Electricity Dataset

Abstract: Measurements of electric power consumption in one household with a one-minute sampling rate over a period of almost 4 years. Different electrical quantities and some sub-metering values are available.

Data Set Information:
This archive contains 2075259 measurements gathered in a house located in Sceaux (7km of Paris, France) between December 2006 and November 2010 (47 months).
Notes:

(global_active_power*1000/60 - sub_metering_1 - sub_metering_2 - sub_metering_3) represents the active energy consumed every minute (in watt hour) in the household by electrical equipment not measured in sub-meterings 1, 2 and 3.
The dataset contains some missing values in the measurements (nearly 1,25% of the rows). All calendar timestamps are present in the dataset but for some timestamps, the measurement values are missing: a missing value is represented by the absence of value between two consecutive semi-colon attribute separators. For instance, the dataset shows missing values on April 28, 2007.

Attribute Information:

date: Date in format dd/mm/yyyy
time: time in format hh:mm:ss
global_active_power: household global minute-averaged active power (in kilowatt)
global_reactive_power: household global minute-averaged reactive power (in kilowatt)
voltage: minute-averaged voltage (in volt)
global_intensity: household global minute-averaged current intensity (in ampere)
sub_metering_1: energy sub-metering No. 1 (in watt-hour of active energy). It corresponds to the kitchen, containing mainly a dishwasher, an oven and a microwave (hot plates are not electric but gas powered).
sub_metering_2: energy sub-metering No. 2 (in watt-hour of active energy). It corresponds to the laundry room, containing a washing-machine, a tumble-drier, a refrigerator and a light.
sub_metering_3: energy sub-metering No. 3 (in watt-hour of active energy). It corresponds to an electric water-heater and an air-conditioner.

数据集信息：
本档案包含2075259个测量值，收集于法国斯克肖（距离巴黎7公里）的一所住宅，时间跨度为2006年12月至2010年11月（共计47个月）。

注释：
(global_active_power*1000/60 - sub_metering_1 - sub_metering_2 - sub_metering_3) 表示家庭内未在分表计量1、2和3中测量的电气设备每分钟消耗的活性能量（以瓦时计）。
该数据集包含部分缺失值（约1.25%的行）。所有日历时间戳均包含在数据集中，但对于某些时间戳，测量值缺失：缺失值以两个连续的分号属性分隔符之间的值不存在表示。例如，数据集显示2007年4月28日存在缺失值。

属性信息：
date：日期格式为dd/mm/yyyy
time：时间格式为hh:mm:ss
global_active_power：家庭全局每分钟平均有功功率（以千瓦计）
global_reactive_power：家庭全局每分钟平均无功功率（以千瓦计）
voltage：每分钟平均电压（以伏特计）
global_intensity：家庭全局每分钟平均电流强度（以安培计）
sub_metering_1：能源分表计量1（以有功能量瓦时计）。它对应厨房，主要包含洗碗机、烤箱和微波炉（燃气灶具非电气加热）。
sub_metering_2：能源分表计量2（以有功能量瓦时计）。它对应洗衣房，包含洗衣机、烘干机、冰箱和照明设备。
sub_metering_3：能源分表计量3（以有功能量瓦时计）。它对应电热水器空调设备。
