A transformer or transformer is an electrical machine with no moving parts which is used to transform the level of voltage in AC systems by magnetic induction without changing the frequency.
Transformers are generally used in the transmission and distribution of energy. During the transmission of electrical energy from power plants to the usage areas, power loss and voltage drop occurs in the form of heat in the lines. To minimize this, the power must be kept constant and the voltage increased. This means that the current is reduced. Thus, the cross-sections of the conductors used in the lines are reduced, losses are reduced and the conductor cost and thus the transmission costs are reduced.
In general, transformers are used to reduce or increase the voltage or current in an electrical circuit. In electronics, it is mainly used to connect amplifiers in different circuits, convert direct current waves to alternating currents at a higher value, and transmit only certain frequencies. It is used for insulation purposes and sometimes with capacitors and resistors. In electrical current transmission, it is mainly used to raise or lower the voltage. Special transformers are used in measuring instruments.
Transformer, which is a transformer, is an electrical device used to transform the level of voltage in alternating current systems by magnetic induction method without changing the frequency. Generally, transformers used to transmit and distribute energy do not have a moving part. While electrical energy is transmitted from power plants to areas of use, lines generally lose power in the form of heat and voltage drops. In order to keep this situation at the lowest level, the power must be kept constant and the voltage must be increased. This also means that the current is reduced. In this way, the cross-sections of the conductors used in the lines are reduced, energy losses are reduced and transmission costs are reduced. At this point, transformers are used to increase or decrease the current in an electrical circuit. Transformer briefly; It is a stationary alternating current machine that converts it into electrical energy. During this energy conversion, the factors of power are; it serves to change voltage and current. For example, we convert 220 V mains voltage to 12 V alternating voltage with a transformer. There are at least two or more coils in the structure of the transformer. In this matter, we will test that not only transformer windings complete the circuit, in other words, their coils. After the circuit is de-energized, we will test the multi-meter by placing the Ohm meter position and matching the Ohm meter leads to each coil of the transformer. If the Ohm meter shows the value for each transformer coil (often less than 1000 Ohm), it will mean no disconnection in the transformer windings. In addition, there should be no transmission (leakage) between the windings. For this, the Ohm meter must show no value (infinite resistance) between any two ends of the two coils of the two transformers.
The transformers consist of a closed magnetic body consisting of very thin but very stable siliceous sheets consisting of silica, oxygen and silicon and insulated conductor windings wound on the body. Since transformers do not have moving and rotating parts, they do not have losses due to friction and similar reasons. As such, it is extremely efficient compared to other electrical machines. For the operation of vehicles such as radio, television and door bells, the voltage of 220 volts must be reduced to 8, 10, 12 volts. Transformers provide this. In addition, while the electrical energy received from the alternators is transported to very remote locations, heat losses in the transmission lines should be reduced. Transformers are used for very small current intensity and high voltage. Then, the voltage is reduced again and the energy is transported without loss. In addition, transformers are used in hospitals, laboratories and factories.
