Presentation in the city of Osh, Kyrgyz Republic

Last week SKB EP organized a presentation along with the Power Engineering Institute of Advanced Training from St. Petersburg. The event was attended by the engineers, experts and electrical fitters of the Osh High-voltage Electric Grid. This company is a structural subdivision of the National Electric Network of Kyrgyzstan, OJSC.

SKB EP specialist made a report on how to run diagnostics and control of high-voltage equipment. The report included the following:

  • Resistance measurement in inductive and non-inductive circuits:
  • Theory basics of transient contact resistance. Features of resistance measurement in different circuits of electrical equipment.
  • Review of SKB EP microohmmeters, milliohmmeters, micromillikilloohmmeters (MIKO Group).
  • OLTC transformers diagnostics:
  • Operating principles of different types of OLTC transformers.
  • PKR-2 and PKR-2M OLTC Analyzers aimed for circular diagrams and oscillograms receiving as well as data analysis operations.
  • In-place diagnostics of OLTC using PKR-2M, MIKO-9 and MIKO-8M instruments.

Special interest visitors expressed towards PKR-2M instrument for in-place diagnostics of OLTC of both resistor and reactor type. The instrument enables to make OLTC diagnostics with current-limiting resistors without removing the contactor tank cover. Participants of the presentation appreciated convenience, time saving and quality of measurements within in-place OLTC diagnostics (DRM-test).

Special attention was also attached  to MIKO-10 microohmmeter. The instrument intended for express measurements is very useful when it comes to independent after repair tests of contact joints.

Besides well-known instruments several new developments have been also represented. Milliohmmeter MIKO-9 could not remain without attention due to its wide functionality, large range of resistance measurement and fully automatic measurement process.

During the presentation our specialist also introduced circuit breakers (PKV Group instruments) and represented PKV/M7 instrument.

Participants could get acquainted with several instruments and test their functionality. The visitors could get personal consultations about each instrument and receive more information about new developments.


SKB EP, LLC offers training service including theoretical and practical instruments presentation. Seminar program is offered on individual basis according to the range of instruments purchased and to the equipment available for diagnostics.
