4 Measured Quantities and Recording
4.1 Power Quality Measuring System and Recording System
33SICAM Q100, 7KG95xx, Device Manual
E50417-H1040-C522-A6, Edition 06.2019
SICAM Q100 detects mains singalling frequencies from 100 Hz to 3 kHz. The threshold for detection and
capture is from 1 % up to 15 % of Udin.
The following data and values are determined during the evaluation of the mains signaling voltage in SICAM
Q100 and listed in the window Mains signaling voltage (see chapter 9.4.2.3):
• Time when mains signaling voltage starts to occur (time stamp with date and time)
• The values of the affected phase (a, b, c, ab, bc, ca)

The mains signalling voltage will be recorded if the instantaneous value of the MSV (on the user-specified carrier
frequency) is higher than a given threshold voltage. The recorder will not end until the Total recording duration is
reached.
The 10/12 cycle values of voltages are recorded. For detailed information on calculation of mains signaling voltage,
refer to IEC 61000-4-30.
