Reactive Load for ADE7758 Measurements

[Sanath Embedded]

ade7758 waveform

Hi ,

I am currently working with ADE7758 for the Three phase measurements. So finally I am able to read the values for the per phase IRMS, VRMS, Active Power & energy.
So here for the Reactive power calculations , please let me know like what type of known Reactive load can be connected for the sample ADE7758 measurements.

Regards

ade7758 crystal

sir i am using ATmega16L micro and i had purchased the ADE7758 and connected the hardware.


i had made hard ware for ADE7758
AVDD & VDD ---- 5volts. and requried ressistors and capacitors
and connected

DOUT(ade7758) ---- MISO(mega16) configured as input
DIN (ade7758) ---- MOSI(mega16) configured as output
SCK(ade7758) ---- SCK(mega16) configured as output
CS (ade7758) --- GND
CS SCK(mega16) ---VCC(5v)

i had initialized my microcontroller as master,MSB first,Fosc/128 for 8MHZ crystal and iam able to see the wave forms on SCK and MOSI pins according to the sent data, but i am not getting any response from ADE and no waveform on MISO pin. i am trying to read the default data in the WAVMODE(14h) register but i am getting all zero's.

i had initlized ADE also with OPMODE and communication register,

plz help me

Re: ade7758 crystal

Hi
did you find a solution for the WFORM register in the meantime.
I have the same problem.
If you have the solution please give me a hint, thanks.
