Bus duct is a group of busbars meged togother whereas bus
bar is a rigid peice of copper or aluminium that conducts
electrical power in effective way , and bus duct is used
for big power transfer.

Answer / x man

Bus duct can also be called as BusBar Chamber where all the
bus bar to the loads are assembled.

BusBar is Copper strip sized in different dimensions
depending on the current rating&short circuit rating of the
load.
their dimensions will be in width and thickness.

Answer / annu singh

bus buct is a chamber in which contains bus bars for
transfer electric power. and bus bar is may be copper/
alluminium bars which is used as a current carrying
conductor. bus duct is normally used for safe wperation for
power transfer for few distance.

Answer / thiag

Busbar:

Its the rigid conductor used inside the electrical panel for distribution of electrical supply inside electrical panel between incoming circuit breaker to outgoing circuit breaker.

Bus duct:

Its also a rigid conductor used to transfer electrical power from one electrical panel to another electrical panel. Busduct is used where there is a large amount of current transfer(approx 400A +)required.It shall used instead of cables.

Answer / ashish malik

Bus duct are the hollow conductors used to transfer electrical power and used for high current .These are hollow because flow of the high current exhibits small amount of current passing through the middle of conductor due to skin effect . As to save conductor material and cost these are made to be hollow .

Answer / sathiyaseelan

Bus bar means inside the panel board(R,Y,B,&N). Bus duct
means transformer output and panel input(R,Y,B,&N) this
between connection called bus duct

we have a 2000kva step down transformer at our site. The HT side is charged from 22000V. So the primary current will be 52.48A. So why the HT breaker(SF6 ABB) is rated of 1250Amps ?

We use ungrounded DC system (220V/110V) for control and protection system in substations etc. Suppose we have long 2 core DC cables running from our DCDB in control room to the load (length of around 2 to 3 km). Do we need to protect these long DC cables from earth leakages or not? If yes how?
