Swiss Temperature Measuring Optical Cable Technology
Distributed temperature sensing systems (DTS) are devices which measure temperatures by means of functioning as linear. Temperatures are recorded along the optical sensor cable, thus not at points, but as a continuous profile. A high accuracy of temperature determination is achieved over great distances. Typically the DTS systems can locate the temperature to a spatial resolution of 1 m with accuracy to within ±1 °C at a resolution of 0.01 °C. Measurement distan.

Maximum temperature of the third-level distribution box
The maximum temperature is 140 o C for copper busbars, 125 o C for individual components (in accordance with the component manufacturer's instructions), and 105 o C for external insulated conductors. The iec standard for temperature rise test is one of the most important compliance requirements in electrical engineering, especially for switchgear, transformers, busbars, control panels, and industrial equipment. Temperature rise directly affects insulation life, operational safety, reliability. Suppose the room ambient temperature is 35 o C, (reference temperature of the IEC 61439). By the way, 35 o C is about the average. The IEC 61439 series of standards deals with requirements for low-voltage switchgear assemblies and includes all the colloquial “distribution cabinets” from a domestic installation or industrial low-voltage main distribution systems to switching points in the public low-voltage grid. Terminations for standard rated breakers: UL 489 Paragraph 7. Higher temperatures can impact equipment reliability. Ga Porcelain Cutouts in 160 KVA / 315 KVA box to protect outgoing circuits.
