Low-frequency electrical measurements from laboratory jaw crushing tests of granite

This dataset contains low-frequency electrical measurements recorded during laboratory jaw crushing tests of granite. The original data were exported from a Fluke power quality analyser/recorder as CSV files. Each source file corresponds to one experimental sample and contains multiple electrical channels recorded as time series, including current, voltage, active power, reactive power, apparent power and power factor. The dataset includes unchanged raw Fluke CSV exports, processed wide- and long-format tables, descriptive statistics, channel-level metadata, file-level metadata, a data dictionary and a validation summary. The sample identifiers correspond to the experimental samples used in the laboratory crushing tests.
