A thick peice of copper or alluminum that conducts electricricity within a switch board.
This seems like a question from an electrical course, and is probably best answered by referring to your course materials. It's your test question, not ours, and there won't always be someone else to ask for the answer. Earn your diploma.
Current transformer are used for measuring current in a bus bar without disconnecting it by means of ammeter.There are three types 1.bar type current transformer 2.toroidal current transformer 3.wound type current transformer
Busduct is useful for transforming current from switchgear end to transformer end.It has no voltage drop.But little bit expensive when compared to Cables.

Current transformers are found in power generation, electricity transmission & distribution, railways, industrial equipment, vessel propulsion, wind & solar renewables applications. In each application layer there are a number of sub-application levels for current transformers; for example, accurate measurement of power, protection of electrical plant, differential protection, restricted earth fault, isolated phase busduct, interposing, and summation.
