Selective Ground Resistance Measurement

Multifunctional measuring instruments are used to determine whether the earthing systems are correctly installed and functioning correctly. Selective grounding resistance measuring devices do the work of many different measuring devices on their own. Organizations and laboratories providing control and inspection services prefer these types of devices. These devices test the electrical installation in newly constructed buildings or existing buildings in accordance with the standards published by domestic and foreign institutions. The most commonly used standards are:

  • TS EN 61557-1 ... Equipment for testing, measuring or monitoring protective devices - Part 1: General specifications
  • TS EN 61557-2 ... Section 2: Insulation resistance
  • TS EN 61557-4 ... Part 4: Ground connection and equipotential bonding resistance
  • TS EN 61557-5 ... Section 5: Resistance to earth
  • TS EN 61557-7 ... Section 7: Phase sequence
  • TS EN 61557-10 ... Section 10: Testing, measuring and monitoring protective devices
  • TS EN 61557-12 ... Chapter 10: Performance measurement and monitoring devices
  • TS HD 60364-4-44 Electrical installation in buildings - Part 4: Protection for safety - Part 44: Protection against overvoltages Protection of low-voltage installations against faults between high-voltage systems and earth
  • TS HD 60364-4-41 ... Part 41: Protection against electric shock
  • TS HD 60364-5-54 ... Part 54: Selection and installation of electrical equipment, earthing arrangements and protective conductors

Grounding measurements include the following basic services: insulation resistance measurement, plug-in grounding measurement, three-wire grounding measurement, grounding measurement under energy, selective earth measurement under energy, line impedance test, loop impedance test and leakage current relay test. All these measurements and tests are carried out by authorized persons such as electrical engineers, electrical technicians and high technicians.

Our company, within the framework of electrical safety examinations, selective Grounding resistance measurements in accordance with the relevant regulations, standards and test methods published by domestic and foreign organizations. In this regard, our company, the Turkish Accreditation Agency (TÜRKAK), Accredited according to TS EN ISO / IEC 17025 standard.
