Basic Alternator Working Principle: WHAT IS ALTERNATOR? Alternating current generators are usually called alternators. They operate on the principle ofFaraday’s laws of electromagnetic induction. This law states that whenever a conductor cuts the magneticflux an emf is induced in it. This emf causes a current to flow if the circuit is closed. Fig 1.1 shows … Read more
INTRODUCTION In the year 1821 British scientist Michael Faraday explained the conversion of electrical energyinto mechanical energy by placing a current carrying conductor in a magnetic field which resulted in therotation of the conductor due to torque produced by the mutual action of electrical current and magneticfield. Based on his principle the most primitive of … Read more
Fuse An electrical fuse is a simple device used to interrupt an electrical circuit during over currentcondition due to short circuit and/or overload. An electrical fuse operates on the principle of heatingeffect of electric current. During normal operating condition, the current flowing through the fusingelement is such that the rate of heat production in the … Read more
What is a Circuit Breaker? A circuit breaker essentially consists of fixed and moving contacts, called electrodes. Undernormal operating conditions, these contacts remain closed and will not open automatically until andUnless the system becomes faulty.The contacts can be opened manually or by remote control whenever desired. When a fault occurs on anypart of the system, … Read more
