HIGH VOLTAGE AC/DC OR DC/AC CONVERTER STATION WITH FIBEROPTIC CURRENT SENSOR |
摘要 |
DC current in a high voltage AC/DC or DC/AC converter station can be measured via the Faraday effect in one or more loops of an optical sensing fiber located at the base of a bushing extending through a wall of the hall. This arrangement can exploit the base of the bushing being at ground potential, which can simplify mounting work and maintenance. |
