Abstract :
This paper was written after some tests for default detection in MV network with compensated neutral in Romania. The results after these experiments are presented in comparison with numerical simulation. The results of this research are put into practice through a hardware device BZCD - 2 as digital protection block. The experimental determination has demonstrated very good reaction of this protection.
