Semianechoid chamber

Anechoid chamber

Description:

EMC laboratories EVPÚ a.s. belong to the top workplaces for EMC measurement in Europe, in particular the Semianechoid chamber of dimensions (L x W x H): 20.5 m x 12.4 m x 7.80 m equipped with top measuring equipment and trained personnel with long-term experience.

  • we provide equipment tests to meet the requirements of Directive 2014/30/EU of the European Parliament and of the Council on the harmonization of legislation of member states relating to electromagnetic compatibility (EMC)
  • we provide advice and technical cooperation in the testing and development of components and technical units

Measurements:

  • measurement of the magnetic and electric component of the electromagnetic field;
  • measurement of the level of interfering clamp voltage;
  • measurement of radiated power;
  • measurement of the level of the electric component of the electromagnetic field;
  • measurement of the level of the magnetic component of the electromagnetic field;
  • measurement of low-frequency currents;
  • measurement of voltage amplitude changes in the distribution network;

Resilience detection:

  • detection of resistance to electrostatic discharge
  • detection of immunity to interfering electromagnetic fields;
  • detection of resistance to electrical impulse bursts (burst test);
  • testing for resistance to voltage surges;
