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 »

Distributions systems represent an important parts in the electrical grids and for this reasons the electrical generation & distribution companies delicate approximately 40% of the capital investment for distribution systems while the remaining is given to generation and transmission (40% generation & 20% transmission). The power distribution system is particularly important for an electrical utility… Read More »
In general understanding electrical distribution transformers are used to reduce primary system voltages (which is normally 2.4-34.5kV) to the level of utilization voltages i.e. 120- 600V. International electrotechnical commission standards do not distinguish between distribution electrical transformers and power transformer. They are all power electrical transformers in the sense that their purpose is to transmit… Read More »
