The PQM-700 power quality analyzer is a high-tech product that allows universal measurement, analysis and recording of the parameters of 50/60 Hz electrical networks and the quality of electrical power in accordance with European regulations EN 50160 and the Regulation of the Minister of Economy of May 4, 2007 on the specific operating conditions of the electro-energy system. The analyzer fully complies with the requirements of EN 61000-4-30: 2011 class S.
The analyzer is equipped with 4 banana plug leads marked L1, L2, L3, N. The range of voltages measured by the four measurement channels is a maximum of ± 1150 V. This range can be increased using the additional external transformers. tensile.
The current is measured by four current inputs inserted into the short cables terminated with clamp plugs. The flexible clamps F-1 (A), F-2 (A), F-3 (A) with the nominal range of 3000 A can be connected to them (which only differ by the diameter of the coil) and the clamps rigid C-4 (1000 A AC range), C-5 (A) (1000 A AC / DC range), C-6 (A) (10 A AC range) and C-7 (A) (10 A AC range) 100 A AC). In addition, in case of currents, the nominal range can be changed by means of additional transformers, for example using the 1000: 5 transformer with the C-6 (A) clamp the current can be measured up to 1000 A.
The device has a standard 2GB removable memory card. The data on the card can be read using the USB connection or the external reader.
The registered parameters are divided into groups that can be included or excluded from the registry independently, allowing the rational use of space on the memory card. Unregistered parameters do not take up space, therefore the recording time of other parameters is considerably prolonged.
The PQM-700 analyzer has an internal power supply with a wide input voltage range 100 … 415 V AC (140 … 415 V DC) with independent banana plugs.
An important feature is its ability to work in unfavorable weather conditions, the analyzer can be installed directly on power poles. It ensures IP65 class tightness and the working temperature range is -20 ° C … + 55 ° C.
The internal lithium-ion battery ensures uninterrupted operation in the event of a loss of 5 hours of supply voltage.
5 LEDs and 2 Buttons are the user interface tool.
Using the PC software “Sonel Analysis” you can configure the measurement point, time intervals, parameters, and then download the measured data and generate the corresponding report.
Communication with the computer is possible with a USB connection that ensures the transmission speed of up to 921.6 kbit / s.
