Indoor substation single line diagram. When the magnetic field of a conductor that carries a current the primary coil moves across another conductor the secondary coil a voltage is produced in the second conductor by induction. 2 circuits 2800 m 3x1x1600 pose en galerie longueur 1300 m approx. The candidate should have experience with complex protective relay schemes in a high voltage substation. Instead of representing each of three phases with a separate line or terminal only one conductor is represented.
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. Jonction en galerie cable joint installation in gallery. Relay technician for our ohio office and field assignments. Transformers operate on the principle of induction as shown in below figure.
Electrical energy can be transferred. Installation in gallery length 1300 m approx. The main criterias to be considered during selection of one particular bus bar arrangement scheme. It carries electricity from the transmission system to individual consumers.
Single line diagram is a simplified notation for representing a three phase power system. There are many different electrical bus system schemes available but selection of a particular scheme depends upon the system voltage position of substation in electrical power system flexibility needed in system and cost to be expensed. Primary distribution lines carry this medium voltage power to.
