Reproduction of a High Impedance Double line-to-ground Fault Using Real Oscillography Data

This paper presents the reproduction of an actual high impedance fault (HIF) event of type double line-to-ground using real oscillography data and ATP-EMTP software. The event occured in an overhead distribution system connected to substation Salinópolis 13.8 kV, after two cabes broke and touched a...

Description
Summary:This paper presents the reproduction of an actual high impedance fault (HIF) event of type double line-to-ground using real oscillography data and ATP-EMTP software. The event occured in an overhead distribution system connected to substation Salinópolis 13.8 kV, after two cabes broke and touched a soil contact surface. The reproduction method of the mentioned event is based on simple calculation of fault currents from neutral current measurements to generate the V × I curve used in the HIF model. The results show that current signals obtained from simulation match the current measurements, demonstrating the effectiveness of the proposed method.
