ELECTRICAL EQUIPMENTS

Electrical equipment is an appliance powered by electricity. This includes an enclosure, several electrical components, power switch etc. A machine which is the part of an electrical distribution system can be put under the category of electrical equipment. The components in this include switch board, distribution board, circuit breakers, energy meters, transformers etc

Let’s have a look at some significant electrical equipment. Electrical switch board is a major appliance. It directs electricity from one form to another. These switch boards contain large number of panels and each of it contains switches to redirect electricity. Actually the control of electricity to this switch board is carried out by electrical generators. As the power law defines the amount of power entering and leaving the switch must be equal. So generators make this stable. While going to the technical side of switch boards, it contains bus bars inside the case to isolate the switch board from the connections before it gets opened.

Distribution board is key electrical equipment. The main function of a distribution board is to divide the electric power feed into subsidiary circuits. It provides a safety breaker and fuse for each circuit in a common enclosure and hence the distribution board is sometimes called as power breaker.

An unavoidable part in electrical equipment section is circuit breakers. Basically it is an electric switch. It is designed to protect a device from over current or short circuit. It detects the fault if any and stops the flow of current to it. It incorporates manual as well as automatic control for switching operations. The latter control employs relays and operates only under fault conditions.

Its known to every one, transformer holds the top slot in the priority list. It’s a static piece of apparatus by means of which electric power from one circuit is transformed into electrical power of the same frequency in another circuit. It can raise and lower the voltage according to the need with the increase or decrease in current. The physical basis of a transformer is mutual induction and it works under the principle of Faraday’s laws of electromagnetic induction.

The above explained are some of the main electrical equipments which hold the key place in this section.
