House 19 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}`的压缩包中，每一户家庭均对应一个专属目录。每个目录下设有若干子目录，这些子目录内存储了用于日汇总用电数据与设备级用电数据的Parquet（Parquet）文件。子目录的命名格式为YYYYMMDD形式，例如「20161124」代表2016年11月24日。Parquet文件的命名格式为「[两位整数]_[设备标识].parquet.gzip」，例如「01_fridge.parquet.gzip」。文件名中的两位整数，唯一对应一户家庭内的一台独立计量设备。每个Parquet文件均包含三列数据：「timestamp（时间戳）」、「active_power（有功功率）」与「reactive_power（无功功率）」。其中「timestamp」列存储单位为毫秒的Unix时间戳，即数值1000对应1秒；「active_power」列代表以瓦特（W）为单位的有功功率；「reactive_power」列代表以VAR（volt-ampere reactive，无功伏安）为单位的无功功率。
