“Despite the Covid-19 pandemic, Camille Bauer Metrawatt continues to improve and innovate to respond to positive market feedback and international trends. The quality of energy is of growing importance, in particular to ensure security of supply in the areas of electricity production, distribution and consumption. By providing the appropriate measurement technologies, Camille Bauer Metrawatt contributes to maintaining and continuously improving the security of supply, ” says one within the company.
Linax PQ5000-Mobile is accessible on tablet without additional software (directly via a web browser). The use of a single control key increases efficiency.
An inverter in the event of a power failure
It is not uncommon for the supply voltage to be briefly interrupted when measuring power quality, especially with a portable device. In particular, the power plug may fall out of the socket or be unplugged by mistake. Although it often occurs for trivial reasons, the problem can, however, have a considerable influence on the result of the measurements. Thus, during a measurement campaign in accordance with the EN50160 standard, which normally lasts seven days, the results may be incomplete. An inverter has therefore been integrated into the Linax PQ5000-Mobile to easily withstand an outage of 5 x 3 minutes. In the event of a problem, it provides sufficient time to reconnect the plug to the outlet while the meter continues to record without interruption. Battery life is approximately 3 to 5 years.
All power quality analyzers from the Linax PQ range can now be optionally equipped with an inverter.
Remote access via a secure connection
More and more often, measurements taken with portable devices are doubled as a remote process. It is therefore necessary to have a qualified person on site for the measurements of the electrical installation and another, who may be in a completely different place, to start and end the series of measurements and to record the corresponding data via the Internet. Applications of this type must be implemented in a secure manner.
For this reason, Camille Bauer Metrawatt has set up secure access to the gateway with a SIM card. It allows remote measurements anytime and anywhere via a VPN tunnel. Real-time data (from the event recorder, relating to energy flow, interim reports, alarms, etc.) can be viewed at any time in complete safety, which allows the quality of the power supply to be quickly detected electric. Compliance reports, for example according to EN50160, can be generated without external software. Finally, the measurement data can be easily saved to another location thanks to the VPN connection.
Programmable recording duration of events
In addition to compliance with current standards, customers increasingly want to customize parameters and results for evaluating and analyzing power quality data, which has led Camille Bauer Metrawatt AG to introduce several new functions.
Time-based monitoring of statistical conformity assessment (e.g. according to EN50160, IEC61000-2-2, GB / T, IEEE519, a customer specific protocol, etc.) can now be set in 10 minute periods. This novelty also makes it possible to monitor the energy quality in the short term according to current standards.
To make events even more readable, users will in the future be able to configure the output graphics using a programmable recording period as a reference. It includes the root mean square values of ½ ≤1 s before and ≤180 s after the triggering of a power quality event. In addition, example values of ≤1 s before and ≤5 s after triggering can be set. It is then possible to zoom directly on the events in the browser to display the important values at a higher resolution, and therefore to make them more readable.
All these properties can be entered intuitively directly on the screen of the Linax PQ device or directly in a web browser on PC, tablet or smartphone, without requiring complex and expensive additional software.
IT security through specific protection measures
New protection mechanisms have been introduced to limit risks such as theft, falsification or fraudulent use of data. These include role-based access rights, which prevent fraudulent access to different functions, views and data. Users therefore only have the rights strictly necessary to carry out their tasks.
The audit log function records additional security-related processes and stores them securely on a system recorder. In addition, the Syslog protocol can be used to transfer the contents of the audit log to a central server for network monitoring. Access authorization can be limited to a maximum of 10 computers with access rights.
Web access to devices can be done via an https address. The messages are then encrypted and decrypted using a certificate provided by Camille Bauer Metrawatt or specific to the client.
Together, these protective measures ensure high security while covering a wide variety of applications.
The web interface of all Camille Bauer Metrawatt devices has a uniform structure. The user can thus easily perform various operations via a single interface.
