Helicopter installation of Transmission Line Conductor Monitor
Installation of transmission line conductor monitors have been tricky affairs in the past, usually requiring a line outage and in some cases even a modification of a dead-end tower’s insulator-string/hardware-assembly. The Lindsey TLM conductor monitor requires no line outage or line modification. It has been widely installed via both hot stick and bare hand live line methods. The sensor’s design and resulting simplicity of installation also allow for fast installation by helicopter.
At the recent IEEE ESMO show, held in September, 2016 in Columbus, OH, a Lindsey TLM conductor monitor was installed on a live 230kV line via helicopter. Total time of installation from when the bond wire connection was made, to when it was removed, was 34 seconds. THAT is an easy to install conductor monitor! Watch the installation on T&D World magazine’s website.
Once installed, the TLM conductor monitor provides continuous clearance measurement of the conductor to ground, line current, conductor temperature, ground temperature, and conductor vibration. Everything about the TLM monitor is self-contained from integral line current power-harvesting power supply, to built-in communications. This means the 34 second install time is all that it needed to start receiving data.
The Lindsey TLM conductor monitor can be used for stand-alone conductor clearance monitoring, monitoring line crossings, monitoring conductor behavior, and as the primary data feed for dynamic line rating systems such as Lindsey’s SMARTLINE system.
