Siemens SICAM Q100 7KG95 Series Manual page 33

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)
Detected time stamp
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.
