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).
