How does a HPS Reactor reduce Line Notching?
Whenever a rectifier converts AC power to DC, using a nonlinear device, such as an SCR, the process of commutation occurs. The result is a notch in the voltage waveform. The number of notches is a function of both the number of pulses and the number of SCR’s in the rectifier.
Reactors are used to provide the inductive reactance needed to reduce notching, which can adversely effect equipment operation.
