Reference standard of harmonic factor unit

Developed and operated since 2008

Reference standard of harmonic factor unit


Standard composition:

  • hardware block;
  • PC;
  • special software;
  • multimeter 3458А;
  • oscillograph DSO 3202A

Metrological characteristics:

  • frequency – 0,01-200 kHz;
  • harmonic factor – 0,003-100 %;
  • additive error – (1-3)•10-3 %;
  • multiplicative error – (0,3-0,5)•10-2 %;
  • standard deviation at reproduction – 0,003 %;
  • standard deviation at transfer – (0,2-2)•10-3 %

Calibration and measurement capabilities of the standard are confirmed through the traceability to the National standard of the unit of the voltage alternating current within the range of frequency 10Hz-2GHz of the Republic of Belarus and to the National standard of the units: time – second, frequency – Hertz and the time scale of the Republic of Belarus by means of conducting periodical metrological attestation.

Sources of traceability:

  • Belarus, RUE «BelGIM», National standard of the units: time – second, frequency – Hertz and the time scale of the Republic of Belarus (NS RB 1-95) ;
  • Belarus, RUE «BelGIM», National standard of the unit of voltage alternating current within the frequency range 10 Hz – 2 GHz (NS RB 5-01)

Scope of application:

Used to assure traceability of the derivative unit KG to the main international units of physical quantities and the transfer of the KG unit size to the standard and working measuring instruments during verification, calibration and metrological certification of measuring instruments, that are used in the following fields:

  • device making,
  • power engineering,
  • communications,
  • medicine,
  • in IT and computing machinery.
