Negative phase sequence describes an undesirable condition in a three-phase electrical system where the voltage or current vectors rotate in the opposite direction to the standard positive sequence. This unbalance leads to issues like excessive heating in motors, reduced efficiency, increased vibration, and potential damage to equipment, making its detection and mitigation crucial for system reliability and longevity.
