Comparison of 2-150kHz emissions between laboratory and LV grid
Coordinator: Paul Wright
The impedance of a given low voltage (LV) network has an effect on the 2-150kHz conducted emissions generated by an electrical appliance connected to that network. It is therefore important to study the emission characteristics of mass-market electrical appliances under different LV network conditions and compare the measurements with the emission measured according to the CISPR 16 and IEC 61000‑4‑7 emissions measurement methods in the laboratory.
These comparisons assess the suitability of the compliance testing regime (CISPR 16 and IEC 61000‑4‑7) by comparing laboratory emission measurements of a selection of appliances, with equivalent tests in real LV networks. The deviation of results in different networks is used to assess the applicability of the various artificial mains networks that attempt to represent the impedance of a typical mains network. The LV network emissions data helps to draw conclusions about the suitability of grid compatibility levels in the 2-150 kHz range as specified in IEC 61000-2-2.
