Current Transformer – Construction, Phasor and Errors
This article describes the current transformer – construction, Phasor, and Errors. Current transformers are widely used for measuring high currents. The Current transformer steps down
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
Thermistor: Definition,working principle and applications
What is a Thermistor? A thermistor is a type of thermal resistor whose electrical resistance increases or decreases with a change in temperature. Thus, the
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
