In all electrical and electronic systems, cables are the most important equipment. The basic function of the cables is to send signals from one point to another. However, in addition to these functions, cables can carry unwanted signals. This is called interference through conductivity. Conducted emission tests are carried out to determine these interaction values. In addition, the cables act as an antenna and can emit signals circulating on them. This is called interference through radiation.
Cables of different lengths and specifications used in an electrical or electronic system or device behave as an antenna transmitting at different frequencies. The cables are therefore a strong source of electrical interference and magnetic interference. Because of this interaction, the performance required in the devices is important. Two basic elements determine the performance of the cable: shielding material and cable screen grounding. Some cables provide good shielding from external interference, but may be unprotected against magnetic field interference.
Companies that produce electrical and electronic equipment are required to carry out the necessary tests and measurements, not only for cables, but also for all parts and, ultimately, for the total. One of these test and measurement methods is the transmitted emission tests. These tests and measurements are performed in all laboratories.
our organization transmission emission tests within the scope of EMC tests., in accordance with the relevant regulations, standards and test methods published by domestic and foreign organizations. These standards are based on a few standards:
- TS EN 55011 Industrial, scientific and medical equipment - Radiofrequency distortion characteristics - Limit values and measuring methods (CISPR 11: 2009, modified)
- TS EN 50561-1 Power line communication devices for low voltage installations - Radio disturbance characteristics - Limits and measuring methods - Part 1: Domestic appliances
- TS EN 55014-1 Electromagnetic compatibility - Specifications for household appliances and similar appliances - Part 1: Propagation
Our institution, from the ÖSAS Accreditation Institution, Accredited according to TS EN ISO / IEC 17025 standard.
