Questions answered in these manuals
What is the fault detection threshold for the ADE7761?
The device flags a fault when the phase and neutral currents differ by more than 6.25 %.
How does the ADE7761 indicate a missing neutral condition?
A missing neutral condition is indicated when the FAULT pin goes high.
What is the measurement error of the ADE7761?
The ADE7761 has a typical measurement error of 0.1 % of reading over a dynamic range of 500 : 1.
How does the ADE7761 detect a missing neutral condition?
It continuously monitors the input voltage; when no voltage is present, the FAULT pin goes high to indicate a missing neutral condition.
