抄録

The applicability of an optical fiber sensor to the monitoring of SF6 gas condition in gas insulated equipments in power transmission line was investigated. Two different designs of an optical fiber sensor were suggested and tested. The float type sensor was shown to be appropriate for a sudden pressure relay, whereas the diaphragm type sensor was applicable to a sudden pressure relay as well as a gas detection relay. Both sensors exhibited almost linear responses with pressure changes. Unlike the existing sudden pressure relays and gas detection relays, fiber sensors generate analog output signals which improve monitoring capability of the system. Non-contact and noise immune natures of the fiber sensors increase system reliability.
