Direct current or DC machines are used for the conversion of one form of energy to another. Similarly a DC Generator is used to generate the energy which works on the principle of converting mechanical energy into electrical energy. Basic law or principle behind the generator is the Faraday’s law of electromagnetic induction which states that… Read More »
Resistance definition & Meaning Understanding of resistance is very basic requirement for electrical engineers or professionals, the question of resistance comes when we are talking about the conductors, metals, wires or cables etc. Electrical resistance in general is a measure of the difficulty to pass through electric current from any conductor. So in simple words we can… Read More »
What is MCB? MCB or Miniature Circuit Breakers is a mechanical switching device which is capable of making, carrying and breaking currents under normal circuit conditions and also making, carrying for a specified time and automatically breaking currents under specified abnormal circuit conditions such as those of short circuit. So we can say that MCB… Read More »
What is an ELCB? An Earth Leakage Circuit Breaker (ELCB) is a safety device used in electrical installations with high earth impedance to prevent shock. It detects small stray voltages on the metal enclosures of electrical equipment, and interrupts the circuit if a dangerous voltage is detected. Once widely used, more recent installations instead use… Read More »
Before discussing the types and importance of busbar protections let’s see what is a bus bar? The word bus is derived from Latin word “OMNIBUS” that means common for all, so busbar is actually a common and main part of a power distribution system that serves as nerve center of the power system where various… Read More »
What is Electricity? Electricity is a form of energy that can be easily changed to other forms. Electricity comes mainly from 2 sources i.e. Power stations and generators that supply a lot of electricity and normally used in many electrical appliances and industrial applications. From Electric Cells or batteries which are used for portable purposes. To… Read More »
