Underground Cable Temperature Sensors for Transit Systems

April 06, 2017 by Jeff Shepard

Torino Power Solutions Inc. has begun developing a new underground temperature sensor that will focus on underground cable failures that plague most of the world's largest subway systems. Torino has been in recent discussions with some of the largest public transportation agencies in North America. Torino is the maker of Powerline Monitoring (PLM) system sensors for utility transmission lines.

The Company is reviewing ways to adapt its unique hollow sensor technology to deliver real-time underground temperature data to major transit operators to help detect and avoid underground cable failures before they turn into costly outages and delays for the public.

Underground transmission and distribution circuits are being continually overextended and in many cases cause overheating. Operators are in need of real-time, accurate information as to the maximum loads that may safely be impressed on underground cables without exceeding the temperature limits of such cables.

Rav Mlait, CEO of Torino, commented, "We are delighted to have a chance to develop a custom sensor to monitor the temperature of the underground cables in real-time before costly failures occur. Underground cable failure is a significant market opportunity in search of a solution. Torino, with its durable industrial sensor technology, is increasingly being called upon to provide custom solutions to major technical challenges such as this, as well as provide vital data for broader IIOT strategies.”

The Torino PLM system is an instrumentation platform designed for Dynamic Line Ratings (DLR), data acquisition, data logging, and alarm monitoring applications on high voltage, overhead conductor systems. The Torino PLM system consists of Microwave Cavity sensors (MC Sensors) applied to the conductor and an interrogator (communications panel) attached to the power pole or tower.

“The Torino PLM system is unique because of our completely passive (no electronics, no wires, no batteries) MC Sensors that provide utilities with the most durable, easy to install, maintenance free sensor system. The Torino PLM system provides asset managers with real-time, temperature monitoring of the conductor. Furthermore, it measures 3-phase line temperature and is ideal for transmission and distribution lines,” Mlait concluded.
