Application
The analyzer is directed to a very wide range of users, with particular reference
to the maintenance staff. Due to its mobility and autonomy, any problems occurring
in the supply networks can be diagnosed on the spot. The analyzer can
be used in virtually all kinds of networks with rated voltage from 54 V to 760 V
– directly or indirectly via transducers. PQM-707 can be used in the field of professional
power engineering, maintenance services in industrial plants, as well
as among those providing services focused on network analysis.
Displaying data
The analyzer is equipped with a readable colour touchscreen. Its 800 x 480 pixel
resolution provides both high comfort of interacting with the interface and
high readability of the measurement results. The included stylus allows you to
work with dielectric gloves.
Durable and practical casing
The casing has been designed to allow easy access to the touchscreen and
all measurement and communication sockets. Folding lid protects the display
from damages. Thanks to the IP51 protection degree, the device can be used
in difficult conditions – it is not afraid of dust or water splashes.
Capabilities
PQM-707 is an autonomous meter allowing versatile measurement, analysis,
and registration of energy network (DC and 50/60 Hz) parameters. All parameters
are measured I/A/W class S of the IEC 61000-4-30 standard guaranteeing
high accuracy of measurements. The 7-inch colour touchscreen – The largest
in this class of analyzers! – enables intuitive and ergonomic operation. Thanks
to the built-in lithium-ion battery, the analyzer allows for efficient work during
the measurement without the necessity of connecting an external AC adapter.

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.
The report can be generated according to EN 50160, IEEE 519,
NEC 220.87 and the standards of the following countries,
among others: Poland, Australia, Russia, Chile, Moldova, Ecuador.
The full list of standards can be found in the software.
