Abstract :
A telecommunication subscriber cable is a bundle of twisted-pair wires terminated with gas discharge tube arresters. The lightning-induced voltages on multiple twisted-pair wires over a lossy ground are calculated by an equivalent single-wire line representation. The simplified single-wire line representation shows a good agreement with the result of the twisted pairs of wires. Additionally, the transient response of a gas discharge tube arrester is also simulated by the finite-difference time-domain (FDTD) method
