ELECTRICAL POWER FACTOR CORRECTION CAPACITORS (PFCC)
- Description: All items described within this section shall comply with the provisions of Section 15001: General M&E Requirements. Power Factor Correction Capacitors (PFCC) shall be provided to improve the overall power factor of the plant/equipment to 0.93 lagging (or better) to meet ADDC regulations. PFCC shall be designed and manufactured for automatic centralised operation for site-wide Power Factor compensation by employing multiple steps. It shall be contained within a standalone Factory Built Assembly (FBA) in a minimum Form 2 Enclosure as described under Section 16020: Factory Built Assembly (FBA). The enclosure shall be of equal height of the associated MCC and located adjacent to it or at other suitable location within the MCC room. The PFCC enclosure shall be fitted with forced ventilation fan and louvres as necessary. The IP rating when fitted with forced ventilation shall be at least IP43. The PFCC equipment shall be disconnected whenever the associated MCC is fed by a generator set. The PFCC enclosure shall be sized to accommodate an additional spare step of equal rating for future use. Internal wiring within the PFCC enclosure shall be fire-retardant to 105ºC. The design of the PFCC shall take into account any harmonic filter installations connected to the same power distribution system so as to avoid any LC resonance with these and any upstream transformer reactances.
