Praktyki ochrony odgromowej napowietrznych linii średniego napięcia z przewodami niepełnoizolowanymi

The present paper aims to illustrate brief technical description of the selected problems of protection of medium-voltage overhead lines with covered conductors. Typical protection measures to be applied are describe and discussed with aim to determine critical points of lightning protection. Moreover special attention is paid for the economic and standardization issues introduction to the topic considered.
