Electrical Phase Sequence Panel – Overview
An Electrical Phase Sequence Panel is a protective and monitoring device used to ensure the correct sequence of three-phase power supply (R-Y-B). It prevents equipment damage caused by phase reversal, phase failure, or voltage imbalance in industrial and commercial electrical systems.
Key Functions
Phase Sequence Monitoring – Ensures correct R-Y-B sequence
Phase Failure Protection – Detects loss of any phase
Phase Reversal Protection – Prevents wrong phase connection
Voltage Monitoring – Monitors over-voltage and under-voltage conditions
Automatic Tripping – Disconnects supply in case of fault
