Transmission line voltage levels in india

Electric power distribution is the final stage in the delivery of electric power; it carries electricity from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 35 kV with the use of transformers. Siemens has proven to be a reliable, trustworthy supplier of high-voltage substations for all voltage levels and for all applications – from basic substations with a single busbar to interconnection substations with multiple busbars or a breaker-and-a-half arrangement for up to 800 kV, 8,000 A, and short-circuit currents of up to 100 kA.

The investment for the project is estimated at Rs 800 crore. The high transmission capacity of the HVDC lines, combined with lower requirements on conductor bundles and air clearances at the higher voltage levels, makes the HVDC lines very cost efficient compared to EHVAC lines. The cost advantage is even more pronounced at the highest voltage levels. Transmitting electricity at high voltage & extra high voltages reduces the fraction of energy lost to resistance, which varies depending on the specific conductors, the current flowing, and the length of the transmission line.

The high voltage transmission has some advantages as compared to low voltage and high level of current transmission i.e. low power factor, corona loss, skin effect, l 2 R (Line losses), Heat etc. The only disadvantages of high power transmission is distance, insulation of the line and height of towers. i) Overhead transmission lines transmit 3Φ AC power over long distances (300 miles or less) and at high voltages. Common voltage levels range from 115 kV to 765 kV. ii) Underground transmission lines are buried in trenches, in conduits, or in vaults, and often cooled. See full list on electrical4u.com For river crossing of 132 KV, 220KV and 400 KV transmission lines, the following conductors are being used in UPSEB:- For 132 KV Lines: Special 'Panther' conductor, i.e. one Aluminium layer of ACSR 'Panther' conductor removed having 7-strands of Steel of 3.00 mm dia plus 12-Aluminium strands of 3.00 mm dia. For 220 KV Lines: Extra high voltage (EHV; transmission) – over 230 kV, up to about 800 kV, used for long distance, very high power transmission. Ultra high voltage (UHV) – higher than 800 kV. How to identify voltage level of a powerline Transmission lines move large amounts of power at a high voltage level – a level that is too much to be delivered directly to a home or business. Transmission lines, transformers, substations and other equipment have voltages of 100 kV (100,000 volts) and above. Explore the history and value of the transmission system. Electric power distribution is the final stage in the delivery of electric power; it carries electricity from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 35 kV with the use of transformers. Electric power distribution is the final stage in the delivery of electric power; it carries electricity from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 35 kV with the use of transformers. So supply side transformers step up the generation voltage at TG end (Normally 25 kV) to 400 or 765 kV. At this voltage current carried by line reduces, thereby reducing heat loss and efficient transfer of power over long distances. At utility end Grid or switchyards reduce the voltage to 220 kV or lower for short distance consumer distribution.
