Data Type This column defines the basic nature of the sampling rate. For

a waveform channel, select “Y-Waveform”, for a Trend (like

a RMS value), select “Y-Trend”. The remaining options are

“X-Time” which you should not use for any channel in a

COMTRADE file and “Y-Digital” which is used to denote

Digital status channels in a COMTRADE file. “Y-Digital”

should not be used for analog channels.

Group Use this setting to group parameters together into individual

measurement points. The number “1” should always be used

for single-point measurements.

Example: A file contains voltages from two measurement

points: AV1, BV1, CV1 and AV2, BV2, CV2. In this case,

you need to set Group number=1 for parameters

AV1,BV1,CV1 and Group number=2 for parameters

AV2,BV2,CV2. As a result of using more the one group,

there will be several sites created in the Dran-View 6

document, wherein each site will contain an individual 3-

phase system measurement.

Prefix Select “None” if the channel is not scaled. Select ‘k’ (kilo) if

the data has been divided by 1000 prior to being stored (other

Greek prefixes are also available).
