Nowadays in the Czech Republic begins implementation of new types of leadership that use the system with insulated conductors nowadays. This system is used because of the use of conductors in difficulteis to reach terrains and lower failure rate. The finding of specific faults is problem, because today's digital protection are not able to find it.

Opis:: The paper dealt with the issue of breakdowns detection of isolated hanging wires on the medium-voltage transmission. The main aim of article is to describe the function of created breakdowns detector and evaluation its. The breakdowns detector is created based in indicators of faults such as touch between tree limbs and insulated wire, touch tree limbs with several phases or fall insulated wire on the ground. Breakdowns detector has been created because today digital protection was not able to detect the aforementioned faults (e.g. a fault between ground and insulated wire is not a complete ground fault).Therefore, the measured data in the fault-free situation will be compared with the simulated measured faults data in the 22 kV insulated wire type of SAX-W.
This paper has been elaborated in the framework of the project Opportunity for young researchers, reg. no. CZ.1.07/2.3.00/30.0016, supported by Operational Pro-gramme Education for Competitiveness and co-financed by the European Social Fund and the state budget of the Czech Republic and project MSMT KONTAKT II: LH11125 - Investigation of the ground current fields around the electrified lines.
