not understand. So, we have pulled together some tips, tricks and techniques for you.

Uncoil Cable while not Kinks

Pulling plastic-sheathed cable through holes within the framing could be a heap easier if you straighten the cable out 1st. If you merely pull the cable from the middle of the coil, it’s going to kink as you pull it through the studs. The trick is to raise some of coils from the middle of the roll (left) and toss them across the ground as if you are throwing a looped rope.

Pack Electrical Boxes showing neatness

If you have done abundant wiring, we’re certain you have had times once you may barely push the switch or outlet into the box as a result of there have been such a big amount of wires. the answer is to rearrange the wires showing neatness and so fold them fastidiously into the box.

Remove overlayer from Underground Feeder (UF) Cable

Underground feeder (UF) cable features a robust plastic overlayer that permits you to bury it directly within the ground while not running it through a passage (of course, it’s to be buried deep enough to satisfy the electrical code). however that robust overlayer is additionally troublesome to remove—unless you recognize this trick. begin by separating the black and white wires from the blank copper by grabbing every with pliers and twisting (top). they are simple to pan once you get them started. Pull them apart till you’ve got a couple of foot of separated wires. Next, take away the overlayer from the insulated wires by grabbing the top of the wire with one pliers and also the overlayer with another pliers and dealing them apart. once you get the overlayer separated from the insulated wire at the highest, simply peel it off (bottom). Repeat the method to get rid of the overlayer from the black wire. Finally, interrupt the loose overlayer with scissors or a knife.

No-Snag Fish Tape Connections

After planning to all the difficulty of operating your fish tape to its destination, the final thing you wish is to lose the cable or get your tape stuck on one thing within the wall as you pull it back.

Identify Roughed-In Wires

Save yourself lots of headaches by characteristic the wires as you put in them. it is a heap more durable to work out that wires go wherever once they are coated with drywall.

Test Wires Before Touching

When you have done lots of wiring, it is simple to urge content concerning whether or not the facility is off. But don’t. Use a noncontact voltage detector to ascertain each wire within the box or space during which you are operating. perpetually check the tester on a wire or twine you recognize is live to create certain it’s operating before you admit it.

Troubleshooting GFCIs

For starters, we have a tendency to found that almost all complaints occur once many retailers ar protected by one GFCI. There ar many doable causes, starting from a lightweight or appliance with a ground fault that is blocked into a downstream outlet, to a defective GFCI or maybe a circuit with an excessive amount of cable. to work out whether or not the matter is with the GFCI itself, or downstream, close up the facility to the GFCI and disconnect the wires from the “load” terminals. Push the push button (if it does not click, you will have to reset it once the facility is back on) and plug a GFCI tester into the GFCI outlet before you switch the facility back on. If the GFCI visits once you switch the facility on, replace it. If it holds, then the matter is with one in all the downstream retailers.

Multiple Switches, One Hot Wire

A box with 3 switches is huddled enough while not adding further wire connectors and pigtails. rather than running a separate plait from the new wire to every switch, simply leave the new wire further long. to attach the switches, merely score the wire along with your wire stripper and push the insulation to show concerning 3/4 in. of blank wire (left). Wrap this blank section a minimum of three-quarters of the manner round the screw terminal of the primary switch. Repeat the method for the remaining intermediate switches (right). Connect the last switch within the usual manner, process the wire round the screw in a very dextrorotary direction.

Strip Cable over layer 1st

It’s tempting to push your roughed-in cable through the knockouts within the box and worry concerning a way to strip the over layer later. however that is the arduous manner. It’s abundant easier to get rid of the over layer before you push the wires into the box.
