你好

想使用 ADE7878 ,  AC输入电源为DELTA的配置 .    （之前使用AD7953  WYE 的电源输入   VAP 接 L1  ,    VBP 接 L2, VCP 接 L3 ,  VN接 中性线   , 可以量测 L1 , L2,L3 的电压 ）

1. 依照下图 Phase B 当作共地 ,  这样不就量不到 PHASE B的电压 ？

Hello

I Want to use ADE7878, AC input power supply is DELTA configuration. (Before using AD7953 WYE power supply input VAP to L1, VBP to L2, VCP to L3, VN to neutral, you can measure the voltage of L1, L2, L3)

1. Use Phase B as a common ground according…

Hi,

I had a project which uses 7878, and a calibration software was already there.

Now the metering chip is replaced with 7880, can the same calibration software be applied?

Or can any minimum change of that calibration software?

Regards

Hi
We are currently developing a series of energy monitoring units with either CT or Rogowski Coil (RC)current sensing. It is for 3 phase 4 wire grid systems, based on ADE7878. As the units are delivered without matched CT / RC current sensors, we need…

Hi Team,

We are working on a three phase power monitoring project. we selected ADE7878 for the power monitoring,

Can please suggest the current transducer for our requirement.  

Specification, 3-ph 4 WIRE 415V AC 50hz, 16A Each Phase.

Please suggest the…

Hello,

We are working on a new energy meter project for commercial and industrial use, which requires the measurement and recording of both positive and negative (Import and Export) value of Active, Reactive and Apparent power.

To achieve this, every…

Hi,

I am designing energy meter by using ADE7878. ADE7878 works well in my previous design with differential inputs to IAP, IAN,IBP and IBN, and ICP and ICN.

But in my new design, I have to use single ended input to ADE7878.

My questions are:

1. Can…

Hi,
I am trying to complte a calibration for ADE7878 using AN-1076.
There were no problems with the VGAIN (IGAIN) registers calibration,
but with offset calibration (VRMSOS) there were difficulties.
I have the following initial data:
 Vmin = 38(V)
 VRMSmin =…

Hey guys. I need to replace one IC that has been used in one of the projects. The IC is ADE7878 Energy metering IC that can be used to supply 3 phase active power to the controller for processing.

However, I am looking for its alternate, and I find in…
