Reviews

MIKO-7 manufactured by SKB EP, LLC has been operated in the electrical laboratory of Altair, LLC since 2012.

The instrument is used for commissioning works on transformers from 6 to 330 kV. We have to travel all over the country with instruments, because we are an installation and checkout organization.

There were no problems with damage of the instrument during transportation due to shockproof materials and compact size of MIKO-7.

This instrument has an ability to get 12V DC supply that is convenient while working in field conditions. We also have installed an advanced software to bring the measured resistance to the set temperature, through which we can quickly analyze the obtained measurement data.

MIKO-7 comes with its own standard wires with a separate cable for extension. This is very convenient when it is necessary to work on transformers of different sizes.

Moreover, the instrument provides a continuous measurement function for transformers with OLTCs and indicates the end of measurement process. This function significantly speeds up all measurements.

Having had an experience in instruments operation since 2012, Altair, LLC thanks SKB EP, LLC for the manufacture of high-quality products and for the expressed interest in the operating experience of using their instruments.

Currently two instruments are operated by the Electrical repair production of Severstal, PJSC: HV circuit breaker analyzers PKV/U3.0 and PKV/M7. According to practical evaluation, PKV/M7 is more convenient to operate than PKV/U3.0.

These instruments we use for high-voltage circuit breakers from 6 to 220 kV.

As for convenient functions, we need to mention the possibility of measuring angular movement and converting to linear. For example, speaking about one of the last cases, an increased contact time difference between the phases of VGBU-220 HV circuit breaker was revealed.

Economic effect calculations of using these instruments have not been carried out by our company.

Taking into account the operating experience of PKV/M7, we can definitely recommend it for use.

In 2020 our company purchased HV circuit breaker analyzer PKV/M7 produced by SKB EP (Irkutsk). The delivery of the instrument was carried out on time and in full compliance with contractual obligations. It was organized by the official sales representative in Belarus, NPP Belenergokip, LLC.

During operation, the instrument is used to diagnose HV circuit breakers up to 6-10 kV such as VV/TEL, RiM-VV, etc. The user-friendly interface as well as the wide functionality of PKV/M7 allows you to conduct a full range of diagnostic work quickly and effectively and identify equipment malfunctions at early stages.

We can notice the simplicity and reliability of the instrument, there are no facts of its incorrect operation, technical and software malfunctions. NPP Belenergokip, LLC specialists has been providing promptly the qualified support concerning supply and technical operation issues of above mentioned instruments.

In 2018 Krasnoyarsk enterprise of the main power networks got a high-voltage circuit breaker analyzer.PKV/M7.

The instrument has been defined as reliable, accurate in readings and easy-to-use during operations. We would like to stress the optimization of measurements. With a help of PKV/M7 specialists can monitor a large number of technical characteristics of HV circuit breakers. It is possible to download data to a personal computer, that simplifies and reduces the time for equipment diagnostics.

Due to usage of PKV/M7 we were able to identify and eliminate minor malfunctions independently and without the involvement of third-party organizations. That fact definitely had a positive effect on diagnostic cost saving.

MIKO-7M(A) was received by Shakhtinskteploenergo in April 2021. This milli-ohmmeter corresponds with the description and technical characteristics. We use the instrument to check windings of power and measuring transformers, busbars and other circuit. MIKO-7M(A) is very convenient to use, it also has a case. The settings menu is clear, the functionality is suitable. The milli-ohmmeter has user-friendly interface, automatic measurement selection, high speed and accuracy of measurements. Futhermore, test cables remain flexible even in conditions of subzero temperatures. The instrument fully meets our needs.
