A study on radiated interference emitted by power tool appliances within 30 MHz to 1 GHz

摘要

The paper presents the results of measurements of electromagnetic disturbances of radiated power tools in the frequency range 30 MHz -1 GHz. Experimental studies were carried out in a GTEM cell. The results obtained were compared with the directive defining the requirements for common devices, electric tools and other similar equipment. The maximum quasi-peak value measured was 65.41 dBpV/m, which exceeds the normative values by 10dB. Using statistical analysis, the following variables were evaluated in the context of characterisation of particular types of devices.
