    Spectrum, LLC

    MIKO-7M instrument is in operation in the electrotechnical laboratory of Spectrum LLC.

    This instrument is used when measuring the DC resistance of windings (transformers, arc-extinguishing reactors), the esistances of circuit breakers both newly installed and for diagnostic purposes after emergency situations.

    During operation the instrument proved to be excellent. It has an intuitive interface, high-quality clamps and quick measurement. The robust housing allows you to count on a long life of the instrument.

    The use of MIKO-7M made it possible to abandon the measurement using a DC direct current, which has simplified the measurement procedure and has reduced the time to receive data.

    Using the example of MIKO-7M operation, we can conclude about the high quality of the instruments of SKB EP, LLC and recommend them for use.

    At this time, at our enterprise, specialists use the micromilliocilo-ohmmeter MIKO-2.3 instrument for your products, check power transformers 6/0.4 kV, switching devices 6 kV, 0.4 kV and explosion-proof electric motors 0.4 kV.

    The use of MIKO-2.3 instrument simplifies and greatly speeds up the process of checking electrical equipment, unlike other analogues of the instrument.

    During the year of operation, the instrument revealed numerous defects in electrical equipment, such as heating of the contacts of the switching device, damage to the windings of intrinsically safe electric motors, etc.

    After operation of MIKO-2.3 we confidently recommend to use it. TOO "Gas Processing Company" expresses its gratitude to SKB EP for the quality instrument and wishes you success in your activities!

    Last month at least in 7 VMPE-10 out of 15 circuit breakers which were serviced according to the operations management plan, contacts with deviation of parameters from the norm were detected. The detection of these defects at an early stage allowed orginize preventive maintanance and, as a result, to prevent an emergency failure of high-voltage substation equipment.

    The instrument is quite convenient in operation. The following advantages can be emphazised: samll size, portability, reliability, ease of use and high measurement accuracy. The presence of a built-in battery allows you to operate the instrument for a long time without mains power.

    The small instrument MIKO-2,3 is convenient for measurements due to its light weight and dimensions, especially when working on circuit breakers U-110 and MKP-110. When placing the instrument directly on bushings of the circuit breaker, one person is involved in this process. Reliable wire fasteners are attached to circuit breaker bushings. High measurement accuracy, the use of two different power supply systems of the instrument (mains and battery) expand the use of the device.

    PKV/M7 has shown itself as a reliable, affordable and fairly accurate instrument.

    The use of PKV/M7 instrument halves the time for taking parameters of a circuit breaker, because all measurements are performed in one cycle, which allows you to quickly assess the equipment technical condition.

    PKV/M7 instrument allows you to take a variety of parameters (speed, time) of circuit breakers and detect defects of equipment without disassembly, to plot graphs based on the parameters. These are the pluses of this instrument.

    The instrument operation requires care and accuracy while making measurement methods at the early stage. The skills of systematization of measurements appear and the speed of testing increases after regular use.

    The measurement method is simple and clear. A good function of the instrument is the ability to plot graphs of circuit breaker closing and generating data on a personal computer.

    The following defects were identified when testing 6kV oil-blast circuit breakers: incorrect operation of a circuit breaker buffer, non-simultaneous closing of phases, wear of insulating rods.
