Add to ORKGOn-line monitoring has proven to be an effective technology to detect deteriorating high voltage bushings and prevent failures. While there is much focus placed on the monitor and the data it provides, the sensors used to transmit the signals are often overlooked. An on-line bushing monitoring program is only as good as the quality and reliability of the sensors used to provide the signals. Many problems and false alarms can be avoided by using a properly designed sensor and making sure it is correctly installed. This article will discuss what to consider when selecting a bushing sensor and how to install the sensor properly
