Sažetak
In this paper, the analysis of digital protection relays setting in a MV transformer station grounded via a low-ohmic resistor is presented. Theoretical background on low-ohmic resistor grounding in a transformer station is provided. EasyPower PowerProtector software is used for simulation and relay settings. Protective relay coordination after the simulation of a 3-phase fault and a line-to-ground fault on different selected buses in transformer station 35/10 kV is performed. Digital ABB relays series REF 541 were used for low-ohmic resistor thermal, short-circuit and overcurrent protection and overload protection of the low voltage transformer side. The results of analysis indicate correct selectivity of overcurrent protection devices in all cases
