Utilities will often penalize for poor power factor caused by direct-connected motors on cooling plant, harmonics from motor drives and even some server loads and UPSs.
Standard power factor correction using capacitors is difficult to apply in data centers, especially where standby generators are installed. Some server loads, particularly when heavily loaded, can cause a leading power factor, which is a particular problem for standby generators.
ABB’s PCS100 RPC (reactive power conditioner) is ideal for correcting power factor and low-order harmonics in data center applications.
