Electromagnetic Compatibility

 Compatibilità Elettromagnetica

 

 

The term “Electromagnetic Compatibility” (abbreviated as EMC), defines the field of electrical engineering that studies the involuntary generation, propagation and reception of electromagnetic energy that can cause undesired effects, such as electromagnetic interference (EMI) or damage to devices. The objective of the EMC is the proper operation of the different equipment in a common electromagnetic environment

 

EMC (Electromagnetic Compatibility)

It consists in verifying that the disturbances emitted by the device under test are lower than the limits imposed by regulations applicable to the product itself. The purpose of this type of test is to avoid other devices from being disturbed, or from interfering with radio communications in the assigned bands.

EMI (Electromagnetic Immunity)

It consists in verifying that the disturbances generated by the devices operating in the vicinity do not compromise the proper operation of the device under test.
 
 

The Electromagnetic Compatibility (EMC) Laboratory  has all the equipment necessary to perform a wide range of FULL COMPLIANCE tests that go well beyond the normal tests required by Directive 2014/30/UE . All instrumentation strumentazione is subject to periodic calibration referable to nationally recognised samples according to the ISO 17025 standard.. 

The purpose of the Electromagnetic Compatibility tests is to verify the suitability of an apparatus to operate in its electromagnetic environment in a satisfactory manner without deterioration in the presence of electromagnetic disturbanceand without producing unacceptable electromagnetic disturbances in other equipment in the same environment.

 
 
Below is a list of the main tests performed:
 

  • Conducted Emissions measurement

Verification of the level of electromagnetic disturbance generated by the device under test and connected to power, telecommunication or I/O networks.

  • Radiated Emissions measurement  

Verification of the level of electromagnetic disturbance generated by the device under test and radiated into the surrounding environment.

  • Harmonic Current measurement

Verification of the emission level of the harmonic current injected on the supply lines

  • Flicker Noise Emissions

It aims at verifying voltage variations, voltage fluctuations and flicker in low voltage power supply systems.

  • Conducted Immunity test

It aims at testing the level of immunity to disturbances originating from power, telecommunication or I/O networks.

  • Radio Frequency Radiated Immunity test

It aims at testing the level of immunity to radio frequency disturbances radiated in the surrounding environment.

  • Burst Noise Immunity test

It aims at testing the level of immunity to high frequency repetition disturbances.

  • Surge Disturbance Immunity test

It aims at testing the level of immunity to unidirectional peaks caused by switching and transient overvoltage due to lightning strikes.

  • ESD Disturbance Immunity test

It aims at testing the level of immunity to electrostatic discharge due to direct or indirect user contact.

  • Magnetic Fields Immunity test

It aims at testing the level of immunity to magnetic fields at a 50 or 60 Hz network frequency.

  • Voltage Variations Immunity

It aims at testing the level of immunity to changes in power supply voltage.
