Power Quality Measurements from Controlled High-Impedance Fault Experiments

1.2 GB of power quality measurements recorded during laboratory experiments on high-impedance faults in medium-voltage covered conductors. The data includes RMS voltage and current, harmonics, phase angles, and power metrics, collected using a Hioki PQ3198 analyzer following IEC standards. Author Diogo Biasuz Dahlke published this dataset on figshare in May 2026.

Use Cases

• Developing fault detection models based on low-current fault signatures.
• Analyzing harmonic distortion patterns based on harmonic and interharmonic components.
• Studying the temporal evolution of fault events based on time-series measurements.
• Evaluating power quality metrics like power factor under varying experimental conditions.

Strengths

• Data was recorded using a Hioki PQ3198 Class A power quality analyzer, a professional-grade instrument.
• Measurements follow the IEC 61000-4-30 standards, ensuring a recognized methodology.
• Experiments were conducted under controlled conditions with variations in conductor configuration, surface material, and moisture states.
• The dataset is part of a broader multimodal collection, suggesting contextual richness.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect the bias inherent to controlled laboratory experiments rather than real-world field conditions.
