Prof. Dr Oleh VELYCHKO, Director of the Research and Production Institute for Measurement of Electromagnetic Quantities and Conformity Assessment of Measuring Instruments (Institute №3) represents Ukraine in the international measurement community as a Member of the IMEKO Technical Committee 4 Measurement of Electrical Quantities (IMECO TC4), a technical expert of the IEC Technical Committee 85 Measuring equipment for electrical and electromagnetic quantities (IEC TC85).

Representative of the Institute is a Member of EURAMET/TC-EM - Electricity and Magnetism and an Official Observer in the Consultative Committee for Electricity and Magnetism (CCEM) of the International Committee of Weights and Measures (CIPM).

Where Ukraine is P-member:
IEC/TC 85 - Measuring equipment for electrical and electromagnetic quantities.

Where Ukraine is O-member:

• OIML/TC12 - Instruments for measuring electrical quantities;
• IEC/TC 13 - Electrical energy measurement and control;
• IEC/TC 62 - Medical equipment, software and systems;
• IEC/TC 66 - Safety of measuring, control and laboratory equipment.

Institute has created and maintains 10 National measurement standards (NMSs) to meet the needs of customers in the field of high-precision measurement of  electromagnetic quantities:

• National measurement standard of electrical capacitance and loss factor (DETU 08-06-01);
• National measurement standard of electric power and power factor (DETU 08-08-02);
• National measurement standard of inductance and loss angle tangent (DETU 08-09-09);
• National measurement standard of angle of displacement of phase between two voltages (DETU 08-07-11);
• National measurement standard of DC voltage within the range from 1 kV to 180 kV (DETU 08-04-99);
