control, monitoring and user interface functions. Includes protection
for abnormal voltage and frequency, current unbalance (negative sequence),
and directional power. Sync-check, VT fuse loss and directional phase
and ground overcurrent protection are also provided. Stored targets and
oscillography can be time-stamped. Dual RS-232 and RS-485 communication
ports provide user-interface capabilities. Optional modules include the
HMI Module for front-panel operation, and redundant power supply. The
M-3822 IPScom® Communications Software is included for direct serial
or remote communication access. Waveform data can be downloaded using
IPScom, while the M-3801D IPSplot®PLUS Oscillograph Analysis Software
allows for plotting and printing of the downloaded oscillographic data. |
