READING VARIABLES (Read)
Inside the Read menu it is possible to read the values of the measurements and all the parameters
defining the operation of the relay.
T
his menu contains the following sub-menu options:
Currents
I/O block

Self-test
Currents
The following information is available:
Reading Direct Reading reference for the primary currents (Amperes)
Inp value 200 Nominal phase CT primary current (in the example 200 A)
Inp unit A Phase CT primary current unit of measurement (e.g.:100 A)
IEnp value 100 Core balance CT nominal primary current
IEnp unit A Core balance CT primary current (in the example 100 A)
IL1 0.000 A/In Actual RMS value of the L1 phase current
IL2 0.000 A/In Actual RMS value of the L2 phase current
IL3 0.000 A/In Actual RMS value of the L3 phase current
IE 0.0000 A/Ien Actual RMS value of the residual current
Note: according to the selected reading mode, all the currents are displayed with reference to the CT’s nominal current (Relative viewing mode) or
directly as primary ampère (Direct reading mode).
In the SIF5600 two-phase versions, the IL2 current is not measured and a null value is shown regardless of the real value of the current flowing
in the phase without the CT.
