This paper presents a newly developed, FPGA based, travelling wave fault recorder capable of simultaneously recording up to six input channels at 40 Mega samples per second (MSPS) at a 14 bit resolution. The fault recorder integrates a GPS receiver to provide accurate time tagging of recorded transients allowing both double-ended and single-ended schemes of fault location to be applied.
