The distributed temperature sensing {DTS） is widely used in power cable monitoring system. In order to validate the conductor temperature calculation and dynamic cable rating calculation, we presented the verification tests. These tests were carried out by the different installation and different loading. During these tests~ the real conductor temperature of cable was determined by special thermocouple and compared with conductor temperature calculation of DTS. Power cables were installed in trenches, ducts, and tunnels, and the cycle-loading or step alternative current was through the cable. Results show that the verification test is available for characters evaluation of the DTS system. The verification test can validate the conductor temperature calculation of DTS and dynamic cable rating calculation. The verification test can also improve the calculate accuracy of DTS.
