ABB 615 Series - Settings

to primary peak value units when the protection relay converts the recordings to the
COMTRADE format.
COMTRADE is the general standard format used in storing disturbance
recordings.
The binary channels are sampled once per task execution of the disturbance recorder. The
task execution interval for the disturbance recorder is the same as for the protection
functions. During the COMTRADE conversion, the digital status values are repeated so
that the sampling frequencies of the analog and binary channels correspond to each other.
This is required by the COMTRADE standard.
The disturbance recorder follows the 1999 version of the COMTRADE
standard and uses the binary data file format.
