Nemate zkusenosti s mericem energie ADE7758?

[k.novo]

Take me to zajimalo a tak jsem dotaz preposlal do AD, primo cloveku,ktery patri do tymu, ktery ADE navrhoval.
Popravde jsem cekal odpoved jdouci vice do hloubkym idealne s analyzou co pujde vycist z registru pokud misto 3 fazi budu merit 3x jednu L.
V kazde pripade odpoved je zde.


This IC is designed for 3 Phase Voltage applications where the Voltage at shifted in phase by +/-120 degrees relative to phase A. Some of this properties of the system is in built into the IC.

Please note that the Watt hours measurements on 3-Phase are phase dependant.
This may not be the best approach. But you may be able to take Voltage and current measurements only, if the application is a single phase application.




>Analog Device nabizi meric energie pro trifazove rozvody ADE7758, ktery
uklada namerene udaje separatne pro kazdou fazi a i jinak se tvrazi
jako tri nezavisle merice.
Myslite, ze by ho bylo mozne pouzit i jako watmeter pro mereni tri spotrebicu
na jedne fazi?
