summary
With the development of power electronic control technology, there have been more demands for high-quality power supply.
High-capacity nonlinear loads of inverter, rectifier, welder, converter, and arc furnace generate harmonics and reactive power, causing voltage distortion and flicker.
The diagnosis & analysis, simulation, and construction based on practical experiences make it possible to bring about the optimal engineering results.
