Energy survey of facilities, development of technical reports and recommendations for introduction of energy-saving technologies

  • Our company carries out integrated intra-day measurements of electrical energy quality. Measurements are made by G4420 Power Quality Analyser, manufactured by Elspec.

    Russian conformity certificate РОСС IL.AЮ05.В32699.

    Our expertise enables complete work sequence:

    • Economic efficiency calculation resulting from introduction of PFC units;
    • measurements of the quality of electrical energy in companies’ distribution networks, results are summarized in a report
    • process monitoring and assessment (monitoring) of electrical energy quality
    • project design for introduction of PFC units with reference to individual power consumption conditions
    • delivery, installation, commissioning of equipment

    During measurement internal memory of the complex with a maximum resolution of 39 µs, records all parameters of the electrical network:

    • linear voltages (current values, dips, overvoltages);
    • phase voltages (current values, dips, overvoltages);
    • phase currents;
    • cos φ per phase;
    • active power per phase (kW);
    • reactive power per phase (kVAr);
    • complete power per phase (kVA);
    • voltage and current harmonics up to the 256th harmonic component in all phases;
    • network frequency;
    • THD I% current curve distortion;
    • THD U% voltage curve distortion, etc.

    These studies are required for future installation of:

    • capacitor units for reactive power compensation;
    • determination of the required power (kVAr) for each power transformer;
    • selection of protective chokes for compensating capacitors;
    • selection of power harmonic filters. For the purpose of eliminating the effect of harmonics generated by non-linear consumers (UPS, frequency drives, resistance welding installations).
