What makes ABB'S PCS100 RPC stand out?

Displacement Power Factor Correction 
 With the PCS100 RPC installed reactive and harmonic currents are supplied via the ultra fast power electronic inverter. Voltage and current feedback from the point of connection allows the Power Factor to be controlled according to the set-point. Without the PCS100 RPC, the reactive and harmonic currents create additional load on transformers and switchboards, increasing losses and reducing lifetime.
Distortion Power Factor Correction
 The PCS100 RPC is able to provide harmonic filtering of two defined frequencies up to a maximum harmonic of 7th. Combining harmonic filtering and displacement power factor correction with VAr injection gives a complete power factor solution, considering both displacement and distortion power factor. This lowers energy consumption, increases efficiency so that higher loadings are possible and lower operating temperatures and increasing lifetime are achieved.
Imbalance Correction
 Voltage imbalance together with rectifier loads is particularly harmful, as it causes overloading of phases inside the rectifier itself and in extreme cases premature failure. The PCS100 RPC is capable of correcting imbalance in a three phase network by injecting negative sequence currents. This feature can be used to balance loads across all phases.
 Voltage Clamping  The PCS100 RPC has a unique feature whereby voltage thresholds can be set. When exceeded, reactive current is injected or absorbed to boost or reduce the voltage.  This is particularly useful in dynamic applications where motor starts or other inrush events are frequently experienced.  
 Voltage Control  This configuration can be used where load related voltage problems are experienced (i.e. dynamic loads or high impedance utility power supplies).  Under this application the voltage is controlled by injecting or absorbing reactive power.
