Technical manual
The recorded disturbance is now ready for retrieval and evaluation.
The recording files comply with the Comtrade standard IEC 60255-24 and are divided
into three files; a header file (HDR), a configuration file (CFG) and a data file (DAT).
The header file (optional in the standard) contains basic information about the
disturbance, that is, information from the Disturbance report sub-functions. The
Disturbance handling tool use this information and present the recording in a user-
friendly way.
General:
• Station name, object name and unit name
• Date and time for the trig of the disturbance
• Record number
• Sampling rate
• Time synchronization source
• Recording times
• Activated trig signal
• Active setting group
Analog:
• Signal names for selected analog channels
• Information e.g. trig on analog inputs
• Primary and secondary instrument transformer rating
• Over- or Undertrig: level and operation
• Over- or Undertrig status at time of trig
• CT direction
Binary:
• Signal names
• Status of binary input signals
The configuration file is a mandatory file containing information needed to interpret
the data file. For example sampling rate, number of channels, system frequency,
channel info etc.
The data file, which also is mandatory, containing values for each input channel for
each sample in the record (scaled value). The data file also contains a sequence
number and time stamp for each set of samples.
