Reviews

Nowadays the following instruments are operated in the electrotechnical laboratory of AtrauLocalCompany, LLP: MIKO-1 micro-ohmmeter produced in 2016 and MIKO-7MA milli-ohmmeter produced in 2020.

During the tests, the instruments showed their reliability, stability of operation, ease of use. When using the above mentioned instruments, the measurement time was reduced.

The use of MIKO-1 and MIKO-7MA instruments gave the greatest reduction in time during the measurements. When using an AC bridge, one resistance measurement of 35kV transformer winding lasted about 1.5 minutes. When using MIKO-1 or MIKO-7MA instruments, the time for one measurement was reduced to 30 seconds.

The laboratory of DMZ LLC has been using the MIKO-10 instrument for several years now. Basically, the device is used by us on products of our own manufacture (copper busbar, rod), in order to exclude the manufacture of inadequate quality products. I would especially emphasize the simplicity and convenience of instrument usage. Digital measurement characteristics eliminate the possibility of errors when reading. Light weight and compactness allow you to quickly move the instrument to any necessary location.

DMZ LLC expresses its gratitude to you for such a convenient device. We plan to continue cooperation with your organization and recommend your manufactured instruments for use.

Currently, one MIKO-7MA instrument is used in the electrotechnical laboratory of the power plant of JSC "Organica."

There have been no shortcomings or low-quality components of the instrument since October 2021.

The MIKO-7MA instrument is used for diagnostics of 10/0.4 kV power transformers, current and voltage transformers, electric motors, contacts, and contact connections of power circuits, and for measuring DC resistance.

With the help of MIKO-7MA, defects in the NLTC were detected, caused by the closing contacts high degree of oxidation in power transformers of 10/0.4 kV.

This instrument is used to measure electrical resistance to direct current of traction transformers of a railway rolling stock, high-voltage circuit breakers and disconnectors, electric motors of all capacities, any switching devices.

The use of MIKO-2.3 instrument has given the greatest reduction in time when measuring and increased the accuracy of obtained data. The digital display of the measurement result allows you to record test data more precisely. Low weight, small size, absence of movable and fragile parts in the instrument simplifies its use.

Currently, SPO Arctic, JSC uses three types of measuring instruments manufactured by SKB EP, LLC: low/high resistance meter MIKO-2.3, micro-ohmmeters MIKO-1, milli-ohmmeter MIKO-8 (six pieces in total). For more than 10 years, these measuring instruments have been operated at a manufacturing facility without complaints.

With the help of MIKO-2.3 and MIKO-8, the ohmic resistance of windings of DC and AC electric machines with a capacity of up to 500 kW is measured, as well as the ohmic resistance of rheostat stages. The measuring instruments are quite convenient and functional in operation. The presence of a built-in battery (MIKO-2.3) allows you to take measurements distantly. Light weight simplifies transportation (carrying).
