Fig. 1 illustrates the experimental circuits, and Fig. 2 shows measured results. From the measured results, it becomes clear that a coaxial mode of surge propagation does not depend on the cable outer medium, either overhead or underground, as is well-known. However, an earth return mode is heavily dependent on the outer medium. EMTP simulations of the experiments are carried out, and the simulation results show a satisfactory accuracy in comparison with the experimental results. Surge characteristics of a cable system composed of submarine and underground / overhead cables are investigated based on EMTP simulation results considering cable cross-bonding and the length of a minor section. Table 1 summarizes the maximum overvoltage on phase of a 3-phase cable. It is clear from the table that the core overvoltage is not influenced by the outer medium of the cable. The cross-bonding reduces the core voltage by about 20%. Therefore it is better to adopt the crossbonding for the insulation of the cable core. On the contrary, the sheath overvoltage becomes much higher in a cross-bonded cable, especially if there is a submarine cable in the system. Thus the cross-bonding should not be used in a submarine part which costs a lot for re-installation.</style></abstract><issue><style face="normal" font="default" size="100%"></style></issue><work-type><style face="normal" font="default" size="100%"></style></work-type><accession-num><style face="normal" font="default" size="100%"></style></accession-num><call-num><style face="normal" font="default" size="100%"></style></call-num><notes><style face="normal" font="default" size="100%"></style></notes><custom1><style face="normal" font="default" size="100%"></style></custom1><custom2><style face="normal" font="default" size="100%"></style></custom2><custom3><style face="normal" font="default" size="100%"></style></custom3><custom4><style face="normal" font="default" size="100%"></style></custom4><custom5><style face="normal" font="default" size="100%"></style></custom5><custom6><style face="normal" font="default" size="100%"></style></custom6><custom7><style face="normal" font="default" size="100%"></style></custom7><research-notes><style face="normal" font="default" size="100%"></style></research-notes><num-vols><style face="normal" font="default" size="100%"></style></num-vols><orig-pub><style face="normal" font="default" size="100%"></style></orig-pub><reprint-edition><style face="normal" font="default" size="100%"></style></reprint-edition><section><style face="normal" font="default" size="100%"></style></section><auth-address><style face="normal" font="default" size="100%"></style></auth-address><remote-database-name><style face="normal" font="default" size="100%"></style></remote-database-name><remote-database-provider><style face="normal" font="default" size="100%"></style></remote-database-provider><label><style face="normal" font="default" size="100%"></style></label><access-date><style face="normal" font="default" size="100%"></style></access-date></record></records></xml>
