Compact wrist-wearable micro-ohmmeter MIKO-10 is designed for instant DC resistance measurements within the range 1 μΩ - 0.1 Ω.

MIKO-10 enables measurements at following objects:

  • High-voltage or auto circuit breakers;
  • Releasing, connecting or disconnecting switches, contactors and relays;
  • Bolted, welded and brazed joints of current leads and busbars;
  • Rail connections and wagon wheel pairs;
  • Electric motors, generators, compensators, and other objects. 

MIKO-10 is ahead of similar instruments represented in the market due to a number of functional and technical features.

MIKO-10 is applied in electric networks, power plants or substations, traction substations of electrified transport, as well as in industrial enterprises where 10 A test current is sufficient for measurements.

In turn, test current in similar instruments does not exceed 2 A, so that MIKO-10 (with test current up to 10 A and the weight of 0.5 kg) achieves leading positions among micro-ohmmeters of this class.

In case of obvious oxide film on the contacts more powerful micro-ohmmeters are recommended, such as MIKO-21 (test current up to 200 A) or MIKO-2.3 (test current up to 1000 A), as measurements using low currents in such instances can show higher values of resistance and, as a result, the contacts may be unjustifiably rejected.

Different measurement modes are implemented in the instrument:

AUTO: is intended for contact resistance measurement of HV circuit breakers w/o CT and any demountable or non-demountable connections with test current 10 A. The measurement starts automatically by the circuit closing;

SINGLE: is intended for contact resistance measurement of HV circuit breakers w/o CT and any demountable or non-demountable connections with test current 1 A or 10 A. The measurement starts by the User command;

BUILT-IN CT: is intended for contact resistance measurement of HV circuit breakers with CT with test current 10 A. The measurement starts by the User command.

MIKO-10 is a modern compact micro-ohmmeter that meets the latest user requirements.

The instrument has a number of important functions:

  • Auto thermal EMF balancing in the test circuit;
  • Auto power off, if the instrument is not used;
  • Circuit continuity test;
  • Auto measurement start against the test circuit continuity confirmation;
  • Sound alarm at the start and at the end of the measurement.

One battery charge is enough for at least 1,000 measurements at maximum current.

The instrument has an energy independent memory of up to 100 recordings that is sufficient for overall and complex test of the substation.

USB connection to the PC facilitates classification and storage of the measurement results and generation of the reports.

Special software developed by the manufacturer is used for data transfer from the instrument to the computer and for measurement results archiving.

The built-in battery of MIKO-10 makes the operation process fully self-contained. One battery charge is enough for more than 1,000 measurements at maximum current. Energy independent memory up to 100 recordings ensures a complex test of a substation.

MIKO-10 can justly be referred to portable instruments due to its light weight of 0.5 kg and small dimensions 165 × 100 × 60 mm.

The above peculiarities ensure complete autonomy of the instrument over the vast territory of substation or facility.

MIKO-10 is enclosed in an ergonomic case that can be placed on the arm and secured with fastening straps, with both hands free to simplify the measurement process.

Also, the instrument can be easily removed from the arm and fixed to a belt or your neck, or placed on any flat surface.

There are specially designed cables of different length and with different lugs for reliable connection to the measurement object.

Additional items to be purchased:

  • Kelvin double hand spike test cables. For instance, these cables can be used to test the resistance of busbars and terminal buses;
  • Kelvin clamp test cables;
  • Kelvin type test cable with probes and crocodile clips
  • Protective case;
  • Universal belts;
  • Wearproof tool bag.

High accuracy of results is ensured even for diagnostic in heavy weather conditions. MIKO-10 operation is guaranteed at a temperature range from -20°С to +55°С.

    Vorkutinskiye thermal power plants, LLC

    The electrical laboratory of Vorkutinskaya TPP-2 Vorkutinskiye TPP, LLC T Plus, PJSC has in its instrumental and technical base the following devices manufactured by SKB EP, LLC:

    • MIKO-1 micro-ohmmeter that is used since 2005;
    • MIKO-10 micro-ohmmeter that is used since 2017;
    • PKV/M5N high-voltage circuit breaker analyzer that is used since 2006 with an angular movement transducer DP21 and a linear movement transducer DP12;
    • PKV/M7 high-voltage circuit breaker analyzer with a PUV-regulator device that are used since 2018, with an angular movement transducer DP21 and a linear movement transducer DP12.

    With the help of micro-ohmmeters, electrical laboratory personnel measures DC resistance of contact connections, and PKV/M5N and PKV/M7 devices are actively used to measure the speed and time parameters of circuit breakers of 6, 35 and 110 kV voltage classes.

    Micro-ohmmeters are convenient to use due to their autonomy and mobility. PKV/M5N device, despite its long service life, is relevant during the diagnostic of high-voltage circuit breakers (due to the presence of linear and angular movement transducers in the complete set), but, due to moral aging and replacement with new analogues, the device cannot be supplemented with new components. The new PKV/M7 device is supplemented with all the necessary spare parts, is modern, mobile, accurate and, based on this, is more in demand by electrical laboratory specialists.

    As a result of the operation of devices manufactured by SKB EP, LLC by the personnel of Vorkutinskaya TPP-2, we can say about the reliability and high-quality operation of the above-mentioned devices and express a desire to continue interaction with specialists of SKB EP, LLC on technical and commercial issues.

    SKTB Granit, LLP

    Currently, in SKTB Granit LLP, we use MIKO-10 micro-ohmmeter manufactured by SKB EP LLC in the amount of 1 piece since 2019.

    With the help of MIKO-10, we mainly check the quality of the resistance of the contact groups of protective and functional grounding on newly installed equipment in accordance with the requirements of GOST.

    Before MIKO-10 purchase, we have been using F-415 micro-ohmmeter. The weight of this product is about 7-8 kg, which was a great inconvenience in operation. It is much more convenient to work with compact micro-meter MIKO-10 that can be easily fixed on the arm.

    In our work, we mostly often use the "Single" measurement mode. We do not check the high-voltage equipment with this device.

    With the help of MIKO-10, it is difficult to meet the requirements of GOST 17441-84 "Contact connections. Acceptance rules and test methods", as well as to check the functional grounding of the installed equipment, on the body of which there are no connectors. That is difficult to be performed as MIKO-10 is supplied in the standard complete set only with test cables with a crocodile type clamps.

    But for such measurements, a test cable with double hand spikes together with a test cable with a crocodile clip is more suitable.

    Here is our offer: to complete the device’s standard complete set with two types of test cables. We think that the price of a test cable with double hand spikes will be small.

    [Manufacturer note]: Standard complete set of MIKO-10 includes a cable that is most often used on various types of objects. Unfortunately, cables with double hand spikes are not used so often, so they are included to the additional complete set of the device and are available on request. For more information about the entire list of components, see the Complete set section on MIKO-10 page.

    The economic effect of using MIKO-10 micro-ohmmeter was not calculated, but the percentage of detecting low-quality compounds increased significantly.

    The device is excellent. We recommend other organizations to use it.

    United Techno Service, LLC

    Our laboratory, on the recommendation of your specialist, purchased a small-sized microohmmeter MIKO-10 manufactured by SKB EP, LLC. Using the instrument leaves a positive feeling. We especially want to highlight its compactness, ease of use and performance at low temperatures. Not every instrument can brag about it. The instrument case is assembled efficiently, there are no backlashes and creaks. The settings menu is intuitive, autonomy is good, accuracy and measurement speed are also at a high level. The insulation of the measuring cables ensures that they remain flexible even at low ambient temperatures.

    As for the minuses, the connectors stick and give a little inconvenience when plugging in or unplugging, it would be more convenient make connectors like "banana".

    [Manufacturer note]: The fastening implemented in MIKO-10 microohmmeter is designed for reliable fixation of test cables to the device that excludes circuit break and ensures tight contact of cables with device inputs, which cannot be guaranteed in the presence of "banana" type connectors.

    We also would like test cables with loaded needle-type contacts to be in paired with the instrument, not as additional equipment.

    [Manufacturer note]: Standard complete set of MIKO-10 microohmmeter includes only one test cable (item code: SKB042.04.00.000), since the functionality of this cable is sufficient for most measurements. In our opinion, it is a universal cable for making measurements with MIKO-10. Test cables with spring loaded needle-type contacts are purchased depending on the measurement object requirements where a standard cable cannot be used.

    Our laboratory recommends the MIKO-10 to purchase.
