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
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
Introduction to Single-Phase Transformers Introduction to Single-Phase Transformers Why Are Single-Phase Transformers Important? Construction of a Single-Phase Transformer Core Assembly Winding Configuration Insulation System Core Materials and Design Insulation System Working Principle of a Single-Phase Transformer Fundamental Operating Concept EMF equation for 1ø transformer: – Types of Single-Phase Transformers Core-Type Transformers Shell-Type Transformers Step-Up Transformers … Read more
What is a Molded Case Circuit Breaker (MCCB)? A Molded Case Circuit Breaker, or MCCB switches, is like a guard for your electrical system. It watches over your wires and machines and quickly stops the power if something goes wrong—like when too much electricity flows or when there’s a short circuit. This helps keep your … Read more
Transformer Safety: Transformers play a big role in powering our industries. They help move electricity safely and efficiently. They are helpful in many ways, but if not used properly, they can also cause harm Working with transformers can lead to serious risks. Electric shocks, arc flashes, and even fires or explosions can happen if safety … Read more
Introduction Electrical power system को समझने के लिए transformers का knowledge होना बहुत जरूरी है, क्योंकि यही devices generation से लेकर end user तक electricity को सही तरीके से पहुँचाने का काम करते हैं। खासकर Difference Between Power And Distribution Transformer को समझना बहुत important है, क्योंकि ये दोनों transformers अलग-अलग stages पर अलग-अलग काम … Read more
पावर फैक्टर (Power Factor) क्या होता है पावर फैक्टर (Power Factor) क्या होता है या किसे कहते हैं? इसे सरल या आसान भाषा में elentechpk के साथ समझें तो पावर फैक्टर (Power Factor) वह माप होता है जो यह प्रदर्शित करता है कि हमारा इलेक्ट्रिक सिस्टम source द्वारा ली जाने वाली कुल power (apparent power) … Read more
