Identification of High-resistance Earth Faults in Medium Voltage Networks Using Higher Harmonics
Journal Title: Acta Energetica - Year 2017, Vol 30, Issue 1
Abstract
One way to detect line-to-earth arc faults and high-resistance faults in compensated medium voltage networks is based on the criterion of reactive power of higher harmonics in zero sequence voltage and current components. The harmonic content of currents and voltages was evaluated as a function of non-linear short-circuits resistance parameters. This criterion-based earth fault protection’s model is described. Examples of high-resistance fault detection are attached.
