Introduction
Auto Phase Corrector is a device that is designed to maintain the sequence of phases and keep them 120 degrees apart to prevent motor, industrial loads, and other three-phase equipment from rectifying immediately due to an improper sequence of incoming phases.
Functionality
APC works by detecting incoming phases for phase sequence, over/under voltage, phase loss, and single-phases. When these parameters are within an acceptable range, it allows power to flow at the output. This prevents the motor from rotating in the reverse direction without serving its intended purpose and drawing power.
Protection
The APC also protects against phase loss, over/under voltage, and single-phasing. These problems can lead to the heating of the winding. HPCS manufacturers use APCs to overcome issues with improper phase sequences and other problems. This ensures the de-facto functioning of three-phase operated machines without any manual intervention.
Capacities Available
APCs are available in a range of capacities, including 6, 9, 12, 15, 20, 25, 30, 40, 50, 60, 75, 90, 100, 120, 125, 150, 200, 300, 400, and 500 KVA.
