SFR-M Capacitor Bank

SFR-M series LV(low voltage) dynamic harmonic suppression reactive compensation module is designed for solve the problem of harmonic and power factor in the situation of serious harmonic pollution in 0.4kV low voltage power distribution network. It is used as an integrated reactive power compensation module with functions of power factor enhancement, effective harmonic suppression, reduction of line loss and improvement of power quality. The components of dynamic harmonic suppression reactive compensation module include DSP digital processing circuit, highly integrated detection, control, protection, display unit, zero crossing switching module, discharge and air cooling unit, filter reactor, low-voltage filter power capacitor and function module operation status indicator circuit. This module is a new generation of dynamic reactive compensation equipment for 0.4kV low voltage distribution network which is suitable for the load changed frequently and the system request high voltage quality. It's a typical dynamic tracking compensation integration module with switching time≤20ms.
