• About Us

    Since 1991 Mars-Energo designs and manufactures highly specialized instruments and systems for testing and calibration of electrical energy meters and instrument transformers. Our solutions are widely used by meter and transformer test laboratories, utilities, industries, meter and transformer manufacturers.
  • Cooperation

    In cooperation with the D.I. Mendeleyev Institute for Metrology (VNIIM) and All-Russian Research Institute of Metrological Service (VNIIMS), our company is working on the development of reference instruments for accuracy testing of measurement equipment within digital substations and smart grids.

    Another area of our collaboration covers development of the system of national reference standards.

  • Metrological Laboratory

    Mars-Energo has its own accredited metrological laboratory where, among the equipment at our disposal, there are the Power Calibration system (expanded uncertainty of AC active/reactive power measurements = ±0.004%) and the High-Voltage Reference System of voltage scaling factor. All measurement instruments manufactured at our factory are tested here.
