What is Short Circuit Current? - Definition and its Process: Whenever a short circuit current occurs in a power network, it causes heavy current to flow in the network. Figure…
Different Types of Faults in Power System: A fault in an electrical equipment/apparatus is defined as a defect in the electrical circuit due to which current is diverted from the…
Speed Control of Three Phase Induction Motor: The problem of speed control of three phase induction motor in particular is of great practical importance. In a number of industries motors…
Counter Emf Automatic Starter - Working Principle and its Drawbacks: This type of starter depends upon the build up of the back or counter emf to operate the contactors (a…
Starting of Electric Drives: The most important processes associated with controlled electric drives are (i) starting, (ii) speed control (iii) braking, (iv) reversal of direction of rotation. All these are…
Repulsion Motor - Construction, Working Principle and Applications: The characteristics of repulsion motors are similar to those of a series motor, i.e., high startÂing torque and high light-load speed. Its…
Permanent Capacitor Single Phase Induction Motor: Permanent capacitor single phase induction motor, also sometimes called the single-value capacitor—run motor, has two stator windings placed mutually 90 electrical deÂgrees apart. The…
Capacitor-Start Capacitor-Run Single Phase Induction Motor: The capacitor-start capacitor-run motor is similar to capacitor-start, induction-run motor, except that the auxiliary winding and a capacitor remain connected in the circuit at…
