HVDC Transmission Definition : High voltage direct current (HVDC) control frameworks use D.C. for transmission of mass control over long separations. For long-separate power transmission, HVDC lines are more affordable, and misfortunes are less when contrasted with AC transmission. It interconnects the systems that have diverse frequencies and attributes.  In a transmission, exchanging rushes of voltage and current goes in the line which alters its course every millisecond; because of which misfortunes happen as warmth. Not at all like AC lines, the voltage and current waves don't alter their course in DC. HVDC lines increment the productivity of transmission lines because of which control is quickly exchanged.  In a joined AC and DC framework, created AC voltage is changed over into DC at the sending end. At that point, the DC voltage is upset to AC at the less than desirable end, for dispersion purposes. In this manner, the change and reversal hardware are likewise...

Sub-Station It is a conversion point between transmission-level voltages (such as 138 kV) and distribution level voltages (such as 11 kV). A substation has one or more step down transformers and serves a regional area such as part of a city or neighborhood. They are connected to each other by a transmission ring circuit. Equipment and its function 1). Lightening Arrestor This is the first component in an electrical substation, and the principle capacity of these segments is to shield the segments of the substation from passing high voltage just as stops  the amplitude and duration of the flow of current . The light arrestor segments are associated among the earth just as a line which mean parallel to the parts under resistance at the electrical substation.    Bushings and Lightning Arrestor These parts divert the flow of current to the ground and hence secure the framework's conductor just as protection from damage. Th Lightning Arrestor does no...
