    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.

    Kuban MEN the branch of FGC UES, PJSC

    I would like to inform you that in the branch of FGC UES, PJSC - Kuban CMEN uses MIKO-1, MIKO-2.3, MIKO-10, and MIKO-21 microohmmeters.

    During the operation, MIKO-group devices have proven themselves to be the best in terms of reliability, ease of use and accuracy of the results obtained on the state of the switching equipment (circuit breakers, disconnectors). The devices are also good at resistance measurement of pressed connections, resistance measurement of transformer windings. The devices are easy to transport (there is a special carrying bag), they are convenient to use due to the small size and built-in power supply.

    Among the disadvantages there is the lack of crocodile clips (or clamps) in the standard complete set for connecting to a large-section busbar (rigid busbar, hollow wires).

    [Manufacturer note]: Device complete set includes those cables that are most often used on various types of objects. Cables that help to measure resistance on large-section busbars are unfortunately used not as often, so they are included to the additional complete set of the devices and are available by request.

    Devices manufactured by SKB EP, LLC gave a good account of themselves and can be recommended to the companies performing adjustment or repair works, testings and measurements.

    Eastern Electrical Grids the branch of IPGC, OJSC

    In the Eastern Electrical Grids the branch of IPGC, OJSC we have been using the following devices manufactured by SKB EP, LLC:

    • PKV/M7 circuit breaker analyzer (since 2012);
    • MIKO-1 microohmmeter (since 2014);
    • MIKO-2.3 micromillikiloohmmeter (since 2019).

    PKV/M7 circuit breaker analyzer proved to be reliable, there was not a single case of failure. The device allows to measure several parameters in one measurement cycle, which significantly reduces the total time spent on assessment of the circuit breaker technical condition. The ability to use local and remote start expands the application area of this instrument.

    MIKO-1 microohmmeter has established itself as a simple, unpretentious in use, but quite accurate device. It is compact, and its test cables are flexible, therefore the work might be done even at low temperatures.

    MIKO-2.3 device is easy to use due to its small size. The device is equipped with a convenient and useful carrying bag in that you can put all the accessories and test cables. Additionally, we purchased test cables of different lengths and different other accessories that made it easier to work with the device on various equipment. During the use of the device, no failures in its operation were detected.

    We express our gratitude to SKB EP, LLC for the production of high-quality and reliable devices and we recommend the use of these devices to companies of various activity types.

    Condensate Stabilization Plant named after V.S. Chernomyrdin (Surgut CSP) the branch of Gazprom Pererabotka, LLC

    Our plant has been using MIKO-8 milliohmmeter since 2016. The device is built into a good strong case that is convenient for transportation. During the time of use, with the help of MIKO-8 were diagnosed more than 100 units of electrical equipment (transformers, electric motors of various capacities and other equipment). One of the main advantages for our staff was the ability of automatic recalculations of deviations with indication of parameters and their saving into the device memory. The second advantage is the possibility of further processing of measurement results on a PC using specialized software. Also, among the advantages we can highlight the measurement speed, intuitive operation of the device, and its small dimensions.

    Among the disadvantages, we note the use of non-standard connectors on the test cables and the inability to use third-party cables, the lack of auto power selection of the device.

    [Manufacturer note]: Cable connectors that are implemented in our devices actually involve the use of the cables only of our production. Thereby we guarantee the reliability of the devices that you use, and we are responsible for the results that you get during measurement process. Unfortunately, when using third-party cables, we cannot guarantee the correctness of the data obtained.
    The possibility of auto power selection is implemented in the upgraded versions of our milliohmmeters, more information about their characteristics can be found via the link. In addition, in modern milliohmmeters, the power can be set both automatically and manually.

    MIKO-8 copes well with the assigned tasks. We can recommend it to other companies.
