A coaxial cable can be used to reduce the magnetic and electric fields
that extend into environments in the vicinity of transmission lines a
nd distribution lines and in-house or building wiring for power distri
bution systems. The use of the coaxial geometry map prove useful in ca
ses where there are environmental concerns with respect to health effe
cts and in cases where there is a need to run high-speed data communic
ations in close proximity to power distribution systems. (C) 1996 Wile
