Hello, everyone!We use ADE7868A for 4-element 4-wire electricity meter. We need to detect neutral current mismatch in this meter, so we expect that we will use Neutral Current Mismatch function of ADE7868A.
We made a PCB, it was not big deal, as we used…
Hi all,
I'm designing power meter and analyzer. I consider using one of the above mentioned metering ICs.
I was looking at the datasheet for detailed technical specifications, however the datasheet was little confusing.
I need to have an exact…
Hi everybody,
We´re moving from ADE7753 to ADE7868A in our energy meter design as we needed to measure total harmonic distortion. In the product selector, the ADE7868A states it measures total harmonic distortion, but in the user manual I can´t see a…
Thanks, Gary
Our product needs to monitor a distribution system which will be a mix of single phase and three phase loads and sources. We are planning to use a combination of ADE7868A, ADE7953 and ADE7816 devices on a common SPI bus. The project is too…
Hi,
I suggest you build the program to monitor IRQ1\ pin of the ADE7868A. After power up, wait until IRQ1 goes low, then you do the SS\pin toggling as above. This will ensure the chip sees that you want to use SPI. I am afraid that the chip is not ready…
Hello everyone,
we are experiencing some problems with SPI communication between a STM32F4 MCU and an ADE7868A.
The connection is straight between MISO, MOSI, SCK, /SS, /RESET.
We do what follows:
Set /SS high
Reset the ADE7868 toggling low /RESET…
Hello
I'm currently using AD7878A with atmel microcontroller. communication between the two is through SPI (isolated using isolators) and power domain of ADE7878A and Microcontroller is different. In datasheet it has written that
"it is necessary…
Hello Hariharan,
thanks for your answer.
1. These currents are provided through a set of incandescent lamps. We have an accurate CT based meter reading the current flowing in the phase and we also verified with an ammeter in series. To achieve the…
Hi Sai,
For measureing a 3 phase system at 400Hz I would recommend using a part such as the ADE7858A or ADE7868A if you want to use CT's to measure the current. If you rather use shunts for the current measurement then I would recommend the ADE7978 with…
