House 18 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.以`enertalk-dataset-{house_number}`命名的压缩包内含对应每户住宅的目录。每个目录下包含若干子目录，这些子目录存储了每日聚合用电数据与单设备级用电数据的Parquet文件（Parquet）。子目录的命名约定为日期字符串格式，例如2016年11月24日对应的目录名为"20161124"。此类Parquet文件的命名格式为"[两位数设备编号]_[设备名称].parquet.gzip"，举例如"01_fridge.parquet.gzip"。文件名中的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："timestamp"、"active_power"与"reactive_power"。其中"timestamp"列存储毫秒级Unix时间戳（Unix timestamp），即数值1000对应1秒；"active_power"列以瓦特（W）为单位表示有功功率；"reactive_power"列以VAR（volt-ampere reactive，无功伏安）为单位表示无功功率。
