An aluminum or copper conductor supported by insulators
that interconnects the loads and the sources of electric
power in an electric power system. A typical application is
the interconnection of the incoming and outgoing
transmission lines and transformers at an electrical
substation. Bus-bars also interconnect the generator and
the main transformers in a power plant. In an industrial
plant such as an aluminum smelter, large bus-bars supply
several tens of thousands of amperes to the electrolytic
process. See also Electric power substation.
major types of bus bar
(1) Rigid bus-bars, used at low, medium, and high voltage
The rigid bus-bar is an aluminum or copper bar, which is
supported by porcelain insulators.
(2) Strain bus-bars, used mainly for high voltage
The strain bus-bar is a flexible, stranded conductor which
is strung between substation metal structures and held by
suspension-type insulators.
(3) Insulated-phase bus-bars, used at medium voltage
The insulated-phase bus-bar is a rigid bar supported by
insulators and covered by a grounded metal shield. The main
advantage of this system is the elimination of short
circuits between adjacent phases.
(4) Sulfur hexafluoride (SF6)-insulated bus-bars, used
in medium- and high-voltage systems
The sulfur hexafluoride-insulated bus-bar is a rigid
aluminum tube, supported by insulators and installed in a
larger metal tube, which is filled with high-pressure
sulfur hexafluoride gas.
According to size 3 types
* tubular bus bar
* solid bus bar
* flat bus bar
According to capacity 4 type
* Extra high voltage bus
* high voltage bus
* medium voltage bus
* low voltage bus

Good day everyone,currently in our premise we using 30kw slip ring motor with resistance bank which we use as forward and reverse at conveyor bar handling. So,my question is how do we calculate the resistance bank which is suit the motor. Kindly,assist me... thank you
