Abstract

Sequence time-domain reflectometry (STDR) and spread spectrum time-domain reflectometry (SSTDR) detect, locate, and diagnose faults in live (energized) electrical systems. In this paper, we survey the present SSTDR literature for discussions on theory, algorithms used in its analysis, and its more prominent implementations and applications. Our review includes both scientific litera-ture and selected patents. We also discuss future applications of SSTDR.

Keywords: electrical test and measurement; reflectometry; sequence time-domain reflectometry (STDR); spread spectrum time-domain reflectometry (SSTDR); time-domain reflectometry (TDR).
