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 »
Single Phase power circuits Single phase electric power or circuit refers to the distribution of alternating current electric power using a system in which all the voltages of the supply vary in corresponding exactly. Single-phase distribution is used when loads are mostly used for the purpose of lighting and heating which can also be for… Read More »
What is a Diode? Di+Ode is a semiconductor device with two terminals allowing the flow of current in one direction only, diodes are made up of Silicon, Germanium & GaAs. The perfect diode would be a perfect conductor in one direction (forward bias) and a perfect insulator in the other direction (reverse bias). In many situations, using… Read More »
