In the field of high voltage live line maintenance RTE can rely on many methods for ordinary operations like replacing insulators, line hardware, or repairing damaged conductors. Nevertheless heavier maintenance is sometimes needed such as tower replacement. Therefore RTE has developed a new piece of equipment able to temporarily support the line while the tower is removed. This tool consists of a...
Whether in as much as the electric field is concerned it has been settled by the international scientific community since the 90's that there are no direct biological effects, only physiological effects caused by densities of the currents higher than 10 mA/sqm induced into the human body. When considering the impact of the magnetic component of the electromagnetic field of industrial frequency, the...
The first inquiry for new tower designs was launched by Elia (the Belgian TSO) in 2008 in the frame of the need for new 380 kV transmission lines. The requirements of this inquiry included minimum visual effects (similar to the existing 150 kV tower silhouette), low EMF and AN levels under the line and a maximum transport capacity of 3 GVA/circuit. Based on these requirements the innovative compact...
Hungary was one of the pioneers of high voltage live-line maintenance in the 1960s. Many of the currently applied technologies and equipment is related to the developments of Dr. Béla Csikós, one of the pioneers of this technology. Nowadays different working methods are used worldwide for the maintenance of the energized components of the high voltage grid. As a part of an international project, Budapest...
