• RE: AD7124-4 for two 3 wire RTDs

    Not sure why it was appeared recently. But to update an answer on this post. The last comment referred to 3-wire configuration wherein the reference is at high side. So this might require reference resistor for each RTD. However, to save cost the user…

  • AD 9361 Fast Attack AGC Transition From State 2 to 3, and 3 to 5?

    A few questions about how AD9361 Fast Attack AGC transits from State 2 to 3, then from State 3 to 5:

    Q1) According to UG671, Fast Attack AGC locks the gain upon entering State 3. How does the AGC determine that it should exit State 2 and enter into State…

  • ADE7880如何采集3相3线制电源的相电压?


    你好!

    想采用ADE7880采集电机输入的三相三线制(无中线)供电,电机也不带中线。这种情况下,输入ADE7880的每相电压以什么作为参考?该参考能否和ADE7880可否直接连接?谢谢

  • ADE7880 3相3線式 各相總諧波失真ITHD、VTHD如何計算

    各位先進好

    小弟最近在使用ADE7880諧波功能 在三相四線式量測各相ITHD與VTHD都沒問題

    在測試三相三線式(Delta接)時 所獲得的ITHD也可以正確計算出來

    但在VTHD的部分無法從數據上得到一個正確的數值

    後來嘗試從XVRMS跟FVRMS來自行計算 但也無法獲得正確的結果

    想請問各位先進是否有其他方式可以得到三相三線式的VTHD數值呢 謝謝~~

  • ADE7880在3相3線式時B接N要如何求B的KW跟PF值

    在3相4線式時抓取KW跟PF都OK.

    可是在3相3線B接在N時,要抓B相KW跟PF都是無值.

    請教要如何求出來,謝謝
