Regarding the ridethough capability of Dynamic Voltage Restorer

[srakesh]

Hi,

Guide me in understanding the ride though time and sag correction capability of Dynamic voltage restorer DVR30060400M.

In the datasheet it is mentioned that the Sag correction capability - for 3 phases 60 % for 30s and in the same datasheet it is mentioned that the ride through time - 40 ms.

When the DVR can compensate the sag of 60% for 30s, the ride through time achieved is 30s, but in datasheet ride through is mentioned as 40ms. Please clarify  what is the difference between sag correction capability and ride through time ?

Query : for the voltage sag /dip of 55% (i.e. 45% voltage remaining) with the sag duration of 80ms. Whether this sag can be mitigated/ride through with this Dynamic Voltage Restorer?
