Mathematically we can define an Idempotent matrix as A square matrix [A] will be called an Idempotent matrix if and only if it satisfies the condition A2 = A. Where A is n x n square matrix.
Following are the various parts of the transformer:
Terminals and bushings
Radiator and fans
Star-delta starter is the most commonly used reduced voltage starting method for starting a medium HP 3-phase squirrel cage induction motor (SCIM). It is also known as a wye-delta starter.
An Involutory matrix is simply a square matrix that when multiplied itself will result in an identity matrix. In other words, mathematically we can define an involutory matrix as: If A is a square matrix then matrix A will be called an involutory matrix if and only if it satisfies the condition A2 = I. Where I is n x n identity matrix.
In this article, we are going to discuss some important Transformer interview questions and their most appropriate answers. If you …
