Conducted Emission Test

The main emission tests carried out in authorized laboratories within the scope of EMC tests are as follows:

  • Conducted emission
  • Electric field, radiated emission
  • Harmonic and flicker

Transmission diffusion or conductivity diffusion tests are carried out to determine the levels of electromagnetic pollution emitted by the transmission to the telecommunications or energy network to which an electrical or electronic device is connected. In this test, the voltage and current values ​​of the electrical or electronic device or system are measured. Voltage values ​​are measured by LISN (Line Impedance Stabilization Network) and current values ​​are measured by current probe.

The electrical or electronic device generates electromagnetic energy when operating, and a certain amount of this is directed to the power cord of the device. In order to limit the amount of interference the device can return, these emissions must be measured in laboratories. This value should generally be between 150 kHz and 30 MHz. International standards generally apply this value. However, this frequency range may be higher or lower for certain standards. These measurements are made to ensure that the power supply remains relatively clean and will not affect other devices in the vicinity.

In summary, a device performs electromagnetic radiation by conductivity through lines such as energy, data and telecommunications. The level of this diffusion is determined by the tests performed and compared with the limits of certain standards.

Essentially the electric field, radiation emission measurements (electromagnetic interference emission measurements) are:

  • Measurement of electromagnetic wave radiation (radiated magnetic field emission)
  • Interference wave voltage measurement (conducted emission)
  • Measurement of interference disturbance (power disturbance)
  • Measurement of smooth non-continuous brittle interference waves
  • Measurement of low frequency network interference waves

Many electromagnetic compatibility (EMC) tests are performed in authorized laboratories. our organization conducted EMC tests within the scope ofis in compliance with the standards and test methods published by the domestic and foreign institutions.

Our institution, from the ÖSAS Accreditation Institution, It is accredited according to TS EN ISO / IEC 17025 standard and the tests, measurement, analysis, inspection and inspection procedures and reports are accepted as valid in private and official audits.
