ANALYSIS OF FAULT CONDITION CAUSED BY PHASE INTERRUPTION OF HV OVERHEAD LINE

The paper deals with the issue of single-phase interruption in HV distribution grid due to conductor rupture. Based on the real fault that occurred in the Czech distribution grid, a mathematical model was built to perform simulations and analysis of results were conducted. The main objective is to give recommendations to DSO how to identify this type of fault and reveal the risks of this fault for the grid operation.
