Badania Elektryczne i ElektroniczneWe carry out tests in the following scope:

  • AC and DC voltage measurements,
  • AC and DC current measurements,
  • frequency and capacity measurements,
  • inductance measurements,
  • resistance measurements and diodes tests,
  • resistance of leakage to earth (floors, working surfaces, stillage, trucks, chairs),
  • resistance of system “human / footwear / floor” (efficiency of earthing by ESD footwear and the floor),
  • resistance between points (floors, working surfaces, flat materials, clothes),
  • electrification,
  • dielectric strength,
  • isolation resistance of cable lines, transformers, motors and other electrical power devices, also devices used in telecommunications,
  • separation distances,
  • cells and batteries capacitance,
  • resistance for short-circuit of cells and batteries,
  • protection against residual voltages,
  • system continuity of protecting wires and resistance of protecting wires and equalizing connections,
  • surface resistance RS, volume resistance RV, resistance between points RP of non-metal materials,
  • resistance of pipes and hydraulic hoses made of plastic and rubber,
  • thermal – heating, temperature rise, maximum temperature with the use of contact and non-contact method (thermovision),
  • intrinsic safe systems.

Our wide scope of tests includes:
