AccuSine® PCS AHF
Class 5820
The problem:
High levels of harmonics generated by non-linear loads can have significant negative impact in the facility electrical system. It can cause malfunction of the equipment, disrupt plant operation, thus, resulting loss of productivity.
Harmonic filtering:
The AccuSine Power Correction System (PCS) is Active Harmonic Filter (AHF) which actively injects opposite harmonics current on the source side of the load and it:
Power Factor Correction and Dynamic VAR Compensation:
AccuSine PCS features a 100 microsecond response providing for dynamic VAR injection to reduce voltage sags created by inductive load switching. In addition, AccuSine PCS can inject peak current at 2.25 times its rms current rating for 3 cycles. AccuSine PCS can also operate in a dual mode where current is first injected to reduce hamonics and any excess current capacity is used to improve the power factor.Other Features:
Accusine PCS Sizing
