Capabilities
PQM-710 has a built-in GPS receiver ensuring real time clock accuracy and an integrated GSM modem that facilitates remote analyzer operation.
An additional trump card of the analyzer is the built-in Wi-Fi communication module, providing a number of advantages: no restrictions on file transfer, no data transfer costs, use of local wireless infrastructure... This gives the user the opportunity to adapt to the conditions prevailing on the site. They can supervise measurements from a convenient location – for example, an area without electromagnetic interference – using a laptop, smartphone or tablet.
Displaying data
PQM-710 can be operated using a touch screen computing device equipped with Sonel Analysis software (Windows) or Sonel Analysis Mobile app (Android). The user can supervise the measurements and conduct diagnostics while maintaining mobility – he doesn’t even have to be near the analyzer. In typical applications, the device plays the role of a remote display and an intermediate storage of measurement data with the functionality of a router. Therefore, the user can also connect to it using a wireless network – for example, to transfer the collected registrations to a desktop computer.
Application
PQM-710 is widely used in the professional power industry. It provides full 4-quadrant analysis, meeting the needs of energy consumers and producers, such as renewable energy, including photovoltaic and wind farms. It enables forecasting failures in distribution networks. It provides analysis of the load capacity of networks and transformers, as well as recording their current states. In addition, it is powerful investment tools. Thanks to PQM-710, the user will obtain the necessary data for development of power infrastructure, predict potential problems, and finally – verify the correctness and quality of implementation.
SONEL ANALYSIS
Sonel Analysis software – application delivered as standard accessory, indispensable for working with PQM-series analyzers. Depending on the mating instrument used, the software enables:
analyzer configuration,
data reading from logger,
preview of network parameters in real time (with capability of reading via GSM modem),
deletion of data in the analyzer,
data presentation in tables,
data presentation in charts,
data analysis and generating reports in compliance with standard EN 50160 (reports) and other user defined reference conditions - also for PV micro-installations up to 50 kW, a breakdown for active power states P>0, P<0 and P=0 and taking into account the graphs Q1=f(U1/Un) and cosφ=f(P/Pn),
independent support of multiple analyzers,
analyzer firmware updates.
The software enables readout of selected parameters and their visualization in real time. These parameters are measured independently from the registration saved on the memory card. The user can view:
charts of voltage and current progression (oscilloscope),
charts of voltage and current over time,
phasor diagram,
measurements of multiple parameters,
harmonics and harmonic powers (estimating the direction of harmonics),
interharmonics.
