Advantages of Parallel Operation of Transformers
Parallel operations of transformer: Definition-Connection of the primary winding of two transformers to a common supply voltage and connection of the secondary winding of both
Machines
An electrical machine converts mechanical energy into electrical energy or vice versa. The transformer is also an electrical machine which transform the voltage without changing the frequency. We will discuss about the;
- DC Motor
- DC generator
- Induction Motor
- Transformer
- Electrical drives
- Alternator or synchronous generator
How to Change the Direction of Rotation of DC Series Motor?
In this post, we will discuss how to change the direction of rotation of the DC Series Motor. The rotational force of the DC motor
What is no load Current of Induction Motor?
The current drawn by the induction motor when it is not coupled to the driven equipment is called the no-load current of the motor. The
Current Transformer – Construction, Phasor and Errors
This article describes construction of current transformer(CT) , CT Phasor and Errors. Current transformers are widely used for measuring high currents. The Current transformer steps
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
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
