Hi,
I'm working on single phased AC current and, recently I've figure how to correctly read current (see dedicated topic about CS11 sensor).
And now, it could be great if I could read all of the other variables too : frequency, voltage, etc.
According to shortcut, and ACPower instruction's help, to read it you need both current transformer (like the CS11) and potential transformer.
But I just can't find what kind or where to find these sensor : somebody have an idea ? If I google "potential transformer" I see big, very big stuff, for national electric distribution.
Thanks,
bye.
