On July 30, 2021, the decree of the Board of the Eurasian Economic Commission (EEC) № 105 dated July 27, 2021 approving the draft TR EAEU "On safety of high voltage equipment" was published and immediately entered into force.

Now the draft will be reviewed by the Eurasian Economic Commission (EEC) Council for final approval.

Scope of the regulation

The technical regulation applies to the high voltage equipment put into circulation on the territory of the Eurasian Economic Union (EAEU) and is intended for the production, conversion, distribution of electrical energy or to be used in the transmission of electrical energy, in particular:

  • inputs;
  • automatic breakers, including load breakers;
  • high frequency shields;
  • insulators;
  • cables, including cable fittings and insulated power wires;
  • complete switchgears;
  • complete transformer substations;
  • condensers;
  • electric rotating machinery;
  • nonlinear voltage limiter;
  • surge-voltage protectors;
  • semiconducting converters ;
  • protected wires;
  • surge arrestors;
  • disconnectors, earthing switches and short-circuiting devices with actuators;
  • electrical reactors;
  • high-voltage resistors;
  • current leads;
  • voltage, current and power transformers;
  • voltage regulation devices under load of power transformers.

In addition, equipment consisting of several parts of the devices listed above will also fall within the scope of the regulation. For example, it includes: a combined current and voltage transformer, a switch-disconnector, etc.

Conformity assessment of the equipment in compliance with regulations

According to the requirements of the draft regulation (Article 40, Article VIII), high voltage equipment will be subject to a mandatory declaration of conformity before being put into circulation.

The declaration of conformity of high voltage equipment will be registered according to one of the schemes: 3d, 4d, 5d or 6d. In all cases, the declaration will be based on the results of tests in an accredited testing laboratory. When using the 6d scheme, additional certification of the management system will be required.

If high-voltage equipment won’t be produced in accordance with the standards included in the list of regulations (currently the list is under development), then the declaration will be replaced by an obligatory certification under one of the schemes: 1c, 2c, 3c or 4c.

The applicant can also decide to replace the declaration with certification.

Effective date of the regulation

It is planned that the regulation on safety of high voltage equipment will come into force on July 1, 2024.
