Power quality recorder SICAM Q100

Features & functions

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. The measured variables can be output to a PC or system control via communication interfaces or shown on a display. In addition to the monitoring function, the SICAM Q100 all-in-one device provides a combined recording and evaluating function: measured values can be recorded in parameterizable time intervals with various recorders such as power quality and fault recorders. Longtime data and events are evaluated directly in the device and displayed as a report according to the power quality standards (e.g., EN 50160).

Applications

Power quality - supply quality

 

Quality is generally regarded as an important aspect of any power supply. Insufficient power supply quality has a negative impact on operational processes and operational safety of consumers connected to the network and can entail serious consequences, ultimately resulting in increased costs for the user and supply utility.

The EN 50160 power quality standard describes the main voltage characteristics at customer's supply terminals in public low, medium and high-voltage systems. Comprehensive acquisition and documentation of parameters relevant to the supply quality is a necessary step required to identify possible weak points and initiate appropriate measures to eliminate them.


Application

 

The SICAM Q100 device is used in single-phase as well as in three-wire and four-wire systems (with neutral conductor). The device is applied wherever comprehensive measurement of supply quality is necessary - at power utilities as well as in industry and trade sectors.
