Figure 7-19 Selection of measured values on the front — example
The measured values are divided into the following groups:
01
Operation. pri Operational measured values, primary.
03
Impedance Prim Operational impedance, primary;
04
SynchrCheck,pri Measured values of synchronism check, primary;
11
Operation. sec Operational measured values, secondary;
12
IEE,secondary Measured values of earth fault, secondary;
13
Impedance Sec Operational impedance, secondary ;
21
Percent Operational measured values, in percent of operational
nominal quantities;
31
Demand Long-term average values, in primary values;
32
Min/Max Demand Minimum and maximum average values with date and time
indication of moment of occurrence, in primary values;
33
U/I,Min/Max Minimum and maximum values of voltages and currents
with date and time indication of moment of occurrence, in
primary values;
34
p,cosϕ,Min/Max Minimum and maximum values of the actve, reactive and
apparent power of the frequence and the power factor;
41
Thermal Meter Thermal measured values of the overload protection, if
available;
51
User Defined Measured values that are defined by the user during initial
setting of the device (see Section 5.2).
