Can I use a power factor correction capacitors (PFCC) with an active harmonic filter?
Power factor correction capacitors (PFCC) can be used on systems with an active harmonic filter (AHF). AHF’s harmonic mitigation may even be required to protect PFCC from excessive heating and failure caused by harmonics. PFCC cannot be installed on the load side of AHF current sensors. PFCC should be installed between the AHF and the utility point of common coupling (PCC).
