5.2. Configuration of over voltage function (SWELL)
This function is used to detect over voltage according to EN 50160 standards (Voltage characteristics of electricity
supplied by public distribution systems)
Example : Discover over voltage (SWELL) with a threshold in 10 % and a hysteresis of 2
%. Reading information with communication
DIRIS configuration (see instruction manual : 876 588) :
 Over voltage threshold (SWELL) = dAtA SAG 10 % )
 Over voltage hysteresis = dAta HySt SAG 2 %
Reading of the information is made in the same way as for voltage dips (see 5.2)
 = 10 %
Un
Threshold (Un + 10 % de Un)
Hysteresis (Un+ 2% de Un)
