Siemens expands its power monitoring system from the Sentron portfolio by adding the 7KM PAC5100 and 7KM PAC5200 measuring devices. Designed for use in industrial plants or buildings, the new devices record not only the entire energy data but all relevant parameters for assessing the power quality.
A constant power supply in a defined quality is essential for the interference-free operation of numerous industrial production and automation processes as well as for the safety of electric loads. Potential internal or external interference in the power grid is identified by the new measuring devices at an early stage. Thus, it can be responded to immediately.
The recorded details can be reported to the Siemens power monitoring system. Consisting of TÜV-tested, communication-capable hardware components and powermanager software for the visualization and analysis of data, the power monitoring system creates the technical basis for an operational energy management according to ISO 50001.
The compact 7KM PAC 5100/5200 measuring devices are used at the power supply or on an individual plant. There, they can record data on the mains frequency, on active, reactive and apparent power, on the reactive and active power factor, on phase angles, the harmonics of alternating voltage and alternating current up to the 40th order, and on the distortion of alternating voltages and alternating current.
The 7KM PAC5200 measuring device comes with mean value, event and fault writing functionality, a logger for quality standard EN50160, and 2 Gigabyte (GB) of data storage for the documentation of long-term data. Users can read out all the recordings directly on the device as well asuse the standard data formats PQDif and Comtrade for analysis purposes. Power quality events are presented in ITIC(CBEMA) curves amongst others.
Plant operators can use the collected data to check if the power delivered by the energy provider has the contractually agreed quality and to renegotiate the contractual terms if necessary. Machine-builders, on the other hand, benefit from the devices to safeguard the functionality of their plants world-wide – regardless of country-specific fluctuations in the power supply.
The measuring devices are commissioned quickly and easily. They have electrically separated voltage inputs and are equally suitable for installation in control panels and mounting on standard rails. They fulfill the degree of protection IP40. Parameterization, diagnostics, analysis, and report creation are performed by the integrated web server.
All data are recorded in standard-compliant format according to IEC 61000-4-30 and are comparable independent of the manufacturer. One of many recordings is the monitoring and analysis of the power quality standard EN50160 directly in the device or via the web server. Communication with the devices is handled via the Modbus TCP protocol.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
