SUMMARY OF LV AND MV CABLE TESTING METHODS - NEW TRENDS

Kabelska omrežja na SN nivoju prevzemajo vse večji delež oskrbe z električno energijo. Z njihovim razraščanjem se srečujemo z izzivi, kako zagotoviti njihovo obratovalno zanesljivost. Z željo, najti primerno diagnostično orodje, ki bi dalo dovolj informacij o stanju izolacije kablovoda sem predstavil nadzorovani zdržni preskus z napetostjo zelo nizke frekvence.Cable networks on the MV level take an increasing share of electricity supply. With their growth we are faced with the challenges how to ensure their operating reliability. In order to find suitable diagnostic tool that would give enough information about the state of the insulation of the cable system, i presented monitored withstand test with very low frequency voltage
