This is KKM Power d.o.o.

KKM Power d.o.o. production facilities and office are located in Ripanj about 20 km outside Belgrad, Serbia.

Core assembly.

Magnetic core assembling is performed manually. The requirements are high; the quality is monitored during all steps in the production process, according to ISO standard.

Test lab.

In our test lab, we can generate up to 1,4 MegaVolt. All tests according to all available standards for magnetic products can be carried out.

Power generator.

Our test lab carries an AEG AC generator with 1 MVA power capacity that we use to test bigger reactors.

Faraday’s cage.

Faraday’s cage for safe and accurate tests, including:

  • – Type tests
  • – Special tests
  • – 3I0 linearity tests
  • – R/X tests
  • – PD tests

Comsol Multiphysics.

The AC/DC Module is used for simulating electric, magnetic, and electromagnetic fields in static and low-frequency applications. Typical applications include inductors, insulators, coils, and sensors, with dedicated tools for extracting parameters such as resistance, capacitance, inductance, impedance, force, and torque.
