Power Quality Analyzer | PQM-707
Price range: R52,780.00 through R68,685.00 ex vat

Power Quality Analyzer - Overview

This Power Quality Analyzer allows for versatile measurement, analysis, and registration of energy network parameters DC and 50/60Hz. This includes measuring the quality of electric energy in accordance with the European standard EN 50160. To Guarantee accuracy, all parameters are measured with Class S according to the IEC 61000-4-30 STANDARD.

This is the largest in this class of power quality analyzers and has a 7-inch colour touch screen which enables intuitive and ergonomic operation. Thanks to the built-in lithium-ion battery, the analyzer allows for work during the measurement without the necessity of connecting an external AC adapter.

The analyzer can be used directly, or indirectly via transformers in virtually all kinds of networks with rated voltage from 54V to 760V. Due to its mobility and autonomy, any problems occurring in the supply networks can be diagnosed on the spot. With a safety rating of CAT IV 600V, the Power quality analyzer provides peace of mind during everyday use. The PQM-707 can therefore be used in the field of professional power engineering, maintenance services in industrial plants, as well as network analysis.

Electrical Installation Meter with Power Analyzer | MPI-540

Electrical Installation Meter - Overview

The MPI-540 meter is designed for checking the safety of industrial and domestic electrical installations. The user has the option to register the parameters of electrical networks located at these facilities. This allows for the measurement of the parameters for protection against electric shock using a single universal device while verifying the quality of electricity. The Auto mode allows significant automation of measurements of the meter and makes it possible to test the functioning of residual current circuit breakers, as well as in pre-programmed measuring sequences, which can be extended with their own sequences. Automatic measurement of insulation resistance of 3-, 4- and 5-wire conductors is possible by using an additional AUTO ISO-1000C adapter.

Power Quality Analyzer PQM-703

Power Quality Analyzer - Overview

Power Quality Analyzers PQM-703 include all features of the PQM 702 but with extra functionality: mains signalling up to 3000 Hz, Transients up to ±6000 V, and minimal transient capturing time of 650 ns. This technically advanced product allows for comprehensive measurements of the quality of electricity, analysis and recording of power network parameters for frequencies 50/60 Hz, all in accordance with the European Standard EN 50160. Analyzers are fully compliant with the requirements of IEC 61000-4-30:2015, Class A.

The device is equipped with five voltage measurement inputs installed as cables terminated with banana plugs marked as L1/A, L2/B, L3/C, N and PE (ground). The voltages measured by four measurement channels are up to ±1500V (the device has two voltage sub-ranges). This range may be increased by using additional external voltage transformers. Current is measured using four inputs installed on short cables terminated with probe terminals. The terminals may be connected to the following probe types: flexible claps (marked as F-1(A), F-2(A), F-3(A)) with nominal rating up to 3000 A (differing from others only by coil diameter); clamps F-1A6, F-2A6, F-3A6 with a nominal range up to 6000 A and hard probes marked as C-4 (range up to 1000 A AC), C-5(A) (up to 1000 A AC/DC), C-6(A) (up to 10 A AC) and C-7(A) (up to 100 A AC). The values of nominal measured currents may be changed by using additional transducers – for example, using a transducer of 1000:5 ratio, the user may select C-6(A) probes to measure currents up to 1000 A
