Metering data (Metering group)
Several abbreviations are screened for metering data, which is tabulated below Tables
1–4
.
1
Note: ‘Ie’ and ‘Iem’ are taken usually with corresponding ‘Ie’ and ‘Iem’ circuits in VCT.
2
Note: Terms ‘I0 (i.e., 3I0)’ and ‘V0 (i.e., 3V0)’ are calculated using three-phase quantities.
3
Note: Frequency is measured with positive-sequence V1, which represents power
system.
4
Note: The metering items are dependent on the models designated at the ordering.

Metering information on the screen
The user can examine the values provided by the metering function on the IED screen; Figure
9.2-1 illustrates the information about currents. A reference phasor is defined to examine a
complex data in the metering and a positive-sequence voltage (V1) is defined as the reference.
The metering function has minimum sensing threshold; thus, the user shall notice that zero
(0) is displayed, if the provided data is lesser than the threshold.
