Active Filter System Implimentation

Application of adjustable speed drives (ASDs), especially for industrial applications, provide significant energy savings and increased productivity compared to constant speed motors. The Electric Power Research Institute (EPRI) estimates that electric motors constitute 60% of total power utilization. However, only a small percentage of these motors are ASDs. It is estimated that use of ASDs for variable speed operation, such as for compressors, pumps and fans, will result in 30% energy savings and in a short payback period for additional ASD costs. EPRI projections indicate that a large percentage of constant speed motors will be retrofitted with ASDs.
