Power Quality


As cer­ti­fied Siemens Power Qual­ity prod­uct Part­ners we gladly sup­port you with the re­al­iza­tion of your pro­jects. Siemens Power Qual­ity prod­ucts are able to in­te­grate seam­lessly into ex­ist­ing au­toma­tion net­works due to their ver­sa­tile com­mu­ni­ca­tion in­ter­faces.

The scal­a­bil­ity range of the power qual­ity prod­uct fam­ily al­lows the re­al­iza­tion from micro ap­pli­ca­tions to self-suf­fi­cient data record­ing sys­tems.



The SICAM P855 multifunctional device is used to collect, display and transmit measured electrical variables such as AC current, AC voltage, power types, harmonics, etc. The measurands and events are collected and processed according to the Power Quality Standard IEC 61000-4-30. The communications interfaces can be used to output the measurands to a PC and the control center or display them on a display.


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).


SICAM Q200 is a network analyzer for high-definition acquisition and assessment of the power quality in electrical power supply systems. It offers algorithms and functions for energy management applications. The device supports continuous acquisition and analysis of all relevant parameters. These results help to identify and implement quality programs to ensure the supply quality. This increases the service life of the equipment while at the same time reducing downtimes.

PQ Analyzer:

The SICAM PQ Analyzer provides comprehensive evaluation options for archived PQ measuring data and fault records. In addition to clearly structured fault record analysis, the fault locator facilitates and accelerates the elimination of faults in the power network. PQ violation reports provide a quick and comprehensive overview of limit value violations. Scheduled reports provide an overview of the development of measuring data over selectable time ranges.


Siemens SICAM PQS allows all fault records and power quality data to be analyzed in one system. The protection of power distribution equipment is crucial in assuring a reliable power supply. Intensive evaluation of available information from secondary equipment (using fault recorders) is therefore essential. There is also concern that the growing use of power electronics often has a noticeable impact on voltage quality. For the first time, it is now possible with an integrated software solution to evaluate and archive centrally and vendor-neutral all power quality data from the field.
