ACTIVITIES

Testing

As a laboratory accredited by the National Accreditation Authority (NAH), the High Voltage Laboratory, thanks to its excellent staff, the High Voltage Technology and Equipment Group, and its equipment, is capable of carrying out diagnostic measurements and tasks commissioned by external, industrial parties. Under the leadership of the NFCS, the Laboratory can carry out testing of the insulation and operational reliability of various high-voltage equipment, as well as diagnostic testing and condition assessment of certain equipment and structures.

NAH-accredited tests

Within the scope of NAH-accredited tests, it is possible to carry out accredited inspections and expert assessments of equipment used in practice. The Laboratory is capable of testing equipment for low-voltage, near-live working, as well as equipment for medium- and high-voltage live-line working.

The Laboratory operates a quality management system compliant with MSZ EN ISO/IEC 17025:2018 in the following areas:

  • Acceptance and periodic testing of insulated-boom aerial platform vehicles
  • Acceptance and periodic testing of electrostatic protective clothing
  • Acceptance and periodic testing of insulating ropes
  • Acceptance and periodic testing of overhead-line gondolas
  • Acceptance and periodic testing of insulating rods
  • Determination of the electric strength of solid insulating materials
  • DC, AC and impulse voltage testing of high-voltage insulation
  • Testing of the levels of electric and magnetic fields generated by AC electric power systems

For the exact list of tests and standards that can be carried out under accredited status, please refer to our Scope of Accreditation. The laboratory issues its assessments in accordance with the ILAC G8:09:2019 4.2.1 binary decision rule.

Diagnostic tests

From the point of view of the operation of electrical networks, knowing the condition of individual pieces of equipment can be considered a key question. The reliable operation of the often very expensive equipment used in the electric power network is essential for ensuring the electricity supply. Properly carried out diagnostics of the various pieces of equipment are needed to ensure continuous operation. The High Voltage Technology and Equipment Group is able to carry out professional diagnostic testing of electrical equipment in the High Voltage Laboratory:

  • Complex diagnostics and condition assessment of cables and cable networks
  • Complex diagnostics and condition assessment of transformers
  • Complex diagnostics and condition assessment of electrical switching devices
