Definition of Switch Gears The devices used in switching, regulation, and protection of electrical circuits and equipment are installed in a panel board; these are collectively called switchgear. or switch gear meaning “The apparatus used for switching, Controlling and protecting the electrical circuits and equipment is known as Switch gear” Mainly switch gear equipment is … Read more
What is a DC Generator? A DC Generator is a machine that makes electricity. But not just any electricity — it makes DC electricity, which means Direct Current. Let’s make it super easy to understand. Imagine you have a toy fan that runs on batteries. The batteries give it power in one single direction — … Read more
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 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
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
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
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
