Abstract:

Using electronic converters (non-iinear loads) in an electrical system brings many benefits. However, the use of them causes harmonics in electrical networks and distorts the voltage and current waveforms, greatly affecting to the normal working and safety conditions as well as the longevity of electrical appliances. Therefore, there is a need to take measures to overcome the harms of harmonics to electrical devices caused by nonlinear loads. The article analyzes and evaluates the effect of harmonics on devices by nonlinear loads in the 6 kV network of Nam Mau Coa! Company and suggested the suitable solution to eliminate the negative effects of harmonics on the devices in the network.
