AUTOMATIC PHASE SEQUENCE CORRECTOR PANEL

AUTOMATIC PHASE SEQUENCE CORRECTOR PANEL

RuncoN Phase Sequence Corrector Panel is a specialized electrical panel designed to detect and correct the phase sequence of a three-phase power supply. Proper phase sequence is critical for the safe and efficient operation of three-phase equipment like motors, pumps, and compressors. If the sequence is incorrect, it can cause motors to run in reverse, leading to operational issues or damage.

Main Components

1. Phase Sequence Relay: Detects the sequence (R-Y-B) of the incoming supply and identifies any phase reversal.
2. Correction Mechanism: Employs automatic or manual switching of phases to restore the correct sequence.
3. Contactors or Relays: Perform the actual switching to correct the sequence.
4. Indication and Alarms: Visual (LED) or audible alarms indicate phase sequence errors or loss of phase.
5. Overload and Short-Circuit Protection: Protects the panel and connected equipment from faults.
6. Control Transformer: Provides low-voltage control signals for relays and indicators.

Working Principle

1. Detection: The phase sequence relay continuously monitors the incoming three-phase supply.
2. Correction: If an incorrect sequence or phase failure is detected, the panel initiates the corrective action by switching the phases to restore the correct sequence.
3. Restoration: Once the sequence is corrected, the system allows power to flow to the load.
