Testimonials about Milliohmmeter MIKO-8
MegionEnergoNeft, LLC

In May, 2018 MegionEnergoNeft, LLC took milliohmmeter MIKO-8 for a trial operation. The instrument was used for measuring winding resistance of oil and oil-immersed transformers 0.4-110 kV of different types and brands at the electrical equipment repair facility during the transformer repairs and at transformer substations for routine test of the equipment under MegionEnergoNeft, LLC maintenance.

The following advantages of the instrument have been pointed out: small size, portable case convenient for transportation and operation, user friendly menu, built-in archive helping to speed up the measurement, simplify data processing, and perform automatic recalculation of the data received. The measurements were carried out in a short time which significantly shortened testing period compared to the alternative instruments of competitive brands.

Possibility to run measurements of power transformers winding resistance without switching the tested objects off shortens the testing time. The information is reflected in a big contrast display which allows reading the results without any difficulty. No defects or disadvantages have been found out during the trial operation. The instrument worked without any complaints.

We would suggest providing additional portable battery with built-in charger and a plug for field operations [Manufacturer's comment: Production of the device MIKO-8 is discontinued. A new version of MIKO-8M with be delivered to the warehouse in the III quarter of 2018. Orders are accepted. Comparison of the first version of the device and its modification is at Reference].

According to the results of the testing operation we conclude that the instrument meets the declared characteristics and exceeds world known brands in the majority of technical characteristics.

Testimonials about Milliohmmeter MIKO-7 with advance software, Milliohmmeter MIKO-7 with basic software

OKTYABR’, FSUE PA have been using milliohmmeter MIKO-7 for 1 year. We used the instrument to measure transient resistance of the contact areas of the grounding of the produced items.

The instrument is very easy to use. It is possible to operate the instrument from a computer and save the results.

We also faced a disadvantage: it is inconvenient to carry out the measurements on the contact areas with size less than 20x20mm (there is no repeatability of measurements, and measurement error is quite large) [Manufacturer's comment: the main purpose of the milliometer MIKO-7 is to measure the inductive resistance, so we recommend to use our microohmmeters for the works described above].

This instrument can be recommended for electrical maintenance of equipment such as tests for grounding of equipment, transient resistance, contacts of connectors and transition pads [Manufacturer's comment: for these works we also recommend our microohmmeters].

Testimonials about PKR-2

PKR-2 analyzer for diagnosis of transformer OLTC was procured by our company in 2014. Measurements were started in 2015. Measurements were performed on 110kV transformers with OLTS of РНТ-13, РНТ-20, РС-3, РС-4, and РС-9 types.

The instrument is easy to use, it has many useful functions. The  PKR-2 allowed identification of the following problems of the OLTC operation:

  • Wear of arch extinguishing contacts;
  • Resistors damage;
  • Unacceptable travels in the shaft fixing nodes;
  • Shaft shifts;
  • Incorrect connection of taps. 

Measurements using PKR-2 were two or three times faster than those by conventional methods. The instrument is rather convenient in operation.

The analyzer can be recommended to other companies for use.

In 2015 Siemens Company purchased MIKO-7 instrument for electric resistance measurement. It is still successfully employed by our specialists.  This instrument allows control of drive motor winding parameters and performance of different types of diagnosis of ES1 Lastochka fast-speed electric trains.

Based on the experience of MIKO-7 operation we should state that this instrument is easy to operate, has a simple and understandable interface.  Its main merit, in our opinion, is the function of automatic selection of resistance range.

The instrument can be powered both from the mains and from the car battery, which is its another merit.  However, I would recommend to furnish an in-built battery as it is not always convenient to operate the instrument from an external power source.
[Manufacturer’s comment: Subsequent versions of MIKO instruments will be furnished with an in-built battery].
