</p> <p> 誤差來(lái)源 </p> <p> （1）測(cè)量變換電路引入誤差：電能質(zhì)量分析儀工作時(shí)，電網(wǎng)中電壓、電流信號(hào)需分別經(jīng)過(guò)電壓互感器 </p> <p> (Potential Transformer，PT)、電流互感器(Current Transformer，CT)送入電能質(zhì)量分析儀，因此PT、CT的比例誤差和相角誤差直接影響到測(cè)量結(jié)果的準(zhǔn)確度。當(dāng)電能質(zhì)量分析儀工作在諧波條件下，PT、CT相角誤差發(fā)生改變，對(duì)各次諧波電壓、電流的轉(zhuǎn)換比例不一致，輸入ADC的被測(cè)信號(hào)發(fā)生變形，測(cè)量誤差增大。 </p> <p> （2）ADC量化誤差：ADC量化誤差指輸入信號(hào)進(jìn)行模數(shù)轉(zhuǎn)換時(shí)，用有限的數(shù)字信號(hào)來(lái)表示無(wú)限精度的模擬信號(hào)所造成的誤差。電能質(zhì)量分析儀常采用12位或16位的ADC，且ADC位數(shù)越大，其轉(zhuǎn)換精度越高，量化誤差越小，濟(jì)南高精度電力儀表，濟(jì)南高精度電力儀表。 </p> <p> （3）其他誤差：包括環(huán)境溫度、相對(duì)濕度等因素導(dǎo)致硬件電路產(chǎn)生的誤差，電子器件以及線路老化等因素致使測(cè)量結(jié)果產(chǎn)生的誤差。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:
