2. Product Description
2.1 General features
DS1 are dry air insulated special purpose capacitor switches for
indoor installation. Please refer to the corresponding technical
catalogue code (1VCF000580) for the electrical performance
data.
For special installation conditions, please contact ABB. Please
also note that the
apparatus is unable to make or break fault
conditions and that protection on the supply side must
always be installed
.
The following photos illustrate the DS1 main assembly. DS1
is a special purpose capacitor switch specifically designed for
managing capacitive loads in symmetric and balanced systems.
The load layout must be the full capacitive, star configura-
tion and floating center-load type.
The device uses diode-switching technology and is dry air
insulated (see
Pressure Monitoring
section for details).
One additional upstream voltage sensor for MV network
synchronization is required for correct installation (see specific
sensor characteristics in the following section).
