This data-set consists of 3-phase differential currents of internal faults and 4 other transients cases for Phase Angle Regulators (PAR). The transients other than faults include magnetizing inrush, sympathetic inrush, external faults with CT saturation, and overexcitation conditions. PSCAD/EMTDC software is used for simulation of the internal faults and the transients.

Instructions: 

The files - ’fault_location_pha’, ’fault_location_phb’, and ’fault_location_phc’ have phase a,b,c differential currents for 46872 cases. Each row has 167 samples (one cycle). In fault_location_target’- the first 33480 are faults in series unit, next 13392 are faults in exciting unit. The files - ’transients_pha’, ’transients_phb’, and ’transients_phc’ have phase a,b,c differential currents for 13680 cases. Each row has 167 samples (one cycle). In fault_transient_target’- the first 720 - overexcitation, next 2520 - magnetizing inrush, next 2520 -sympathetic inrush, and next 7920 are external faults.

The dataset contains internal faults in power transformer and phase angle regulators (PAR) in a 5-bus interconnected system. It also has 6 other power system transients which include magnetising inrush, sympathetic inrush, external faults with CT saturation, capacitor switching, non-linear load switching, and ferroresonance. There are 88128 internal fault files and 12780 files of other transient disturbances. The faults and transients are simulated in PSCAD/EMTDC and the output files are in text format.

Instructions: 

Detailed description of all data files is provided in the *Dataset_Readme.pdf* file along with the dataset.
