13.3.3 Setting guidelines
The parameters for Fuse failure supervision VDSPVC are set via the local HMI or PCM600.
The voltage input type (phase-to-phase or phase-to-neutral) is selected using
ConTypePilot parameters, for main and pilot fuse groups respectively.
The settings
VBase . Set VBase to the primary rated phase-to-phase voltage of the potential voltage
transformer.
group, that is used by VDSPVC (60), is set by the setting parameter
Bay control REC670
Application manual
The connection type for the main and the pilot fuse groups must be consistent.
Vdif Main block , Vdif Pilot alarm and VSealIn are in percentage of the base voltage,
VBase is available in the Global Base Value groups; the particular Global Base Value
