What is a switching station? A switching station is a substation that does not contain power transformers and therefore does not change system voltage from one level to another. Switching stations usually operate at sub-transmission or transmission voltage levels. Depending on system voltage, the equipment types and characteristics used in switching stations are … [Read more...] about What is Switching Station? | Working and Layout

Bundled Conductors in Transmission Lines
The combination of more than one conductor per phase in parallel suitably spaced from each other used in an overhead transmission line is defined as a bundled conductor. The individual conductor in a bundle is defined as a sub conductor. Bundled conductors in transmission lines are commonly used to increase electrical capacity and reduce corona and radio noise at voltages … [Read more...] about Bundled Conductors in Transmission Lines
