Following the implementation of the antigalloping devices for the 400 kV o/h lines with 2 subconductors per phase, as explained in our paper presented by the occasion of the ICOLIM 2014 in Budapest, a new antigalloping device of the same torsional damper and detuner pendulum type was created and already implemented on some of the 400 kV with 3 subconductors per phase in Romania, in 2015. The device...
The concept of the damping pendulum as torsional damper and detuner (TDD) was created and reported in 1993 by its authors led by Prof. Jean-Louis Lilien from University of Liege-Belgium. Several versions were designed, tested and even used in some minor projects, demonstrating their high capacity to solve the risk of the overhead line conductor galloping with usual frequencies in the range 0.4–0.6...
The increased accuracy into the fault's detection and location make an easier task for maintenance, this being the reason to develop new possibilities to a precise estimation of the fault location. The paper presents the results of the implementation of two fault location algorithms in ATP-EMTP program. Some ATP-MODELS modules were associated to the ATP model of different transmission grids, these...
