• 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~~

  • About BAPASS pin of AD9516-3

    Hi,

          In a recent work,we found several pieces of AD9516 that did not have an clock output . At the same time, their BAPASS pin voltage is 1.8v, while the working AD9516 BAPASS  pin voltage is 2.5V.

    Could you give me some advice, please?

  • 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

  • Get video simultaneously from 3 cameras using ADV7180. Possible ?

    Hi,

    In my company, we are developing a video security system using 3 analog cameras, so we decided to use ADV7180 (40 pin version).

    The three analog video inputs are multiplexed, so we wonder if we can get the video from the 3 cameras simultaneously. O…

    Please provide the SDI and SDO data for the entire command step sequence and the schematic.

    Also, please provide a scope shot of the write and read frames. 

    It is certainly not possible for the register readback to be different from what you have written…
