    The branch of FGC UES, PJSC Novgorod PMES

    In response to a request No 30112 dated 09.06.21, I inform you that a circuit breaker analyzer PKV/U3.1 (serial number 14) is operated in the branch of FGC UES, PJSC Novgorod PMES.

    During the time of usage I point out a positive instrument operation and the ease of use while diagnosing circuit breakers of types: U-110, VMT-110, VV-330B There is no "20-channel pole cable" of the required length in the standard complete instrument set for VV-330B diagnostic.

    PKV/U3.1 instrument copes well with measuring speed and time circuit breaker actuation, carrying out simultaneous taking characteristics in three phases. A wide range of attachment devices helps to install transducers on different circuit breakers.

    The commissioning work time significantly reduces due to ability to make measurements (triggering) of a circuit breaker and obtaining results in specialized software, which allows you to analyze, predict and eliminate various defects directly from the place of work.

    We recommend this instrument to companies operating high-voltage circuit breakers, as well as electric laboratories diagnosing circuit breakers.

    [Manufacturer note]:For connection to the contacts of air-blast high-voltage circuit breakers a 20-channel pole cable ( with a length 1.2m is supplied in a standard complete set. If you need a cable of a different length, please contact us, we will make it to order.

    Our electrical equipment commissioning team has been operating MIKO-21 micro-ohmmeters in the amount of 3 pieces since 2020. These instruments are used to measure resistance of automatic circuit breakers contact connections the contact resistance of bolted connections and welded joints.

    The instrument MIKO-21 has a small weight and is assembled in a convenient, durable case. The instrument menu is simple and user-friendly. When operating 200 A Kelvin double hand spike test cables and 200 A Kelvin С-clamp test cables has been additionally purchased, which expanded the possibilities for instrument connection.

    The instrument MIKO-21 has shown itself advantage and can be recommended to organizations to perform tests, measurements, commissioning and repair of electrical equipment.

    Primorsky Aquarium

    Currently, the instrument MIKO-1 is in operation in electrotechnical laboratory of Primorsky Aquarium.

    This instrument is used in operational tests of high-voltage circuit breakers, disconnecting switches, circuits of the main contactors in refrigeration units.

    During the operation of MIKO-1 no spoilage was revealed. The instrument is convenient to use due to its small size, light weight, intuitively clear interface and reliability in design.

    A digital display simplifies the process of recording the received data and saves time. The circuits of the main contactors required early maintenance were identified and interruptions in the refrigeration units operation were eliminated due to the instrument.

    Based on the above, we can centainly recommend MIKO-1 for purchase in order to carry out routine tests and diagnostic of power equipment.

    The instrument MIKO-9A is operated at the moment in the electrical measurement laboratory of PremierStroyDesign, JSC.

    The full package of documents included in the instrument standard complete set allowed us to master the instrument functionality without problems. It is also worth mentioning that we contacted the company SKB EP, LLC when had faced the instrument activation and specialists immediately got in touch and solved all issues. We express a special gratitude for that.

    During the operation of MIKO-9A instrument since November 2020, no serious drawbacks and low-quality components were identified, which would make impossible the use of the instrument or would prevent any works.

    The main advantages of MIKO-9A instrument are compact size, the ease of transportation. For field work it is the quickness of equipment deployment (workplace). An important thing is the ease of control of the instrument and the digital indication of measurement result. The instrument is equipped with a built-in battery, which allows us to make measurements even in field conditions.

    The operation of MIKO-9A has significantly reduced the time for diagnostic of the following equipment: power transformers 10/0.4 kV 35/10 kV, power equipment of substations 10/0.4 kV 35/10 kV, busbar bridges 0.4 kV 10kV 35 kV, electric motors of all capacities and many other equipment, as the range of instrument functions is large.

    PremierStroyDesign, JSC thanks SKB EP, LLC for the manufacture of high-quality instruments and for the interest shown in the operation of its products. We hope for new developments and equipment which will interest the specialists of electrical measurement laboratory.

    PJSC "Second Generating Company of the Electric Power Wholesale Market"

    Currently, a high-voltage circuit breaker analyzer PKV/U3.1 is operated in the electrical laboratory of an electric shop in the branch of OGK-2, PJSC Serovskaya GRES.

    This instrument has been used since 2014 for high-voltage circuit breaker diagnostic, in particular: VVN-220 air-blast circuit breakers, VGT-110 SF6 circuit breakers, SION 3AE 1185-1 vacuum circuit breakers. The instrument has proved its reliability and multifunctionality during operation as it is able to assess the state of high-voltage circuit breakers of all types and has lots of various adapters and devices for diagnostic.

    When diagnosing VVN-220 circuit breaker with PKV/U3.1 there were found mismatches in nominal values of the time characteristics in circuit breakers actuation.

    PKV/U3.1 instrument helped to reduce time for diagnostic of high-voltage circuit breakaers, because it is possible to see the measured values in digital values as well as in a view of oscillogram immediately after the measurement.

    According to the results of the instrument operation for more than 7 years, this instrument is recommended for diagnostic of high-voltage circuit breakers.
