超高频气体绝缘变电站局部放电检测技术在过去10年左右的时间里，已经从实验室的好奇心发展成为对变电站即将发生的大多数故障进行早期预警的敏感手段。由于它是一种简单、灵敏和实用的技术，它被全世界的公用事业和开关设备制造商迅速接受。此外，公用事业公司发现有必要更加努力地推动他们的工厂，并需要确保其可靠性——即使他们可能有更少的员工来进行维护工作。作者描述了UHF技术现在如何被他们视为一种避免故障的经济有效手段，并提供当今客户所需的高质量供应。
The UHF technique of detecting partial discharges in gas insulated substations (GIS), has over the past 10 years or so been developed from a laboratory curiosity into a sensitive means of giving an early warning of most impending failures in the substation. Its rapid acceptance by both utilities and switchgear manufacturers worldwide has resulted from it being a simple, sensitive and practical technique. In addition, utilities are finding it necessary to drive their plant harder and need to be assured of its reliability-even though they may have fewer staff to carry out maintenance work. The author describes how the UHF technique is now seen by them as a cost effective means of avoiding failures, and providing the high quality of supply demanded by today's customers.
