The industry's first self-protected, light-triggered thyristor was developed, fabricated and field-demonstrated as part of a recently completed research project sponsored by EPRI; it is installed on a 13.8-kV, 40-MVAR ac switch using 16 series-connected devices operating in one phase of a static var compensator at the Minnesota Power Co.'s Shanon Substation. The light-triggered thyristor was designed with internal overvoltage protection (safe turn-on at a preset overvoltage level) and with significantly improved dv/de withstand characteristics. In the process, the ac switch in the static var compensator was redesigned to incorporate 16 instead of the originally-installed 24 series-connected thyristors. This paper describes the technology as well as the demonstration and performance of the new device.
