AUTOMATIC POWER FACTOR CORRECTION PANEL( APFC )

---

Automatic Power factor correction panel is fully automatic in operation and can achieve desired power factor under fluctuating load onditions.

Unique Features of SAHA SPRAGUR make APFC Panel :

• The PF Controller offered is BELUK the best presently available in the market.
• Due to multi stage switching fine correction is possible and so PF can be easily maintained near to unity.
• The capacitor stages are switched on by rotation to equalize working hours.
• Auto & Manual operation facility provided.
• To reduce transients in the system no stage of switching is more than 30 KVAR and no individual capacitor cells exceeds 15 KVAR.
• Phenomenal reduction in Panel size and so occupies very less space.
• Each capacitor bank is modular, detachable back up mounting in construction which facilitates easy maintenance and future capacity expansion.
• Control winding is modular and features quick connect, plug in type connection.All capacitor cells are suspended and spaced in order to maximise air flow and cooling within the units.
• MCB protection is provided before the contactors with adequate short circuit and thermal ratings. Heavy duty contactors of suitable rating is used for switching capacitors with high rupturing capacity. The MCCB used for main incomer is also of suitable rating of highrupturing capacity. All above components used are the best available like ABB/SCHNEIDER/Siemens etc.
• All interconnections are envisaged using copper cable duly insulated using tin plated copper lugs to ensure no contact resistance and consequently no heating. . The enclosures are manufactured in 14/16 gauge CRCA steel, seven tank processed and powder coated. They are indoor type and is dust, vermin and weather proof. Further it is user friendly and aesthetically designed.
• Above all , trouble shooting, installation and general maintenance procedures are made simple and easy.Capacitors are available for visual inspection and replacement. Panels are provided with earthing terminals and caution board as per IE rules.
• Electrical safety is a paramount importance and the offered APFC demonstrates this unmatched safety feature in compliance with UL/CSA and National Electric Code.
• All busbars and live parts are shrouded and capacitors are provided with quick discharge resistors and are inaccessible for ordinary persons.
• All components used inside the system are rated for more than the continuos currents.
• For eg. The cable used are 10sq mm or above for interconnection enabling better current density and lower resistance. This reduces losses in the Panel and reduces heating.
• More than all the above, SPRAGUE is world leader in Power Factor correction, is available in more than 15 countries and is recommended by worlds reputed Defence and Research Organsisations.So you can be sure of dealing with the leader.
