What is the function of transformers in the electrical system?
Electrical power system transformers are essential for adjusting voltage levels to ensure efficient transmission and distribution of power. They increase voltage levels for transmission over long distances, which reduces energy losses due to the resistance of power lines.
At the receiving end, transformers step down the voltage to safer, usable levels for distribution to homes and businesses. This function helps maintain the balance between production, transmission and consumption of electrical energy.
The main function of a transformer in an electrical system is to change the voltage level between circuits while maintaining the same frequency. This voltage adjustment is achieved without changing the power (except for minor losses), enabling efficient delivery of electrical power over various distances and applications.
By changing voltage levels, transformers help reduce electrical losses during transmission and ensure that the voltage delivered is suitable for different types of electrical devices and equipment.
Power transformers are used in various parts of the electrical system to manage and control voltage levels.
They are commonly found in substations, where they step down high transmission voltages to lower levels suitable for distribution in residential and commercial areas. Power transformers are also used in industrial plants to adjust the voltage levels of large machines and in power plants to adapt the generated voltage for transmission purposes.
The operating principle of a power transformer is based on electromagnetic induction. It consists of two or more spools of wire wound around a common core.
When alternating current (AC) flows through the primary coil, it creates a varying magnetic field which induces a voltage in the secondary coil. The ratio between the number of turns in the primary and secondary coils determines whether the transformer increases or decreases the voltage.
This process is efficient because it is based on the principle of induction rather than direct electrical contact.
Types of power transformers include:
What is the main function of an electrical transformer?
Distribution Transformers: Used to reduce voltage for use in homes and businesses.
What is the purpose of a transformer?
Power Transformers: Handle higher voltages and are used in transmission substations to increase or decrease voltage levels for long distance transmission.
Auto-Transformers: Allow voltage adjustment with a single winding that serves as both the primary and secondary coil.
Instrument transformers: Include current transformers (CT) and potential transformers (PT) for measurement and protection purposes.
