Abstract

Elastic sleeve (1) for electrically insulating a HV/MV power conductor in a power network, comprising a) a shrinkable or expandable elastic sleeve body (10); b) a receiving space (20) in the sleeve body, for receiving the power conductor; c) a cavity (30) formed in the sleeve body; and d) a divider assembly (40), arranged, at least partially, in the cavity and comprising a plurality of discrete impedance elements, operable as a voltage divider for sensing a voltage of an inner conductor of the power conductor.
