数字量输出型直流电压互感器的误差特性分析
Error characteristic analysis of digital output type DC voltage transformer
摘要
Abstract
In view of the lack of research on the actual error condition and error characteristics of the digital output type DC voltage transformer,an error analysis model of the digital output type DC voltage transformer was established. The field cali-bration test was completed,the actual error condition was obtained,and the error characteristics were analyzed in detail. The re-sults show that:There exists the phenomenon of over tolerance in the digital output type DC voltage transformer,but it can meet the 0.2 level requirements by means of error correction;The linearity of basic errors is about 0.1% to 0.2%;Both the rise and fall variation and the short time stability are 10-4orders of magnitude;The phenomenon of zero drift exists,and the zero correc-tion improves the linearity by 0.08%,as well as enhances the measurement accuracy by 0.1% at 10% rated voltage.关键词
