ElectronicsSurge ArrestersTransmission Line ArresterKey Features HV arrester suspended from a transmission line givingenhanced transmission line performance. Increasing system line voltage on standard insulatedtransmission lines.Benefits of TLA ApplicationsCat son.com.auSurge Arresters Minimising circuit breaker operation with possiblesystem outage resulting from back flashover on thetransmission line. Switching overvoltages are absorbed over the length ofthe line reducing the severity of surge at the substation. Transmission systems can be operated even wheresub-soil gives poor tower footing resistance. Eliminating interrupted power supply for sensitiveindustrial processes. Installing Transmission Line Arresters on a standard 3phase voltage system along the line, at calculatedintervals, allows for optimum performance of the TLA,to give an increased system line voltage. Therefore eliminating the need to increase the standardinsulation level required on conventional systemupgrade.15-13
