In a fully configured 7SJ63 device, the following measured values are available:
• Ia, Ib, Ic, In: phase currents and ground current, primary in A and kA, secondary in
A and in % of the device nominal current.
• I
: ground current, primary in A and kA, secondary in A and in % of the device nom-
Ns
inal current, only for devices with the sensitive ground current measurement input.
• I
, I
: positive and negative sequence components of the currents, primary in A and
1

kA, secondary in A and in % of the device nominal current.
• Va, Vb, Vc: phase-to-ground voltages, primary in kV, secondary in V and in % of
V
/√3, assuming that the phase-to-ground voltages are connected.
Nom
• Va-b, Vb-c, Vc-a: phase-to-phase voltages, primary in kV, secondary in V and in %
of V
.
Nom
• 3V
or Ve-n: displacement voltage, either directly measured or calculated as
0
3V
=(Va + Vb + Vc), primary in kV, secondary in V and in % of V
