On-line monitoring of OHL conductor temperature; live-line installation

This paper shows the Live working technology to install the On-line Monitoring system on Overhead lines. The Monitoring System, which is based on the contact-free SAW-technique, is introduced. During periods of high ambient temperatures, low wind speed and high electrical system load conditions, monitoring and analyzing regional areas of the transmission network can be essential to evaluate the conductor operating temperature. The temperature of the conductor at the point of installation can be measured and the data transmitted wirelessly to a data collection point.
