The verification test method on DTS system for power cable conductor-temperature calculation accuracy is described in this paper. The DTS temperature measure accuracy and positional accuracy are tests firstly. During the test a power cable laying in tunnel and applying different load currents ,the conductor-temperature measured value and the DTS system calculated value were compared. Testing process are employs the T-type thermocouple for conductor-temperature measure. DTS system calculates the conductor-temperature according to load current, over-sheath temperature etc. The difference between measured and calculated value were analyzed and compared, that was used for verify the accuracy of the power cable conductor temperature calculated by the DTS system.
