ABSTRACT:
Apparatus and method for real-time analysis of an electric power transmission link status direct buried or installed in a duct or a tunnel are described. The method includes: real-time measuring a surface distributed temperature of the link by using a distributed temperature sensor installed along a longitudinal direction of the link; calculating a conductor temperature of the link on the basis of the surface distributed temperature and an electric current flowing through the link; calculating a heat flow emitted out of the link on the basis of the surface distributed temperature and the conductor temperature; and real-time calculating a thermal parameter of an environment around the link on the basis of the heat flow. Thus, it is possible to calculate operating conditions of the link more accurately and improve safety of electric power transmission by real-time calculating the thermal parameter of the environment around the link.
