N2 - This paper is concerned with the development of a fast computational methodology for dynamical estimation of the temperature in transmission cables solely based on current measurements and an enhanced version of the lumped parameters model, also denoted thermo electric equivalents (TEE). It is found that the calculated temperature estimations are fairly accurate — within 1.5<sup>o</sup>C of the finite element method (FEM) simulation to which it is compared — both when looking at the temperature profile (time dependent) and the temperature distribution (geometric dependent). The methodology moreover enables real time emergency ratings, such that the transmission system operator can make well-founded decisions during faults. Hereunder is included the capability of producing high resolution loadability vs. time schedules within few minutes, such that the TSO can safely control the system.
