BESTview for Windows
™
is a free software
application program that enables communication
between PCs and BE1-BPR relays. Through
BESTview, you can retrieve and display
COMTRADE oscillographic fault data, access the
front panel from a remote location to change
settings, retrieve a computer file of the relay
settings, or send a computer file to the relay
to perform all relay settings.
