Using Disturbance Recorder files

In case of, for example, abnormal events on the electric line, the protection relay can
generate data for a graphical presentation of the detected phenomenon. These
presentations are stored by MEDREC16, the Disturbance Recorder function block
of the relay. When connected to a relay with the MEDREC16 version K or newer,
SPA-ZC 402 can load the recorded data and convert it to standard COMTRADE
files (in year 1999 format). The conversion is done automatically and the
Disturbance Recorder Ready signal is sent to IEC 61850 client after new files are
ready to be read.
A relay with compatible MEDREC16 function block notifies SPA-ZC 402 when it
has new recordings ready. SPA-ZC 402 reads the actual data from the relay as a
background process and stores the data as COMTRADE files in its own file system
under the directory C:\COMTRADE.
