Why is armature of alternator connected in Star not in Delta?
The alternator armature winding must be protected from earth faults. The earth fault protection scheme for an alternator whose armature winding is connected in a
EMF Equation of Alternator and AC Generator
An alternator or AC generator produces an AC supply. In other words, the generator or alternator converts mechanical energy into electrical energy. The rotor rotates
Direction of Rotation of DC Motor
The Direction of rotation of the DC Motor can be reversed by reversing the direction of torque of the motor. When the motor exerts torque
Why Three Phase Induction Motor Self-Starting?
When a three-phase supply is fed to the stator of an induction motor, the stator draws current from the 3-phase supply, which produces the magnetic
What is Skin Effect? Factors affecting the skin effect
When the DC current flows through the conductor, the charge distribution throughout the conductor cross-section is uniform, and the current gets evenly distributed. Direct current
Ferrite Core Transformers- Types & Applications
What are Ferrite Core Transformers? Ferrite core transformers are made from ferrite materials. The ferrite core transformer is used for higher-frequency applications. The power transformer is
Working or Operating Principle of DC Motor
The DC motor converts electrical energy into mechanical energy. The input power to the DC motor is DC power. The DC motor works on the
Interharmonics in Power System
Power electronics are widely used nowadays to improve system efficiency, flexibility, and reliability. The semiconductor devices used in power electronics are nonlinear devices, and the
Torque Equation of DC Motor- Its Derivation
When the current-carrying conductor is placed in the magnetic field, the conductor experiences a force that exerts a turning moment or torque F x r.
