Transmission line modelling, contacts, bolted
connections, making decision
In electrical power transmission and distribution systems
we find a lot of contacts between conductors. These
contacts have to carry currents of hundreds or thousands
of Amperes for many years without any revision. The
process of designing flat bus-bur contacts is complex. A
great many design parameters may be varied
independently, and the balance between cost and quality
is often a matter of trial and error. The weighted
correlation analysis described here has been found to be a
useful method of tackling the problem systematically.
Some exemplary application of the weight-correlation
method has been included.
