## Introduction of Distribution Electrical Transformers – How Transformer Works?

In general understanding electrical distribution transformers are used to reduce primary system voltages (which is normally 2.4-34.5kV) to the level of utilization voltages i.e. 120- 600V. International electrotechnical commission standards do not distinguish between distribution electrical transformers and power transformer. They are

## Electric Current Electric Charge & Electromagnetism

Very basic question which an electrical student or professional may be asked is what is electric current and electric charge. The electric current is actually the flow of electric charge from one point to other point of the conductor or wire or cable.

## Ideal Transformer Equations

An ideal transformer is a theoretical, linear transformer that is lossless and perfectly coupled; that is, there are no energy losses and flux is completely confined within the magnetic core. Perfect coupling implies infinitely high core magnetic permeability and winding inductance and zero

## Sinusoidal Voltage Equation

A sinusoidal voltage can be described by the equation: v(t) = VM sin (ωt + Φ) or v(t) = VM cos (ωt + Φ) where v(t) Instantaneous value of the voltage, in volts (V). VM Maximum or peak value of the voltage,

## Introduction of Control Engineering | Closed Loop Open Loop Control Systems

Control system engineering is the branch of engineering which deals with the principles of control theory to design a system which gives desired behavior in a controlled manner. A controlled system consists of highly integrated coordination of mechanical, electrical, chemical, metallurgical, electronic or
