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 400 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 400
when it has new recordings ready. SPA-ZC 400 reads the actual data from the
relay as a background process and stores the data as COMTRADE files in its
own file system.
