What is the function of the exciter in a generator?
The function of the exciter in a generator is to provide the initial electrical current necessary to create the magnetic field in the rotor. This magnetic field is essential for the generator to produce electrical energy. The exciter is essentially a smaller generator that provides excitation current to the rotor windings, which in turn induces a magnetic field necessary for the main generator to operate.
In a synchronous generator, the exciting field plays the crucial role of supplying direct current (DC) to the rotor windings. This direct current creates a magnetic field that interacts with the stator windings to generate alternating current (AC). The exciter ensures that the generator maintains a stable output voltage by regulating the amount of excitation current supplied to the rotor.
What function does the exciter field perform in a synchronous generator?
An exciter works by converting a small amount of mechanical energy into electrical energy, which is then used to power the rotor windings of the main generator. This process involves the exciter generating direct current, which is sent to the rotor to create the magnetic field necessary to induce voltage in the stator windings.
How does an exciter work?
An excited generator refers to a generator that has an excitation system in place. The excitation system provides the necessary current to the rotor windings to produce a magnetic field, allowing the generator to produce electrical energy. The term “excited” highlights the presence of this excitation mechanism, essential to the operation of the generator.
An electric exciter is a device that generates the electric current necessary to produce the magnetic field in the rotor of a generator. It is usually a small generator that converts mechanical energy into electrical energy. This electrical energy is used to excite the rotor windings, thereby facilitating the generation of electrical energy in the main generator.
