In a previous article, the authors described the development of single-phase protective shorting devices (SPSDs) and the merits of using them aboard ship and in relay devices. In this article, they note that relay SPSDs exhibit certain shortcomings, however. For example, after a single-phase short in a network has been eliminated, the relay devices cannot independently return to their original position, but require manual clearing. They also exhibit comparatively slow response speed and low sensitivity. An improved high-speed thyrister SPSD that the authors have developed is then described. It is sensitive to an incomplete single-phase short through a resistor of 1 kOhm or less. Used in nets, the devices automatically return to their original position.
