Minute-wise voltage data collected in Electricity Supply Monitoring Initiative

About the Electricity Supply Monitoring Initiative Electricity Supply Monitoring Initiative (ESMI) is a program being implemented by Prayas (Energy Group), a non-governmental, non-profit organisation based in Pune, India. The initiative aims to improve transparency and provide evidence based feedback about the quality of electricity supply. Under ESMI, specially designed, mobile data enabled monitors have been deployed at each location and supply quality data is published daily on watchyourpower.org. ESMI was selected as a finalist for Google Impact Challenge, India, 2013, given to NGOs using technology for social impact. It was launched in March 2015 and currently covers over 60 districts across India. How the data is collected The electricity supply monitor is an electronic device as small as a handheld radio. The device is designed to work as a plug and play unit and starts working as soon as it is plugged into a plug point. The device measures and records voltage with an accuracy of +/- 4 V, across a live electricity supply line for every minute and transmits the same over GPRS network to a central server. About the data The data uploaded in the dataverse has been collected from ESMI installations in India over the years, since 2014. The data is location-wise, minute-wise voltage data. All possible care and efforts have been undertaken, to verify the interruptions from our side, however the data has been made available on ‘as is where is’ basis. In case of queries, kindly write to us on [e-mail]. A few pointers to consider before using the data • The time period for the data is from November 2014 to December 2018 (would be updated from time to time) • The data for a location may not be continuous across the years • A ‘0’ voltage reading means a power outage • Missing data should be interpreted as unavailable data and not as interruption • Certain locations have been marked as [Offline], which indicates that the monitoring at the locations has been discontinued Structure of files The location information file has columns as follows Location name - Name of the location where the data was collected From date - Data is available from this date To date - Data is available till this date District - District where the location is situated State - State where the location is situated Category - Whether the location is rural, town, or a mega city Connection type - Domestic/Non-domestic/Agricultural connection The data files have columns as follows Location name - Name of the location where the data was collected Date - Date for the voltage recording Hour - Hour of the day (0 to 23) Min 0 - Voltage for the 0th minute of the hour Min 1 - Voltage for the 1st minute of the hour ... Min 59 - Voltage for the 59th minute of the hour Terms of use The information made available on the website and through ESMI is made available on ‘as is where is’ basis. Though reasonable care is taken to provide reliable data, neither Prayas, nor any of its agents, contractors, employees can be held responsible for use of any data or information made available herein. Anybody is welcome to make full use of the information available herein for any non-commercial, academic and research purpose, provided source of the information is clearly acknowledged. We will highly appreciate if we are intimated of use of this data and a copy of the publication, paper or report using this data is shared with us at [e-mail]

关于电力供应监测倡议（Electricity Supply Monitoring Initiative, ESMI）
该倡议由印度浦那的非政府非营利组织普拉亚斯能源集团（Prayas (Energy Group)）实施，旨在提升电力供应质量相关信息的透明度，并提供基于实证的反馈。在ESMI框架下，项目方已在各监测点位部署特制的移动数据采集终端，电力供应质量数据每日会发布至watchyourpower.org平台。ESMI曾入选2013年谷歌印度影响力挑战赛（Google Impact Challenge, India）决赛，该奖项旨在表彰利用技术实现社会影响力的非政府组织。该倡议于2015年3月启动，目前已覆盖印度超过60个县。

数据采集方式
该电力监测终端体积小巧，类似手持收音机，设计为即插即用设备，插入电源插座即可启动运行。设备可对供电线路的电压进行每分钟一次的测量与记录，测量精度为±4V，并通过GPRS网络将数据传输至中央服务器。

关于数据集
本数据集收录的内容为2014年以来印度境内各ESMI监测点位多年来的采集数据。数据为按点位、按分钟粒度划分的电压数据。项目方已尽最大努力对数据中断情况进行核验，但本数据集仍按「现状提供」原则予以公开。若有疑问，请发送邮件至[e-mail]与我们联系。

使用数据集前须知
1. 数据时间范围为2014年11月至2018年12月（后续将不定期更新）
2. 单个点位的年度数据可能存在不连续性
3. 电压读数为0代表发生停电
4. 缺失数据应视为不可用数据，而非供电中断
5. 部分点位被标记为「离线」，表示该点位的监测工作已终止

文件结构
点位信息文件包含以下字段：
- 点位名称：采集数据的点位名称
- 起始日期：该点位数据的可获取起始时间
- 终止日期：该点位数据的可获取截止时间
- 所属县：点位所在的县
- 所属邦/州：点位所在的邦/州
- 点位类别：点位类型，包括农村、城镇或特大城市
- 用电类型：用电分类，包括居民用电、非居民用电或农业用电

数据文件包含以下字段：
- 点位名称：采集数据的点位名称
- 日期：电压记录的日期
- 小时：当日时段（0至23时）
- Min 0：该小时第0分钟的电压读数
- Min 1：该小时第1分钟的电压读数
……
- Min 59：该小时第59分钟的电压读数

使用条款
本网站及ESMI项目公开的信息均按「现状提供」原则发布。尽管项目方已采取合理措施保障数据可靠性，但普拉亚斯能源集团及其关联方、承包商、雇员均不对因使用本数据集所涉及的任何数据或信息承担责任。
任何人可出于非商业、学术或研究目的自由使用本数据集所公开的信息，但需明确标注信息来源。若您使用本数据集进行相关创作，请及时告知我们，并将使用本数据的出版物、论文或报告副本发送至[e-mail]，我们将不胜感激。
