    PD Cherepovets Electric Power Network the branch of IDGC of North-West, PJSC

    In the production activities, our production department uses the following devices manufactured by SKB EP, LLC:

    • PKV/M7 high-voltage circuit breaker analyzer (in operation since 2008);
    • PUV-regulator dedicated for controlling the drive of a high-voltage circuit breaker at low voltage (in operation since 2019);
    • MIKO-1 industrial microohmmeter (in operation since 2019).

    Above-mentioned devices are used for diagnostics of both Russian-manufactured high-voltage circuit breakers (VMT-110, MKP-110, VT-35, S-35, VK-10, VMP-10) and of foreign production (LTB-145).

    Being used these devices have proven themselves to be the best side. With the help of PKV/M7, it became possible to detect internal defects of the circuit breakers in a non-demountable mode. The functionality of the device is very simple and easy to use. The device allows you to control main characteristics of high-voltage circuit breakers. The main faults identified by PKV/M7 during repairs are the different timing of contact closures. When analyzing the speed characteristics, speed dips are detected that indicate the presence of jamming or mashing in the mechanism and that means that repair is required. Before this device was purchased, all the characteristics had to be taken with the demount of the circuit breaker, which led to an increase in the repair time.

    The device for controlling the drive of a high-voltage circuit breaker at a low voltage (PUV-regulator) was purchased for the needs of our division relatively recently. The presence of this device made it possible to check the operability of a high-voltage circuit breaker at low voltage, which is one of the standards for testing and measurements.

    Industrial microohmmeter MIKO-1 is also relatively new for our company, but it has proven itself only on the positive side.

    All the devices we use are mobile. One more advantage of MIKO-1 is the presence of autonomous power supply.

    We would also like to thank you for holding free webinars dedicated to the study of the devices manufactured by your company.

    I definitely recommend these devices for organizations that operate high-voltage equipment.

    VES Energo Partnership, LLP

    In August 2019, our company purchased MIKO-7 milliohmmeter for the needs of the electrotechnical laboratory. This device was purchased to replace the DC bridge R333.

    During the use, the device has proven itself on the positive side.

    The main advantage that was noted when working with MIKO-7 is the high measurement speed that significantly reduced the time required to check the resistance of the transformer windings.

    I would also like to mention the strong robust and shockproof case of MIKO-7 that allows you to transport the device without fear of damaging it.

    The only inconvenience is the lack of a built-in battery for the possibility of autonomous operation. As far as we know, this flaw is taken into account and corrected in the new modification of the device MIKO-7M(A).

    [Manufacturer note]: You are absolutely right. Modified milliohmmeter MIKO-7M(A) is equipped with a built-in battery. You can learn more about its characteristics on the corresponding page of our website.

    During the entire operation of the device, there were no failures in its operation.

    We look forward to further cooperation and recommend SKB EP as a reliable and competent partner.

    Altyntau Kokshetau, Ltd.

    Since 2017, we have been measuring resistance of the main circuits of high-voltage column and tank circuit breakers with the help of MIKO-21 microohmmeter.

    Advantages of the device: intuitive and easy-to-use interface, touch-screen color display, small dimensions and weight, a wide range of manually set values of the test current, the ability to transfer measurement results to the computer. MIKO-21 works both from the 230V network and from the built-in power supply. The complete set of the device assumes the possibility of choosing different test cable options.

    During the operation, there were no failures or malfunctions in the operation of the microohmmeter.

    Central Power Networks the branch of Yakutskenergo, PJSC

    The service of isolation, overvoltage protection and measurements of Central Power Networks of Yakutskenergo, PJSC currently uses 4 measurement devices manufactured by SKB EP, LLC:

    • MIKO-1 - 3 pcs.;
    • MIKO-9A - 1 pc.

    MIKO-1 device has been actively operated since 2012 to measure contact resistance of high-voltage circuit breakers, disconnectors, separators, and other electrical equipment of switchgears. The device is easy to use, has a small weight and dimensions. Due to the reliable contact and cable connections measurement accuracy of the data obtained is high. Furthermore, the device is equipped with a convenient bag. During operation, the device has proven itself as a simple, unpretentious to use, but quite an accurate device.

    MIKO-9A device has proven itself perfectly (it has been in operation since 2019) when working on measuring DC resistance of power and measurement transformers. Among the main advantages of the device, we would like to point out the following:

    • Possibility of simultaneous measurement by 3 phases;
    • Reliable contact and cable connections;
    • High accuracy and speed of the measurements;
    • The ability to compare the data obtained with the factory data directly during the measurement process;
    • Large battery capacity, choice of operation from mains or battery;
    • Compactness, light weight, easy-to-use interface.

    Devices manufactured by SKB EP, LLC have definitely proven themselves on the positive side, no malfunctions were found in their work. These devices can be recommended to the enterprises engaged in the repair, operation and diagnostics of high-voltage equipment.
