Power quality analyzer
Description
PQM-711 power quality analyzer is an advanced product for wide type of measurements, analysis and recording of network parameters 50/60 Hz and the power quality diagnostic according to European standard EN 50160. PQM-711 is an innovative model with a wireless communication Wi-Fi , which allows for automatic pairing with the included tablet, with a large 10" touch screen. Tablet allows full operating of the analyzer, live data preview and the reading and analysis of data stored in the internal memory. With this solution, the PQM-711 is an unique device that combines the advantages of the analyzer with built-in display and typical portable analyzers (known as Black Boxes).With the tablet you can very fast checked the device under test. On the other hand, you can leave the analyzer module for multi-measurements as a typical logger without display. You can very fast diagnose the machine under test using the tablet. On the other hand, you can leave the analyzer module itself for many days measurement as a typical logger without display. PQM-711 has a transient registration with a maximum sampling rate of 10 MHz (rapid changes in voltage) and control signals. The minimum duration of the registered transient is 650 ns.
Analyzer is addressed to a wide range of users who need to control the power quality with a mobile device, it meets the IEC 61000 standards for the Class A. Compliance with the standard includes measurement uncertainty, measurement methods and time synchronization with a reference signal. In case of using analyzer indoor with poor GPS signal additional antenna with 10 meters cable can be used. After placing antenna outside the GPS signal will be easily traced and used for internal clock synchronization.
In practice, the analyzer may be used with all network types with rated voltage from 110 V to 760 V, directly or indirectly via transducers. It works in the following networks:
- It works in the following networks:
- one-phase,
- split-phase with N wire,
- three-phase Wye type, with and without N wire,
- three-phase delta type,
- with constant voltage.
Thanks to these features PQM-711 can be used in power industry and industrial maintenance services, as well as in companies leading network analysis services.
