4k tg(Fi) Q3/P3
Tangent of instantaneous phase angle for transformer
load (with sign), calculated as the ratio of 1-second

4o Σ I1 shutdowns
4p Σ I2 shutdowns
4q Σ I3 shutdowns
4r Σ I4 shutdowns
Cumulated sum of RMS currents shut down by the
master switch.
Range:
Σ I1: 0 – Igr1*thetaIf [kA]
Σ I2: Igr1*thetaIf – Igr2*thetaIf [kA]
Σ I3: Igr2*thetaIf – Igr3*thetaIf [kA]
Σ I4: Igr3*thetaIf – 192*thetaIf [kA] , where:
Igr1 – Igr3: circuit-breaker limit currents;
thetaIf: transmission ratio of phase current
transformers;
For the purpose of turn-off currents, the
maximum value of current RMS values in L1, L2
and L3 (after a turn-off impulse is sent to the
circuit-breaker coil to the moment of power cut)
is used. The cumulated sum means current
values converted by means of the transmission
ratio into the grid primary side.
The value will be stored regardless of duration
of auxiliary supply interruption.
