House 02 in ENERTALK dataset

Zip files enertalk-dataset-{house_number} contain a directory for each houses. Each directory holds a set of subdirectories that contain Parquet files for the daily aggregate and appliance-level data. The naming convention for these subdirectories is “” (e.g. “20161124” for November 24, 2016). The Parquet files are named “\_.parquet.gzip” (e.g. “01\_fridge.parquet.gzip”). In these names, the two-digit integer is uniquely associated with a distinct measuring device in a house. Each Parquet file consists of three columns: “timestamp,” “active\_power,” and “reactive\_power.” The “timestamp” column contains Unix timestamps in milliseconds, such that 1000 corresponds to one second. The “active\_power” column represents active power in watts and the “reactive\_power” column represents reactive power in VAR (volt-ampere reactive) units.

名为`enertalk-dataset-{house_number}`的压缩归档文件包含与各住宅一一对应的目录。每个住宅目录下包含若干子目录，用于存储每日聚合用电数据及电器级用电数据的Parquet文件。这些子目录的命名规则为日期字符串（例如"20161124"代表2016年11月24日）。Parquet文件的命名格式为「[两位设备编号]_[设备名称].parquet.gzip」（例如"01_fridge.parquet.gzip"）。在该命名规则中，两位整数唯一对应住宅内的一台独立测量设备。每个Parquet文件包含三列数据：时间戳（timestamp）、有功功率（active_power）以及无功功率（reactive_power）。时间戳列存储毫秒级Unix时间戳，其中1000对应1秒。有功功率列以瓦特（W）为单位表征有功功率，无功功率列则以VAR（无功伏安，volt-ampere reactive）为单位表征无功功率。
