| Abstract |
Lightning strikes creates damages to the electrical power system utilization and
equipment. To reduce the effect of lightning strikes in the tower transmission, the ground
resistance of the tower must be kept to a low value of less than 5 Ω. This research is a study of
tower surge impedance using additional conductor line connected by parallel two overhead
ground wire at the top of the tower transmission line. The additional of ground wire which is
connected from the top of the tower utilizes copper and aluminium alloy for the simulation.
Calculation of tower surge impedance using finite element method by COMSOL in 3D
simulation based on traditional electromagnetism equations. Surge impedance values were
calculated, and it was found that the calculation results obtained with less than 0.5 % error
when using finite element method compare with conventional numerical method. Aluminium
alloy conductor was found to have an effect on reducing the overvoltage magnitude of
lightning strikes at the tower transmission line when compare with copper conductor. |
