  1. Dds951 series electronic single - phase electric meter is the most advanced static electronic meter in china. the meter designs use large - scale intergated circuit. high reliability step motor, it can the ac single - phase active energv voltage rating : 220v : frequency 50hz, positive and negative two directions and accumulates in one direction. the test singnal is isolated by phototransistor : it also has the function of anti - fraud, and indicates it s operation situation on flash light, so it could be managed very easy

    Dds951單相電子電能表,是金雀儀表公司開發的新型電度表。該產品是採用規模專用集成電路,高可靠性步進電機等先進技術製造的國內最新電能試題新產品,用來計量額定電壓為220v ,頻率為50hz的交流單相有功電能,該產品能夠精確計量正負兩方向的有功電能,且以同一個方向累計。
  2. Compared with the induction meter, the electronic meter ' s measurement error is affected diminutively by the change of the frequency, that is to say, the electronic meter has a wide frequency respond characteristic and its error - frequency characteristic curve is flat. therefore, taking the whole energy as measurement standard, the measurement error of electronic meter is less than that of induction meter very much ; while the measurement error of electronic meter is bigger than that of induction meter when taking the basic energy as measurement standard

    和感應式電能表相比,電子式電能表的計量誤差受頻率變化影響較小,具有較寬的頻率響應,誤差頻率特性曲線較為平坦,因此,在諧波存在下以全能量為計量標準時,電子式電能表的計量誤差遠遠小於感應式電能表的電能計量誤差,而以基波能量為計量標準時,電子式電能表的計量誤差比感應式電能表的計量誤差大。
