    Zavod im. S.M. Kirova, JSC

    The instrument MIKO-10 has been in operation in the electrotechnical laboratory of Zavod im. S.M. Kirova, JSC since 2017.

    We use this instrument for contact resistances measurements of high-voltage and low-voltage equipment at our enterprise.

    During the operation, the MIKO-10 has proven its reliability, ease of use, accuracy and quickness of measurements.

    The main advantage of the instrument is its functional ability to archive measurement data made, which significantly reduces the time of regulated work when measuring contact resistances of various equipment.

    There has been no serious disadvantages and minuses in the instrument and its functionality.

    From the moment we used the instrument, ETL specialists diagnosed dozens of malfunctions in the electrical equipment earthing systems, that was a dangerous factor regarding electrical safety. In particular, different defects of the equipment produced by our company were revealed at an early assembly stage.

    Based on the above mentioned and with great confidence, we can recommend instruments of SKB EP to various enterprises.

    EnergoSK, LLC

    The company EnergoSK, LLC, the department of the electrotechnical laboratory, currently performs tests and measurements at the Amur TPP.

    The applied instruments of your production: MIKO-1 micro-ohmmeter, MIKO-8 milli-ohmmeter.

    We have been using these instruments since 2011, there are no complaints.

    MIKO-1 is used for measuring the contact resistances of high-voltage circuit breakers, busbars, etc. The instrument works reliably, quickly with high measurement accuracy.

    MIKO-8 is used in measuring the resistances of windings in power transformers, current and voltage transformers, electric motors, generator stators and rotors. The instrument operates at a high measurement speed that greatly saves measurement time.

    The instruments have been just tested for all the years of operation. There have been no breakdowns.

    I recommend you using these instruments, as I have been used them myself for many years!

    Kamchatskenergo, PJSC

    Kamchatskenergo, PJSC has been operating instruments manufactured by SKB EP, LLC: PKV/M5, PKV/M7, MIKO-1, MIKO-2.3, MIKO-21 since 2005.

    The advantages of PKV/M5, PKV/ M7 are: the ease of operation, an ability to determine a necessary number of controlled parameters with the required accuracy, the identification of defects without disassembling a circuit breaker, an opportunity to view the results of measurements and graphs of dynamic characteristics, a choice between local and remote triggering and usage of instruments on almost all types of switching equipment. I would also like to note the compact size of the instruments and the presence of a protected case, which is important when transporting and working at a substation.

    MIKO-1, MIKO-2.3, MIKO-21 instruments are used to measure the transient resistance of contact connections of switching devices with a voltage of 6-10-35-110-220 kV. The advantages of these instruments include light weight and dimensions, a durable case, sufficient current for carrying out necessary measurements, autonomous power supply (MIKO-1), the ease of use.

    Basing on our own operational experience, Kamchatskenergo, PJSC recommends these instruments to all energy organizations and enterprises.

    Primorskaya GRES, LLC

    The electrical laboratory department of Primorskaya GRES, LLC has been used milli-ohmmeter MIKO-9A for the electrical equipment diagnostic since 2021.

    With a help of the instrument we measure the ohmic resistance of windings in transformers and autotransformers with a voltage up to 500 kV and a power up to 250,000 kVA, electric motors of various power with a voltage up to 6 kV. Moreover, we demagnetize the magnetic system of transformers, measure the transient resistance of contacts and bolted joints.

    The instrument is convenient due to its low weight and small size. A manipulating rod with special cables was purchased together with the instrument. In many cases, the use of the manipulating rod allows you to get rid of an autolift.

    The managers of Primorskaya GRES, LLC thanks SKB EP, LLC for manufacturing the necessary instrument for enterprise and hopes for the emergence of new developments. We recommend to other companies showing interest in the instruments produced by your company.

    ENGINEERING CONSTRUCTION SERVICE, LLC

    Currently, two PKV/M7 instruments have been operated since 2019 in the electrical department of ENGINEERING CONSTRUCTION SERVICE, LLC, in Bratsk branch. Oil circuit breakers MG-10, MG-110, MG-20, MGU-020 are analyzed by these SKB EP`s instruments. The instruments are quite convenient to use, easy to transport and carry in hands, also they are compact and have a relatively low weight. It is possible to accurately determine circuit breaker time and speed characteristics of closing and opening, pressing and moving parts travel. A defect while closing MG-110 has revealed by PKV/M7 (speed change, braking). The usage of PKV/M7 has great advantages in comparison with old methods of circuit breakers diagnostic. We can confidently recommend using of PKV/M7 instrument to other organizations for electrical equipment diagnostic. It is worth noticing "TRADE-IN" promotion that can provide 15-20% discount for new instruments.
