Abstract

The technique of the electric field distribution analysis in the 330 kV outdoor switch-gear is proposed. There are the zones in which electric field strength is greater than maximum permissible values by European Directive 2004/40/EU. The peak values of electric field strength are under the wires of A and C phases. These results are confirmed using programme package COMSOL. The electric field strength can be diminished to permissible values by shielding. It can be used as a shield comprised of some metal bars mounted parallel to wires of A and C phases over the shielding place. For the purpose of shielding it is sufficient to mount two bars provided they are mounted in the height of at least 2,4 m. Ill. 5, bibl. 4, tabl. 1 (in English; abstracts in English and Lithuanian).
