what is Transformer | Definition, top 2Types, Fact 0r construction
key phase Transformers work on the principle of mutual induction. They have primary andsecondary windings that are electrically isolated from each other. As these windingsare wound on the same magnetic core, they are magnetically coupled to each other. The magnetic core is made from the laminations of either CRGO silicon steel or theamorphous alloy. … Read more
Pvc Wire And Cable
PVC wires or PVC insulated wires, are electrical cables with insulation made ofPVC (Polyvinyl Chloride), a plastic material. These wires are commonly utilized in variouselectrical applications because of their exceptional insulation, flexibility, durability, and cost-effectiveness. Wire A wire is a thin, pliable, and elongated conductor composed of a conductivesubstance, usually metal, employed for transferring electrical … Read more
Universal motor – construction, working and characteristics
Introduction A universal motor is a special type of motor which is designed to run on either DC or singlephase AC supply. These motors are generally series wound (armature and field winding are in series), andhence produce high starting torque (See characteristics of DC motors here). That is why, universalmotors generally come built into the … Read more
Single Phase Induction Motor
Introduction Single phase power system is widely used as compared to three phase system for domesticpurpose, commercial purpose and to some extent in industrial purpose. As the single phase system ismore economical and the power requirement in most of the houses, shops, offices are small, this can beeasily met by single phase motor. The single … Read more
ALTERNATOR PRINCIPLES AND CONSTRUCTION
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
Three Phase Induction Motor: Types, Classification, Principle
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
What is an electric fuse? top 2 Type, Principle, and Working
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? Top 5 Types and working principle
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
Three-Phase Transformer: Construction, Principle, and top 5 Application
A Complete Introduction Three-phase transformers are passive machines that pass electrical energy between circuits. In the secondary circuit, a magnetic flux induces an electromotive force (emf), thus stepping up (increase) or stepping down (decrease) voltages without altering the frequency. Transformers are the unsung heroes of modern electrical power systems, silently stepping up or stepping down … Read more
