Electrical Power Testing: Inspection of Electrical Power Plants, Devices, and Equipment

The electrical power system consists of generation, transmission, distribution, and consumption of electrical energy. The fundamental task of the electrical power system is to provide reliable and high-quality electricity supply, which includes production, transmission, distribution, and consumption of electrical energy.

In the field of electrical power engineering, we offer the following certifications:

  • Testing the functionality of electrical power plants, electrical devices, and electrical installations.
  • Primary and secondary testing of electrical protections and protective relays of all types and voltage levels.
  • Testing protection against simultaneous direct and indirect contact with live parts.
  • Testing protection against direct contact with live parts (insulation, covering, barriers, passages, residual current devices).
  • Testing protection against indirect contact with live parts implemented in TN, IT, and TT systems (loop resistance testing, short-circuit current measurement, testing of residual current devices – RCCBs, protective insulation, galvanic separation, and potential equalization).
  • Measurement of insulation resistance of electrical power plants, electrical devices, electrical transformers, electrical generators, electrical motors, electrical cables, and electrical installations.
  • Measurement of step and touch voltages, grounding voltage measurement, and measured potential difference.
  • Measurement of grounding system resistance for power and protective systems.
  • Measurement of insulation resistance of floors and walls.
  • Inspection of lightning protection installations and measurement of lightning protection system grounding resistance.
  • Measurement of dielectric strength of insulation media in the laboratory.
  • Measurement of illuminance intensity.
  • Measurement of galvanic connection resistance on potential equalization installations.
  • Inspection, testing, and measurement of cathodic protection devices.
  • Inspection and testing of welding devices, inspection and testing of portable tools and devices with electric motors (mixers, drills…).
  • Testing, installation, and maintenance of devices made in IP protection and explosion-proof Ex execution.
  • Measurement of electrical quantities such as voltage, current, power, energy, frequency, power factor, magnetic and electric fields, capacitance, inductance, and resistance in accordance with available instruments.
  • Checking the operation of indicating and recording instruments and verifying the phase sequence in electrical power plants.
  • Determining the degree of heating of parts of electrical power plants and equipment, busbars, electrical devices, etc., by thermal imaging method.
  • High-voltage testing of personal protective equipment subject to standards with mandatory application for conditions of periodic testing (HV boots, gloves, indicators, insulating mats…).
  • High-voltage testing of dielectric strength of insulation of underground fuel tanks before installation, underground pipelines, installation materials, hard and liquid insulants….
  • Measurement of static electricity.
