ENGLISH
The presence of notch-type periodic disturbances in voltage with dv/dt values great-
er than 30% can cause deterioration and even destruction of certain components of
the static var generator, even when they are not in operation and are just connected
to the mains.
Thus, if the presence of these notches is suspected due to having loads that are
prone to creating them, the network must be studied to record the voltage and current
waves under full load conditions for analysis.
If these notches are apparent in the readings, the CIRCUTOR technical department
should be consulted to determine the suitability of installing SVGm static var gener-
ator in the mains.

3.6.- DEVICE TERMINALS
3.6.1.- WALL-TYPE SVGm: SVGm-3WF-xxxM and SVGm-4WF-xxxM
The connection terminals of the Wall-type SVGm model are located on the lower face of the device. The
device has a terminal cover on the mains connection terminals.
