Toote infoHeatTag analyzes suspended gases and particles inside the switchboard (14 gases measured, along with particles), applies a smart algorithm to sort internal cable issues from overheating, and sends an alarm via email or SMS.
HeatTag is neither a fire detector nor a smoke detector. It detects invisible yet hazardous transformations, of cable insulators, such as PVC, XLPE, EPR, typically between 170°C and 200°C.
Kasulikud omadusedCable connections can start to deteriorate due to improper tightening torque or constant vibrations over time. Deterioration can also occur because of damaged surfaces, due to corrosion, excessive pressure or friction.These conditions can be exaggerated by frequent temperature cycling. Fluctuations between cold nights and hot days, or low and high current, cause increased and decreased connection tightness. This, in turn, contributes to loosening.
In any of the conditions noted above, a critical sequence ofevents can begin: increasing electrical contact resistance induces a rise in temperature that accelerates the damage and the result is a thermal runaway that leads to overheating wire connections and/or overheating cables.
Above 200°C, the insulation material begins to change color. At approximately 300°C this transforms into cable smoke, melted insulation material or even fire. These conditions can be detected with a fire or smoke detector; however, at that point, the damage has already occurred in the electrical switchboard.
