Siemens SICAM Q100 Power Quality Instrument/Recorder popularly known as Q100 power quality recorder multifunctional measuring devices are used for visualization, acquisition, evaluation & transmission of electrically measured variables such as alternating voltage, alternating current, power, frequency, harmonics etc.  The acquisition, processing & accuracy of measured variables and events are performed in accordance with the IEC 61000-4-30 Class A power quality measurement standard.

The measured variables can be output to a PC and also the system control with the help of communication interfaces and it can also be shown on display. In addition to its monitoring function, the Siemens Q100 Power Quality Instruments are all-in-one devices that offer combined recording and evaluating functions: measured values are recorded in parameterizable time intervals with different recorders (power quality and fault recorders). Longtime data and events are evaluated directly in SICAM Q100 Power Quality Recorder and displayed as a report in accordance with the power quality standards (e.g., EN 50160).

Siemens Q100 Power Meter Applications

Power Quality – Supply Quality

Quality is generally regarded as an essential aspect of any power supply. Insufficient power supply quality generally has a negative impact on operational processes as well as the operational safety of consumers associated with the network. Siemens SICAM Q100 Power Quality Instrument/recorder can entail major consequences, which can ultimately result in increased costs for the user & supply utility.

The EN 50160 power quality standard helps in describing the main voltage characteristics at the supply terminal of customers in public low, medium & high-voltage systems. Documentation of parameters relevant to the supply quality and Comprehensive acquisitions are necessary steps for identifying possible weak points and initiating appropriate measures to eliminate them.

Siemens Q100 Power Meter Application

The SICAM Q100 devices are used in single-phase, three-wire and four-wire systems (with neutral conductor). These devices are applied wherever comprehensive measurement of supply quality is essential – at power utilities and industries as well as trade sectors.

Many electronic devices & automation systems in industrial production plants are delicate towards voltage variations & dips in the power supply which are usually caused by the unexpected connection of energy sources like renewable energy & large energy consumers. The production system itself can also cause faults and feed them back into the distribution system. The plants can be shut down and you will suffer major production loss. Power quality needs to be continuously measured & analysed to detect any type of unexpected risks early on.
