What is vector group of transformer?

Vector Group of Transformers                     • A vector group is the International Electrotechnical Commission (IEC) method of categorizing the high voltage (HV) windings and low voltage (LV) winding configurations of three-phase transformers.                      • Vector group is a connection of primary winding , secondary winding and an electrical angle difference .                      • The vector group designation indicates the windings configurations and the difference in phase angle between them. The three phase transformer windings can be connected several ways. Based on the windings’ connection, the vector group of the transformer is determined. •              The transformer vector group is indicated on the Name Plate of transformer by the manufacturer. The vector group indicates ...

Hosh Mohammed Sheedi

                 Sheedi , Hush Mohammed: The famous Surmo of Sindh and General Hoshu Sheedi, who chanted the slogan of 'Mursun Murson Sindh na Disson', have passed away during the Talpur period. Hoshu Sheedi , Talpur ruler Mir Fateh Ali Khan Talpur was an army soldier for military purposes. There have been several Anak soldiers in South India and Delhi Government. Alana, the renowned writer, writes the year 1801, the birth of Hoshu Sheedi. However, the birth of Seal Kathilvi Hoshu Sheedi is estimated in 1782 AD. According to William Napier, Hoshu learned the art of Tobacchi from the French armies, who were among the leading European subjects trained in various states of Mysore and Punjab, India during that period.                Hoshu Sheedi appeared in the court of Sindh in 1811. At that time the ruler of Sindh was Mir Fateh Ali Khan Talpur. Hoshu's son , Mir Fateh Ali Talpur's son Mir Subedar Ali and ...

What is Capacitor?

             Capacitor is a basic electrical component that stores charge.It is constructed of two parallel conductive plates separated by insulating material called dielectric.Connecting leads are attached to parallel plates.                Lets consider initially capacitor is in uncharged (Neutral) state.In neutral state both plates of a capacitor have an equal number of free electrons.Electrons are removed from plate A and equal number of electrons are deposited on plate B. Plate A becomes positive and Plate B becomes negative. During charging, no electrons flow through dielectric because its an insulator,The movement of electrons is ceased when voltage across the capacitor equals to source voltage.  Now if capacitor is disconnected from source, it retains charge and still it has voltage across its terminals.Charged capacitor acts as a temporary battery.            ...
