Experimental analysis of electrical values during earth faults
The MV compensated Networks in Czech Republic are operated as nonsymmetrical, that means as networks with non-transposed lines. The paper deals with experiments which were realized in distribution network held by E.ON Czech Republic. There were made a few different faults (low-impedance, spark gap arc, damaged MV cable, 1.6 kΩ, 4 kΩ and unearthed console of concrete tower) for three different places, for tuned and untuned Petersen coil and for some types of faults for all phases too, that means forty eight experimental faults. During each experiment the shunting of affected phase was applied.
