PLAID 2014: High-Frequency Electrical Measurements from Household Appliances

The 2014 version of the Plug-Load Appliance Identification Dataset (PLAID) contains voltage and current measurements from different electrical household appliances. Data was sampled at 30 kHz and collected at 65 different locations in Pittsburgh, Pennsylvania (US). The dataset was authored by Jingkun Gao and is available under an Open Access license.

Use Cases

• Appliance identification and classification based on high-frequency voltage and current signatures.
• Developing energy disaggregation models for smart home applications.
• Analyzing the electrical load profiles of common household devices.
• Benchmarking signal processing techniques for time-series data sampled at 30 kHz.

Strengths

• Measurements are sampled at a high frequency of 30 kHz, capturing detailed electrical waveforms.
• Data was collected from 65 distinct locations, suggesting potential geographic diversity within Pittsburgh.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
