Magnetic field management is concerned with the minimization of the effects
of such fields on the public health, without sacrificing the effectiveness
or reliability of the power system. The essential management techniques us
ed for the underground transmission cables comprise geometry manipulation p
hase placement, and source shielding. In this paper, the simulation results
of the standard recommended stack, triangular and flat configurations are
presented. The simulations have been carried out for single and three phase
cables. The resulting fields for different depths have been evaluated and
compared. The results led to the conclusion that judicious placement of pha
ses is a very powerful management technique to reduce the magnetic field as
cost has not been changed. The appropriate phase placements corresponding
to minimal field values are obtained. (C) 1999 Elsevier Science S.A. All ri
