Distribution Transformer:                                     The transformer is used in the distribution of electrical energy. It is called Distribution Transformer. Its rating is 200 KVA and it is a step down type. In this transformer whether the load is loaded or not, it is functioning 24 hours a day. This means that iron lasts continuously throughout the day while copper is based on the load load. So much so that the load more loads of copper loses and loads less as copper Iron deficiency in such transformer should be lower than Copper Loss. In other words, the transformer's efficiency should be greater on the 50% load. Such transformer's voltage regulation should be good. Power Transformer:                                      The transformer that is used for the transmission of electrical energy is called a power transformer. The rating of this transformer is 200KVA. Power transformer can be used to step up or step down the voltage on both ends of the power l

Transformer can be classified as follows 1. According to the type of code ...... core type, shell type, and berry type 2. Based on the voltage. Step up and step down transformer 3.Based on phase. ......... one phase and three phase transformer 4.The basis of power. ......... Lighting Transformer and Power Transformer 5.Based on the type of cooling. ...... self-cooled, air pressure, oil cooled, oil cooled on heavy pressure

conductors:                  The substance which is the least resistant in the flow of current and which is easily passed from the pedestal to the current, is known as the conductor, the conductor is also called the conductor. Copper, aluminum, iron, electrolyte etc. are metal conductors Insulator:                 The objects which are blocking the flow of currents in very high proportion, and from which the electrices can not pass through easily, are referred to as insulators. The inventor can also be called an insulator, Rubber, Asbestos, Bekalite, Mica, Ambonite, Wood , Etc. are known as insulators.

        Hello friends, we have many electrical or electrical equipment available everywhere, we use kahini electricity in the day, a large part of our entire life passes through electricity but we do not even know what electricity is ? How does he grow? It is said to be born? These questions arise in our mind but there is no one to answer them, so why have you come today in response to this question, let us know.  What is electricity? (What is electricity?):                               According to scientist J. Thomson, nothing is known only as electrons, ie that the flow of electrons is called electricity, electricity and electricity are the same, we can not see the electricity, but they can definitely feel, like Conversion of electricity to light, heat, magnetic and other physical effects. How Does Electricity Occur?                               Large generators are used for generating electricity and for the help of large turbines, water, air, and coal are us

          same  frequencies, a fixed part of the electronic instrument to convert the power from one circuit into another circuit, called a transformer, increases or decreases the voltage and decreases or decreases in the current with it. The value of the power remains the same during this process. That does not change the Transformer works on the rule of electrodynamic induction of Faraday Principle:               Transformer works on the theory of electromagnetism and electromagnetic induction. When two claws are held near them. And if one passes through AC coefficient, the second coil also has an emf indusus which is at the flux produced in the first coil. Based Formation:             The main part of the transformer is the core and the wing 1.Cor:             Transformer's core combustibles are made of slim straps of silicon steel, these stripes are laminated. These strips are more resistant to straps and less hysteresis losses. The thickness of these stri

The formation of this starter has been shown in the figure. We have seen that DC motors can not be combined with direct supply because the motor is damaged. To avoid this, the starter is used. We use the DC stator And we will now know about the DC4 point starter                                Its composition has been shown as shown in the figure. We can see that one end of the DC solution is given in overloaded relay, and given in the handle. It is arranged in accordance with the order of the motor of the motor through Resistance. .and the other end of the DC clearway is given directly to the other terminal of the motor, ie, the starter is attached to the motor series. The nvc coil is also found in the stator Holds the handle on the motor coming to the fullspeed                      Now when the collapse of the current supply falls, the magnetism of the nvc coil will be lost and the handle will come back into a closed position with the help of spring and the handle will not tu

                                 It can also be called a three point starter. Its structure is shown in Figure. To start the motor, the handle is moved from off position to the first contact position. The total obstacle is in the armature circuit, the field connection is connected directly to the supply through a volt coil. Comes in as soon as the speed of the motor increases in the same way as the archete back emf emits and decreases in the value of current Now the handle is moved to the second step. Again this type of function will be done eventually at the last step of the handle. This time the armature will connect directly to the supply and this time the handle does not come with a no-volt coil. The magnet will hold the handle in the walt coil, and the motor will not need to hold the handle to continue and the motor will rotate in full speed.                   Mechanism of 3 points Starter is done so that if the magnetism of the nvc coil is exhausted for any reason, and the
