EMC laboratories in EVPÚ a.s. belong to top-level workstations for EMC measurement. We provide type examinations of developed devices in accredited laboratories with state of the art measuring equipment and in large chambers. Our laboratories provide:

Measurement of:

  • Low-frequency emissions
  • Interference terminal voltage
  • Interference field strength
  • Radiated interference power

Measurement of resistance against:

  • Electrostatic discharges
  • Radiated high-frequency electromagnetic field
  • Fast transients (Bursts)
  • Surges
  • Interference induced by high-frequency fields propagated through lines
  • Magnetic field of mains frequency
  • Short time voltage drops, short interruptions and voltage fluctuations
