Outline
The monitoring function is provided to measure the number of power quantities and statistics
data obtained within the VCT and BI circuits†. When the measuring instruments start
measures power quantities, mathematical means is applied to the data from the VCT so that
the data are shown accurately on the IED screen.
†Note: The VCT/BIO structures and their features are discussed in Chapter Technical
description .
Metering data (Metering group)
Several abbreviations are screened for metering data, which is tabulated below Table
1–6
.
1
Note: Terms ‘I
0
(i.e., 3I
0
)’ and ‘V
0
(i.e., 3V
0
)’ are calculated using three-phase quantities.
2
Note: The ‘I
e
’ and ‘I
em
’ are obtained usually with corresponding ‘I
e
’ and ‘I
em
’ circuits in
the VCT.
3
Note: ‘CH2’ is available when two signaling modules exist in the IED, which is
dependent on the model. Check the ordering number at the C position referring to
the ordering (See Appendix: Ordering )
4
Note: Those metering items are provided for the special models, which are designated at
ordering made.
5
Note: Positive-sequence V1, which represents power system, is used to measure the
frequency.
6
Note: Check the ordering number at the G&T position referring to the ordering (See
Appendix: Ordering)
