Tonight I moved the current sensor from my test load (150W light bulb) to a real circuit in my main distribution box. That circuit is currently pulling nearly 500W at 121Vrms. It is logging data to a CSV file. It … Continue reading →

I found the cause of my power switching from positive to negative. I would scope the current and voltage inputs one day and they would be in phase. The next day or even later that day they would be 180 … Continue reading →

As I kind of suspected, Analog got back to me and informed me that the ADE7763 was a very mature product and that the reversal of IRMS and VRMS was never reported. Now unless NOBODY has ever tried to read … Continue reading →

I last left with a puzzle on my mind. The VRMS and IRMS registered seemed to be reversed. Changing the load did not vary the IRMS register by rather the VRMS. I figured I had screwed something up in the … Continue reading →

In my last port I alluded to the mysterious swapping of the voltage and current channel. When I read the Vrms and Irms channels under various loads, it is the voltage channel that changes significantly and not the current. I … Continue reading →

My ADE7763 is connected to an Arduino and I am now working on the interface code to aid in system testing. I sent several hours today with my mixed signal scope (2 channels of analog and 16 digital) debugging. What … Continue reading →

Just started the first system testing of the ADE7763. What I mean is rather than just working on the SPI or other subsystems, I am using the chip as it would be in real life. I have the voltage and … Continue reading →

I have had an offline conversation with a reader about my endeavors with the ADE7763. Their application is similar to mine, but rather than monitoring at the breaker panel they wish to monitor (and control) at the plug level. I … Continue reading →
