Features

Power from the measured network.
Designed for use in virtually all network types from 64 V to 760 V directly, with particular emphasis on measurements at low voltage poles, due to the ease of installation.
Independent power supply makes it particularly suitable for measurements behind voltage transformers. It can also be used for measurements in DC voltage systems.
Remote configuration and data transfer (GPRS) in real time using the built-in GSM modem.
Anti-theft function – text message notification in case of position change – built-in GPS receiver.
Real time clock synchronized using GPS protocol.

Capabilities

As a standard, the analyzers are equipped with an 8 GB memory card, which allows you to collect over 4500 parameters simultaneously – at intervals of up to 200 ms. In addition to checking the power quality according to standards and ordinances, it allows you to create a detailed situation picture in terms of operation and possible disturbance. However, nothing stands in the way to make this image even clearer – the manufacturer can expand the memory to 32 GB (optional).

PQM-702 and PQM-703 record control signals in power networks. In addition, the PQM-703 model is equipped with a transient recorder with voltage range up to ±8000 V and a maximum sampling frequency of 10 MHz.

The built-in GPS receiver ensures real time clock accuracy, and the integrated GSM modem facilitates remote analyzer operation.

Displaying data

The colorful, backlit 3.5” LCD screen with a resolution of 320 x 240 pixels presents basic parameters of the tested network, such as voltage, current and power – everything in a clear and transparent way. Information about the device configuration as well as messages and warnings about the operation status or emergency conditions are available. In addition, the user can check the phasor diagram to check the network connection.

The analyzers can be remotely controlled. The user can set up the meter, check measured parameters in real time and download registered data. The remote connection is made in two ways: either by the OR-1 radio receiver or using the built-in GSM modem.

OR-1 radio transmission operates over a distance of up to 50 m. GSM transmission gives an incomparably greater range: after inserting any SIM card with a static IP number into the analyzer, you can access it from anywhere in the world.

Application

The analyzers are addressed to users who need to control power quality using a mobile device that meets the requirements of the IEC 61000 class A standard for analyzers. PQM-702 and PQM-703 fully satisfy the functional needs of power quality analysis and interference diagnostics in power networks. They are used in the field of professional energy and maintenance services in industrial plants, as well as among independent power quality specialists.
