Teridian公司71M65XX J＆D电子直流容错互感器的使用

摘要：耐直流电流互感器（CT）获得计量市场的重要性。通用的CT相比，他们有一个更大的相位角，并减少在低电流线性。本文讨论了如何从J＆D电子有限公司直流容错CTS可用于精确的电表， Teridian公司的单和多相电能计量SoC的优秀补偿功能相结合。这些SoC可以轻松地实现过电流和温度的CT输出的线性化。

Electronics
Introduction
DC-tolerant CTs are gaining importance in the metering marketplace. As compared to general-purpose CTs, DC-
tolerant CTs have a much larger phase angle and can also be less linear than general-purpose CTs at low cur-
rents. J&D Electronics Co Ltd, Korea, has introduced a series
