Distance protection has several protected zones based on transmission line impedance measurements, typically zone1 as main protection, zone2 and zone3 as remote backup protection. northern lights cycle peakWebb1 apr. 2024 · The accelerated operation of distance relay is an important issue to improve the power system stability. The zone-1 of distance relay usually covers about 80% of the transmission line length with an instantaneous operation, while during resistive faults the coverage of zone-1 may be reduced considerably. how to rotate huion tabletWebbDistance protection is a mature protection mainly used in transmission systems . It is based on the observation that the protected line impedance is proportional to its length: monitoring changes in the impedance (e.g. by measuring locally voltage and current) thus enables the identification of a fault without any communication device. how to rotate image horizontally in photoshopWebbThe proposed protection method was applied to the common neutral multi-ground distribution system to validate the protection against single- line-ground fault through the PSCAD/EMTDC software package and effectively detect and isolate only the zone of single-line- ground fault without malfunctions.
