Why is a transformer used to connect a generator in a power station to a long distance transmission line?
At a power plant, a transformer increases the voltage of generated power by thousands of volts so it can be sent of long distances through high-voltage transmission power lines. … At substations, transformers lower the voltage of incoming power to make it acceptable for high-volume delivery to nearby end-users.
What is the purpose of a transformer?
A transformer is a device that transfers electric energy from one alternating-current circuit to one or more other circuits, either increasing (stepping up) or reducing (stepping down) the voltage.
What is the relationship between a generator and a transformer?
Generator and Transformer: An Introduction
These two devices work based on Faraday’s law of electromagnetic induction principle. The “Generators” generate current, and transformers convert between current and voltage.
Can you use a transformer with a generator?
The power transformers involved can be divided into three basic subgroups based on their specific application: … Station service transformers (SST) that connect the system directly to the generator auxiliary load. Unit auxiliary transformers (UAT) that connect the generator directly to the generator auxiliary load.
How does a transformer work?
A transformer is an electrical apparatus designed to convert alternating current from one voltage to another. … When voltage is introduced to one coil, called the primary, it magnetizes the iron core. A voltage is then induced in the other coil, called the secondary or output coil.
