What is harmonics issues in AC and DC grid? In AC and DC grids, harmonics refer to the presence of frequency components that are integer multiples of the fundamental frequency. Harmonics can be problematic because they can cause various issues such as: Voltage and Current Distortion: Harmonics in the grid can distort the shape of the voltage and current waveforms, resulting in distorted sine waves...

Power factor is an important technical indicator of the power system. It represents the ratio of active power to apparent power in an AC circuit. This ratio is usually expressed as a cosine function (cosφ). The size of the power factor reflects the energy utilization efficiency of the power supply output. If the power factor is too high, that is, the reactive power is too low, it will reduce the r...

What is nonlinear load? A nonlinear load is a load whose current is not proportional to its voltage. Since some electronic components, such as transistors and diodes, exhibit nonlinear characteristics when operating, in actual power consumption, some electrical equipment connected to the load will deform the current waveform. This deformation causes the voltage to distort and generate additional f...
