电能表怎么看和读，有什么原理?

Release date： View count：531

　　电能表是用来测量电能的仪表，又称电度表，火表，千瓦小时表，指测量各种电学量的仪表。电力的发明造福了千家万户。每家每户都需要使用电。电能表进行测量，之后才能由电力公司进行收费。电能表由供电部门安装，设置显示和计费程序参数，自动上传数据或由收费部门读数抄表，用户不可以去操作。下面小编来介绍一下电能表怎么看和读，有什么原理?

　　一.电能表怎么看和读?

　　电表一般循环显示多种数据，用户如需知道用了多少度电，可在其循环显示中读取《当前组合有功总电量》和《上月组合有功总电量》两项读数，两数之差即为本月用了多少度电。这里显示的是8位数字，前6位是整数位，后两位是小数位。单位是kwh，即电度数。
