SICAM Q100 is a Class A multifunctional measuring device for monitoring power quality according to the IEC 62586-1 (PQI-A-FI) product standard. It is used to acquire, visualize, analyze, and transmit measured electrical variables such as AC current, AC voltage, frequency, power, harmonics, etc. The acquisition, processing and accuracy of measured variables and events are performed according to the IEC 61000-4-30 Class A power quality measurement standard. Long-term data and events are evaluated directly in the device and displayed as a report in accordance with power quality standards (such as...

Voltage quality (also known as power quality) refers to various characteristics in a power supply system. Voltage quality criteria are defined by a number of technical regulations, such as the EN 50160 power quality standard. These criteria describe the main characteristics of voltage at customers' power supply terminals in public low-, medium-, and high-voltage systems. Ultimately, however, quality is determined by the ability of customer systems to correctly perform their tasks. Most quality problems affect the ultimate consumer directly or are perceived at this level. Today, production plants...

To learn more about data availability and measured variables, refer to the SICAM Q100, 7KG95xx System Manual. 7 - The load profile data for the current and most recently completed periods is output via the communication interfaces. - Data can be transmitted via the Modbus TCP, Modbus RTU Master,...

Products – SICAM Q100 Power quality acquisition and recording Functions of the IEC 61000-4-30 Ed. 2 measurement system SICAM Q100 devices serve to measure voltage quality according to IEC 61000-4-30 Ed. 2 and to perform other measurements in single-phase and multi-phase supply systems. The measurement system is implemented according to Class A, meaning that the functional scope, measuring ranges, and accuracy are those of Class A measuring devices. The basic measuring interval for determining the values of mains voltage, mains voltage harmonics, and mains voltage unbalance is a 10-period interval...

Products – SICAM Q100 Power quality acquisition and recording Flicker: Uninterrupted recording according to IEC 61000-4-15. The following measurements are performed simultaneously for all three-phase voltages: instantaneous flicker Pinst (10/12 measurement interval), short-term flicker strength Pst (10 min), and long-term flicker strength Plt (2 h). Transient recording: SICAM Q100 records temporary overvoltages as transients if the instantaneous value of the primary rated voltage exceeds the parameterized reference value at multiple sampling times. SICAM Q100 records the following data and values...

In addition to standard measured value acquisition, SICAM Q100 quality, as well as power management data for evaluating the offers various recorders for monitoring and analyzing power load profile. Recording Table 2/7 Recorders and applications SICAM - Power Quality and Measurements

Products – SICAM Q100 Recorder types and evaluation Measurand recorder The measurand recorder records measured values for determining power quality as well as various other measurements (for example, minimum/maximum values). Recording of the following measured values can be parameterized in the user interface: ■ PQ measurements for determining power quality ■ Averaging intervals for frequency (permanently set to 10 s) ■ Averaging intervals for voltage, voltage unbalance, harmonics, and interharmonics (30 s, 60 s, 10 min, 15 min, 30 min, 1 h, 2 h) ■ Flicker: Short-term flicker strength P st (10...

Products – SICAM Q100 Recorder types and evaluation SICAM Q100 supports two load profile recording methods: fixed block and rolling block. Fixed Block: The default setting is a 15-minute measuring period; the number of subperiods is set to 1. At the end of each measuring period, the load profile data is calculated, stored in the ring buffer and, if necessary, forwarded or displayed on the user interface. Rolling Block: With this method, a measuring period comprises 2 to 5 subperiods, depending on parameterization. The duration of a measuring period is based on the number of subperiods and the...
