چکیده

A wave propagation characteristic is very significant to investigate a transient voltage and insulation design of a cable. This paper carries out an experiment and a simulation of wave propagation characteristics on an insulation covered conductor in comparison with a bare conductor. The simulations are carried out using Electro Magnetic Transient Program (EMTP) and Finite Difference Time Domain (FDTD) method. The measured results and simulated results are compared for bare and covered conductors. It has been found that in the case of the covered conductor, the characteristics impedance in the simulation result is less by few percent from that of the bare conductor. The EMTP and FDTD simulations reasonably agree with the measured and theoretical results when the cell size and its number in the FDTD are appropriate.
