Turn Ratio & Voltage Transformation Ratio of Transformer
This article describes two important transformer ratios: turn ratio and voltage transformation ratio. Transformers are fundamental components in electrical engineering, playing a crucial role in
What is a Step Up Transformer?
Definition: A step-up transformer transforms the low voltage on the primary side to the high voltage on its secondary side. The current on the secondary
Induction Motor: Working Principle, Types & Definition
What is an Induction Motor? An induction motor, also known as an asynchronous motor, is a type of AC electric motor that is widely used.
Armature Reaction in DC Machine
Understanding how magnetic fields interact inside a DC machine is crucial for optimizing performance and preventing losses. One such phenomenon is the armature reaction —
What is an Auto Transformer?- Working, Diagram, Advantages
An auto transformer is a special type of transformer that works on the same principle as a two-winding transformer but uses only one winding for
Transformer Core Saturation and Its Reasons
When a magnetic core reaches its limit in carrying the magnetic flux, it is called the core saturation in a transformer. This occurs when the
Power Flow Diagram and Losses of Induction Motor
An induction motor’s power flow diagram and loss analysis show how electrical power is converted into mechanical power, and the losses occur at various stages
Characteristics of DC Series Generator (Series Wound DC Generator)
The three main characteristics of a DC series generator are used to analyze its operating behavior. By studying these characteristics, we can establish the relationship
