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 »
Generally there are two power transmission and distribution systems that are used to transmit electrical energy i.e. HVDC or High Voltage Direct Current transmission system and HVAC or High Voltage Alternating Current transmission system. Now let’s see the advantages and disadvantages of both power distribution systems. COMPARISION OF HVAC & HVDC SYSTEMS HVAC transmission is… Read More »
The distribution of current throughout cross section of a conductor is uniform only when DC is passing through it. When Alternating Current(AC) is passing through a conductor, the current is non uniformly distributed over the cross section in a manner that the current density is higher at the surface of the conductor compared to the… Read More »
Being an electrical engineer on a construction project is a very tedious and responsible job. Electrical site engineer is wholly responsible for the ordering of materials as per the pre approved material submittals and an electrical project specifications. Here in this article we have included the complete list of testing requirements for an electrical system… Read More »
As an electrical engineer or professional you already know that an electrical or distribution substation is very important components of any power distribution system. Normally electrical grid can be considered as simple circuit which includes power source or generation, power transmission and electricity distribution lines for connecting to the electricity consumers. The role of electrical… Read More »
