Table 13.1. Secondary measurements
Description Explanation and range Notes
30 Current IL1
31 Current IL2
32 Current IL3 Phase current RMS value,
range:
0 – 192 [A]
33 Ifmax The maximum value out of RMS phase
current in IL1, IL2, IL3 – recorded to the
instance of circuit-breaker activation Signals TZ, ZW or KZ just before
circuit-breaker activation reset the
Ifmax state saved to that moment
34 Current I0 I0 zero current RMS value,
range:
0 – 10 [A]
35 Current Ig RMS zero current in the lateral branch (Ig),
range:
0 – 10 [A]
36 Voltage U0 U0 zero voltage RMS value,
range:
0 – 130 [V]
37 Voltage UL1
38 Voltage UL2
39 Voltage UL3 Phase voltage RMS value,
range:
0 – 130 [V]
3A Admittance Y0 Admittance of the zero sequence circuit,
range:
0 – 100 [mS]
3B Conductance G0 Conductance of the zero sequence circuit,
range:
0 – 10 [mS]
3C Susceptance B0 Susceptance of the zero sequence circuit
range:
0 – 10 [mS]
3D Active power P3 Three-phase active power RMS value (1-sec.)
range:
0 – 10 000 [W]
Power value as before the sign
indicating the direction of energy flow
fed to busbars (+), sourced from
busbars (–).
Power indication is an average over 1-
second period
3E Reactive power Q3 Three-phase reactive power RMS value (1-
sec.)
range:
0 – 10 000 [Var]
3F P3 15 min cz Three-phase active power RMS (average over
15 minutes)
range:
0 – 10 000 [W]
Power calculates as a sum of marked active and
reactive powers of L1, L2 and L3 busbars,
multiplied by 1.5, and converted into a moving
average over 15 minutes. Power indication is a
negative sign in 2nd and 4th quadrant of the
coordinate system.
3G Q3 15 min br Three-phase reactive power RMS (average
over 15 minutes)
range:
0 – 10 000 [Var]
3H Frequency Frequency 45 - 55 [Hz]
3I Derivative df/dt Derivative df/dt 0.1 – 25 [Hz/s]
3J Voltage U12
3K Voltage U23
3L Voltage U31 Line-to-line voltage RMS value,
range:
0 – 130 [V]
3M Current Imax
3N Current Imin
3O Voltage Umax
3P Voltage Umin
3Q Voltage U0 2 Voltage U0 in section 2 [VT-2]
