Peace and blessings be upon the one after whom there is no other prophet and upon whom revealed the Holy Quran.  Dear readers, at first take my cordial salam, Assalamualaikum (peace be upon all of you).  Today, I would like describe about Electrical Energy. Let's know first what is Energy? Energy: In physics, energy is the quantitative property that must be transferred to an object in order to work on or heat the object. Energy is an conserved quantity. The conservation of energy states that, energy can be converted in a form to other form but it neither be created nor destroyed. The SI unit of energy is the Joule. If 1 newton force apply on an object and it move 1 meter, then in this case the consumed energy is called 1 joule.  Energy is the basic necessity of for ...

Definition: A substation is a part of electrical energy generation, transmission, and distribution system. Substations transform voltage from high to low, or low to high, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels. A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two different transmission voltages.  Type of Sub-Station: The majority of the sub-stations in the power system are concerned with the changing of voltage level of electric supply. These are known as Transformer Substation because transformer is the main component employed to change the voltage level. Depending upon the purpose served, Transformer Substation may be classified into: 1.     Step-up sub-station 2.     Primary grid sub-stati...
