Vector group is a code used to represent the phase displacement and connection type of transformer windings.
Vector group determines the phase shift between the primary and secondary windings of a transformer.
It also indicates the connection type of the windings, such as Y-Y, Y-Δ, Δ-Y, or Δ-Δ.
The vector group code consists of a combination of letters and numbers, such as YNd11 or Dyn11.
The first letter represents the pr...
Three phase IM works on the principle of rotating magnetic field produced by three phase AC supply.
Three phase AC supply is given to the stator winding which produces a rotating magnetic field.
The rotor winding is short-circuited and the rotating magnetic field induces a current in it.
The interaction between the stator and rotor magnetic fields produces torque which rotates the rotor.
The speed of the rotor is slightly ...
Starters in 3-ph Im
Starters are used to control the starting and stopping of 3-phase induction motors.
Direct-on-line (DOL) starters are the simplest type of starters.
Soft starters and variable frequency drives (VFDs) are more advanced types of starters.
Starters protect the motor from overloading and overheating.
Starters also provide a means of reversing the motor's direction of rotation.

Materials are substances used to make objects. Their properties determine their usefulness.
Materials can be classified as metals, polymers, ceramics, and composites.
Properties of materials include strength, hardness, ductility, and conductivity.
Materials can be tested for their properties using various methods such as tensile testing and hardness testing.
The choice of material for a particular application depends on it...
