    Urengoy branch of Gazprom Energo, LLC

    Since 2017 Electrotechnical laboratory of the Urengoy branch of Gazprom Energo, LLC has been operating MIKO-10 and MIKO-21 micro-ohmmeters and also MIKO-8M(A) milli-ohmmeter. These devices are used to measure the resistance of switching devices, power and measuring transformers, and electric motors.

    The advantages of the operated devices include small dimensions and weight, the presence of built-in power sources in MIKO-10 and MIKO-21 micro-ohmmeters, a simple and intuitive interface.

    [Manufacturer note]: MIKO-8M(A) milli-ohmmeter also has a built-in power supply. It can be supplied both without a battery: MIKO-8M version, and with it: MIKO-8MA version.

    During the operation, all devices have proven themselves on the good side, there are no malfunctions or failures. In comparison with the previous versions of measuring devices, MIKO-10, MIKO-21 and MIKO-8M(A) have become more efficient, which allows, in addition to the high accuracy of the measurements obtained, to reduce the work time due to the simpler assembly of the measurement circuit.

    Kaliningrad TPP-2 the branch of Inter RAO - Power Generation

    Since 2013, Kaliningrad TPP-2 the branch of Inter RAO - Power Generation JSC has been successfully operating PKV/M7 a high-voltage circuit breaker analyzer. This device is used by the personnel of the electrical department to measure the parameters of SF6 switching devices 110-330 kV.

    PKV/M7 device is very simple and easy to use. A simple and clear menu does not require special training or skills to work with it. The device itself is quite compact, easy to carry and transport to remote objects. PKV/M7 is suitable for carrying out measurements for all types of circuit breakers (SF6, oil, vacuum) and does not require additional remote units, which makes it very convenient to operate. The fact that one employee is able to complete all the work significantly reduces the labor costs for preparing and performing measurements. The device allows you to automatically measure and calculate the parameters of the tested equipment, and the use of the internal memory of the device simplifies and speeds up the process of filling out measurement reports and protocols. Also important is the presence of the extended range of supply voltages of the device that significantly reduces the time spent looking for a power source, especially at remote sites.

    During the entire operation of PKV/M7, no problems or malfunctions were detected with the device. Without a doubt, I would recommend using this device to other companies.

    Stankonia, LLP

    MIKO-7M milliohmmeter that we received in December, 2020 corresponds to the description and the declared technical parameters. With this device we check the windings of power and measurement transformers, electric motors, generators, circuit breaker contactors, busbars and other circuits.

    MIKO-7M is very convenient to be used and carried, as it has a protective case. The measurement settings menu is clear, the functionality of the device is more than convenient: there are user-friendly interface, automatic measurement mode selection, high speed and accuracy of measurements. Moreover, test cables remain flexible at subzero temperatures. MIKO-7M milliohmmeter fully meets our needs and requirements.

    Khabarovsk repair and installation company, JSC

    Since 2010, Khabarovsk repair and installation company, JSC has been successfully using in its professional activities one PKV/M7 high-voltage circuit breaker analyzer and one PUV-10 control panel for the drive of the high-voltage circuit breaker.

    Basically, PKV/M7 and PUV-10 are used to measure the parameters of high-voltage circuit breakers of 6 (10) kV voltage classes, less often of 35 kV voltage class. But PKV/M7 has also been repeatedly used to measure time parameters of high-voltage circuit breakers of 110 kV and 220 kV voltage classes of foreign and Russian production.

    The advantages of PKV/M7 and PUV-10 are: reliability because for 10 years of operation, the devices have proven themselves in a good way; simplicity and ease of use; low weight and dimensions of the devices; the design of PKV/M7 in a robust case that is very important during device transportation and field operation.

    Taking into account our experience, we would like to recommend SKB EP devices for high-voltage equipment diagnostics.

    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.
