“Thanks for reading! Follow Tack Knowledge for more updates.”                           Introduction In the modern world, electricity powers almost everything we do — from the light in our homes to the machines in industries. But along with its benefits, electricity also comes with risks like electric shock, fire hazards, and damage to appliances. That’s where electrical earthing comes in. Earthing (also called grounding) is the process of connecting the non-current-carrying parts of electrical equipment or the neutral point of a power system to the earth. This ensures that in case of a fault, excess electrical energy flows safely into the ground instead of causing harm. This guide will take you through the various types of earthing, their importance, applications, and benefits—all written in a human-friendly style and optimized for search engines.              What is Electrical Earthing...

Circuit breakers are crucial components that interrupt fault currents and protect equipment. Among various types of circuit breakers, the Vacuum Circuit Breaker (VCB) stands out due to its excellent arc-quenching properties, long life, and minimal maintenance. This blog explores the working principle, construction, advantages, disadvantages, and applications of VCBs in detail. --- Main Content : What is a Vacuum Circuit Breaker (VCB) ? A Vacuum Circuit Breaker is a type of circuit breaker where vacuum is used as the arc-extinguishing medium. When the circuit breaker interrupts the current, the arc that forms between the contacts is quickly extinguished due to the high dielectric strength of the vacuum. --- Why Vacuum? Vacuum has no ionized particles, so it provides excellent insulation. The arc disappears quickly b...
