课程名称：单相和三相系统的电力计量 课程概述：该课程专注于电能表的研究，包括电力计、电能计、能量计或千瓦时表，这是一种用于测量住宅、企业或电动设备所消耗电能的设备。我们将研究电表的测量，包括在特定时间间隔内消耗的总电力。从电力公司的角度来看，探讨了为计费和监测目的而在客户场所安装的电表。课程中将开发典型的计费单位，最常见的是千瓦时（kWh），并学习如何在每个计费周期内读取这些数据。部分电表可能会测量需求，即在某个时间段内的最大用电量。“使用时间”计量允许在一天内变更电费，以记录高峰期的使用情况和低峰期的低费用情况。课程还涵盖了单相和三相计量测量。 学习成果：本课程的毕业生将熟悉以下内容： - 什么是电力 - 交流和直流电力 - 电压、电流及功率矢量（相量） - 电容性和电感性负载 - 有效功率、无效功率和表观功率（瓦特、无功伏安、视在功率） - 动功表 - 能量计 - 仪表变压器（电流和电压CT及PT） - 三线制单相计量 - 多相能量计 - 带有CT和PT的三线制单相计量 - 三相四线负载（"Y"连接）的计量 - 三相三线负载（Δ连接）的计量 - 计量测量标准 - 布朗德尔定理（相位与线路关系） 该课程为电力计量领域打下坚实基础，适合对电力系统有兴趣的学员。
This course concentrates on the electricity meter, electric meter, electrical meter, energy meter, or kilowatt-hour meter which is a device that measures the amount of electric energy consumed by a residence, a business, or an electrically powered device.Electric meter or energy meter measurements, the total power consumed over a time interval are examined.From the Electric utility perspective, electric meters installed at customers' premises for billing and monitoring purposes are examined. The typical calibrated in billing units are developed, the most common one being the kilowatt-hour (kWh) and how they are read once each billing period.If desired, some meters may measure demand, the maximum use of power in some interval. "Time of use" metering allows electric rates to be changed during a day, to record usage during peak high-cost periods and off-peak, lower-cost, periods. Single-phase and three-phase metering measurements are also covered.Learning Outcomes:Graduates of this course will be familiar with:What is Electric PowerAC & DC PowerVoltage Current, & Power Vectors (Phasors)Capacitive & Inductive LoadsReal Reactive & Apparent Power (Watts, Vars, VA)The Dynamometer WattmeterThe Energy MeterInstrument Transformers (Current & Voltage CT's & PT's)3-Wire, Single-Phase MeteringPolyphase Energy Meters3-Wire, Single-Phase Metering with CT's & PT'sMetering a 3 Phase 4 Wire Load ("Y" Connected)Metering a 3 Phase 3 Wire Load (Delta Connected)Metering Measurement StandardsBlondel's Theorem Phase & Line Relationship
