The cable trays are located in the underground electrical cable galleries.  Due to line-of-sight issues of traditional thermography services, it is difficult to achieve a full survey that covers inaccessible tunnel areas containing power cables. For this reason, the client selected AP Sensing’s LHD solution. Our system completely and continuously monitors the cable trays of all MV electrical power cables with automatically-generated alarms to instantly alert facility managers and provide the location of a potential fire or hotspot for further action.
