Application
The SICAM Q100 is a multifunctional device for the detection, processing, and evaluation of measured quan-
tities and events according to IEC 61000-4-30, class A, power quality (PQ) standard. The energy management
functions also allow determining load profiles and setting up to 6 tariffs. The device is used on all voltage levels
of power supply systems. SICAM Q100 is used in 1-phase systems and in 3-wire and 4-wire systems (with neu-
tral conductor). The device is mainly used by power utilities but also in other industrial and commercial sectors.
In addition to the measuring function, SICAM Q100 features various recorders (for example, measured value
recorders) to record the measured quantities and the load profile in programmable time intervals. Long-term
data and events are analyzed and output as report according to power quality standards, for example EN
50160.
The input circuits for voltage measurement are galvanically isolated and can be used in IT, TT, and, TN
networks. To ensure galvanic separation for current measurements, the lines connected to the current
measuring inputs are galvanically separated from the current transformers.
The measurements are obtained from the alternating quantities of current and voltage supplied to the AC
inputs. When no external voltage and current transformers are used, the device can process rated input
alternating voltages of up to V
P-N
= 230 V (110 V for UL condition) and rated input alternating currents up to 5 A.
The integrated web server can be used to set the parameters and display the measured values on HTML pages
from the connected computer. With the internal graphic display, a limited parameterization via softkeys can be
carried out on the front panel and measured values can be output via the display.
To communicate with the systems control and other process automation equipment and to transmit operational
measured values, metered values, indications, load profiles, etc., the device features an Ethernet interface and
an RS485 interface.
Measured quantities:
• Alternating voltage and alternating current
• Unbalanced of alternating voltage and alternating current
• Active, reactive, and apparent power
• Active, reactive, and apparent energy
• Power frequency
• Phase angle
• Power factor and active power factor
• THDS (Subgroup Total Harmonic Distortion) of alternating voltage and alternating current
• Harmonics and interharmonics of alternating voltage and alternating current
• Flicker acc. to IEC 61000-4-15
• Transients
• Mains signalling voltage (MSV)
The uncertainty of operational measurements of the measured quantities is defined as per IEC 62586-1 product
standard, class A (leading standard), the IEC 61000-4-30 power quality standard, and the IEC 62586-1, Ed. 1
standard.
For detailed information on measured quantities and measured values, see Chapter 4.2 and the technical data
in Chapter 13.1.
