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 »
It is well known that Circuit Breakers are devices which are used to break a circuit continuity and restore it again when required. Normally these are known as switching devices that can be activated manually or automatically to control the electrical power systems. In case of short circuiting or leakage of the larger amount of… Read More »
