Disturbance recorder
ABB Network Partner AB
1MRK 580 141-XEN
Page 7 - 71
Version 1.0-00
The recordings can be divided into two parts, the header and the data part.
The data part contains the numerical values for the recorded analogue and
binary channels. The header contains clearly written basic information on
the disturbance. A part of this information is also used by REVAL to
reproduce the analogue and binary signals in a correct and user-friendly
way. Such information is, primary and secondary instrument transformer
ratings.
This information is included in the header:
Table 1 is a summary. For detailed information, see the User’s Guide for
REVAL (1MRK 501 003-UEN).
