    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. Customers expect maximum availability of electrical power, reflecting a consistently high standard of quality. For example, in power system protection, it is becoming increasingly difficult to distinguish between critical load cases and short circuits with minimal fault currents. The demands on optimum use and the corresponding parameterization of protective devices are rising. Intensive evaluation of available information from secondary equipment (using fault recorders) is therefore essential. Only this way can today’s high levels of reliability and availability in power transmission and distribution networks be ensured for the future as well.

    There is also concern that the growing use of power electronics often has a noticeable impact on voltage quality. The resulting inadequate voltage quality leads to interruptions, production losses and high consequential costs. Compliance with the generally valid quality criteria for power supply systems as defined in the European standard EN 50160 is therefore vital. The basis must be reliable recording and assessment of all quality parameters. Weak spots and potential fault sources can be identified early on and systematically eliminated. With the software solution SICAM PQS, Siemens is setting new benchmarks here: 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. This gives you a quick and uncomplicated overview of the quality of your system. With SICAM PQS, you can keep an eye on all relevant data, including fault records as well as all power quality measurement data. SICAM PQS can also be easily expanded to create a station control system for combined applications.
