| 电表计量精度选择 Selection of Metering Accuracy of Electric Meter 我们常见的精度有0.2S、0.5、0.5S、1.0、2.0。，数值越小的话，精度越高，单相电表最高只能做到1级的精度，三相电表最高可以做到0.1s级，但是一般都以0.5s和0.2s为主，1.0级的电表允许误差在±1%以内。 Our common accuracy is 0.2S, 0.5, 0.5S, 1.0, 2.0. The smaller the numerical value, the higher the accuracy, the single-phase meter can only achieve the highest level of accuracy, the three-phase meter can achieve the highest level of 0.1s, but generally 0.5s and 0.2S are the main, the allowable error of 1.0 level meters is less than (+1%). 每用100度电，最多只允许多计量或少计量1度，现实中有可能是有的用户多计了，有的少计了。但实际上电表厂为了检验合格，误差控制得更严，均在0.6%以内，即要用1000度电才会产生最多6度电的差异。 For every 100 kilowatt-hour electricity, only one degree more or less is allowed. In reality, there may be more users and less users. But in fact, in order to pass the test, the error control is more stringent, which is less than 0.6%. That is to say, the difference of up to 6 degrees of electricity can only be produced by using 1000 degrees of electricity. |
