The excitation system of alternator is a critical component responsible for supplying the necessary field current to the generator’s rotor winding. This field current creates a magnetic field, inducing voltage in the stator windings, thus producing electrical power.
A star delta starter, also known as a Wye-Delta starter, is an electrical control circuit used to start and control the speed of three-phase induction motors. It is widely employed in various industries where motors with high power ratings are used, such as manufacturing plants, refineries, and mining operations.
A cathode ray oscilloscope (CRO), also known as an oscilloscope or scope, is a widely used electronic test instrument that allows you to visualize electrical waveforms. It is particularly useful in the field of electronics, telecommunications, and physics for observing and analyzing various types of electrical signals.
The stator and rotor play crucial roles in the functioning of motors, generators, and other rotating machinery. Understanding these components is essential for comprehending the principles behind their operation and their applications in various industries.
SCR stands for Silicon Controlled Rectifier. It is a type of semiconductor device that belongs to the family of thyristors, which are widely used in power electronics. An SCR is a four-layer, three-terminal device with three pn-junctions. The three terminals of an SCR are the anode (A), the cathode (K), and the gate (G).
