5.2. Configuration of voltage dips function (SAG)
This function is used to detect voltage dips according to EN 50160 standard (Voltage characteristics of electricity
supplied by public distribution systems)
Example : Discover voltage dips ( SAG) with a threshold in 10 % and a hysteresis of 2
%. Reading information with communication
DIRIS configuration (see instruction manual : 876 588) :
 Voltage dips threshold (SAG) = dAtA SAG 10 % )
 Voltage dips hysteresis = dAta HySt SAG 2 %
