Capabilities

PQM-707 is a stand-alone meter that enables versatile measurements, analysis, and recording of power grid parameters (DC and 50/60 Hz). All parameters are measured according to Class S according to IEC 61000-4-30, which guarantees high accuracy of measurements. The 7-inch color touch screen – the largest in this class of analyzers! – Allows intuitive and ergonomic operation. Thanks to the built-in lithium battery, the analyzer enables efficient work during measurement without the need to connect an external AC adapter.

Easy to read

The analyzer is equipped with a readable color touch screen that, due to its resolution of 800 × 480 pixels, provides high comfort when interacting with the equipment and high readability of the measured results. The included pen allows you to work with dielectric gloves.

Applications

The analyzer is aimed at a wide range of users, with particular reference to maintenance personnel. Due to their mobility and autonomy, any problems that arise in the supply networks can be diagnosed on the spot. The analyzer can be used in virtually all types of networks with a voltage rating of 54 V to 760 V directly or indirectly via transformers. The PQM-707 can be used in the professional field of electric power, maintenance service in industrial plants, as well as by those who provide services focused on network analysis.

Practical and durable housing

The PQM-707's housing has been designed to allow easy access to the touchscreen, all measurement and communication sockets. The folding lid protects the screen from damage. Thanks to the IP51 degree of protection, the device can be used in difficult conditions – it is not afraid of dust or splashing water.

SONEL ANALYSIS

The Sonel Analysis program is an essential application for working with PQM analyzers. Depending on the coupling instrument used, the program allows:

• The analyzer configuration,
• Reading data from the analyzer,
• The display of network parameters in real time (with the possibility of reading via a GSM modem),
• Clearing data in the parser,
• The presentation of data in table form,
• The presentation of data in the form of diagrams,
• Data analysis and reporting in accordance with IEC 50160 and other user-defined reference conditions — also for micro PV installations up to 50 kW, with division for the 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),
• The independent service of several analyzers,
• Updating to new versions (through the program or through the website).

The program allows the reading of the selected parameters and their graphical presentation in real time. These parameters are measured independently of the record stored on the memory card. The user can see:

• Diagram of voltage and current paths (oscilloscope),
• Voltage and current diagrams,
• Phasor diagram,
• Measurement of various parameters,
• Harmonics and harmonic powers (estimation of harmonic directionality),
• Interharmonics.
