Question

what are:
bus extensions?
bus bar?
bus raiser?
bus section?

Answer 1

Bus Extesion: Bus Extension is data bus that help to extend the reach of data to end node. for ex. The internal information bus extension is used to increase a fieldbus node and primarily consists of an internal data bus extension finish module and a minimum of one and up to 10 internal data bus extension coupling modules.

BusBar: In electrical power distribution, a busbar (also bus bar, and generally misspelled as buss bar or bussbar) is a metallicstrip or bar, typically housed within switchgear, panel boards, and busway enclosures for local high current power distribution. they're also used to connect high voltage instrumentation at electrical switchyards, and low voltage instrumentation in battery banks.

Bus Riser: Bus riser is a set of bus bar that connected from the coupling breakers, outgoing section enclose within the panel and connected to your incoming one or incoming a pair of bus bar section. It rely that side is your outgoing from the bus bar coupler breakers or depend upon your electrical style.

Bus riser is used in between 2 buses at same level connected with a fuse known as bus coupler.In this system one bus is connected with higher portion of the breaker and lower portion or output of fuse is connected to bus riser who works to rise the bus on level of 1st one.

Bus Section: The bus section is used in switchgear having one conductor Configuration to divide the bus into 2 Sections. i.e Bus section is section between single bus ( bus section is mean section A and B)
