- Transformers are devices used in electrical circuits to change the voltage of electricity flowing in the circuit. Transformers can be used either to increase the voltage (called "stepping up") or decrease the voltage ("step down"). When electrical energy travels long distances in wires, some of the energy is lost.

To solve these issues transformers are used in power system. To avoid line losses and voltage drop in lines, transmission of electrical power carried out at maximum voltage. To step up voltage transformers are used in power system. Line losses (voltage drops) can be reduced by transmission of electrical power at higher voltages.
In the case of electrical utilities in homes, they use transformers to change the voltage of electricity as it travels from the power plant to your home. First using a transformer, the voltage of electricity coming from a power plant is “stepped up” to the right level for long-distance transmission.
Transformers help in stepping-up the generated power to ensure that the entire city receives electricity. Without the use of power transformers, power generated in the power stations would be insufficient for the entire city. Depending on their use, modern appliances have different requirements of voltage, which is supplied to them by the power transformers. Additionally, power transformers isolate the electrical device from the main power supply, thus protecting them from any damage or risk ...
High Voltage needs high Insulation Level- (Bigger Size More money) High current needs Bigger conductor size. (Bigger Size More money) hence Power is generated at neither high voltage nor high current/LV, but at MV-medium voltage. But transmitting ...
Transformers and Long-Distance Power Transmission Transformers are devices which use mutual induction to change the voltage and current of an AC circuit. A transformer with primary coil of Np turns and secondary coil of Ns turns will have ratios of voltage and current
A transformer is a device that uses the action of a magnetic field to change ac electric energy at one voltage level to ac electric energy at another voltage level. It consists of a ferromagnetic core with two or more coils wrapped around it. The common magnetic flux within the core is the only connection between the coils.
A transformer is a device that is used to either raise or lower voltages and currents in an electrical circuit. In modern electrical distribution systems, transformers are used to boost voltage levels so as to decrease line losses during transmission.
Electrical transmission is the process of delivering generated electricity - usually over long distances - to the distribution grid located in populated areas. An important part of this process includes transformers which are used to increase voltage levels to make long distance transmission feasible.
In short, transmission of power at high voltages can help achieving lesser power loss, lesser voltage drops and at the same time improves system efficiency and reduces overall cost of power transmission. Transformers are used for step up and step down of voltages in a power system. Read more about transformers.
The basics of power transformers in transmission and distribution grids. The methods of connecting windings will be the same, whether using the one three-phase transformer or three separate single-phase transformers. The two general methods of connecting three-phase transformers are shown in figure 1. The method shown in at figure 1a is known ...
Transformer used in the transmission of electrical power because they help to distribute electrical energy efficiently and can reduce transmission loss.
The Role of Voltage Transformers in Our Electric Power Systems. Transformers (sometimes called "voltage transformers") are devices used in electrical circuits to change the voltage of electricity flowing in the circuit. Transformers can be used either to increase the voltage (called "stepping up") or decrease the voltage ("step down").
Wye–Wye Connections of Transformer For high-voltage transmission systems, the use of the wye-connected transformer is more economical because the voltage across the phase of each winding is a factor of 1.73 less than the voltage between the lines. If the neutral point is grounded, there is no need to insulate it for the line voltage.
Power transformers, in association with distribution transformers, enable the transmission of electricity to any location. Power transformers receive electricity at extremely high voltages, which is stepped-down by the transformer to lower voltage levels that can be distributed through the distribution transformers to individual residential or commercial units.
