Guía de armónicos de variadores de frecuencia para sopladores de aireación en tratamiento de agua
Water treatment plants run large aeration blowers on VFDs whose speed tracks dissolved-oxygen setpoints, so harmonic current at the blower feeder rises and falls with biological demand rather than with···
