Electrical mechanical and environmental tests

Electrical testing, LVD

The test laboratory in Siemianowice Śląskie carries out tests in the following areas

measurements of direct and alternating voltages

  • alternating and direct current measurements
  • frequency and capacitance measurements
  • inductance measurements
  • resistance measurements and diode tests
  • leakage resistance to earth (floors, work surfaces, shelves, trolleys, chairs)
  • resistance of the “man/shoe/floor” system (effectiveness of earthing through ESD shoes and the floor in question)
  • point-to-point resistance (floors, work surfaces, flat materials, clothing), electrification,
  • electrical insulation strength
  • insulation resistance of cable lines, transformers, motors and other electrical equipment, also equipment used in telecommunications,
  • insulation clearances
  • capacity of cells and batteries,
  • short-circuit resistance of cells and batteries,
  • protection against residual voltage
  • continuity of protective circuitry and resistance of protective and equalising circuits,
  • surface resistance RS, RV cross resistance, resistance between RP points of non-metallic materials,
  • resistance of pipes and hydraulic hose made of plastic and rubber,
  • thermal – heating, temperature rise, maximum temperature
  • using contact and non-contact methods (thermal imaging),
  • intrinsically safe systems.

We carry out tests in the field of European, IEC and national standards, among others.
