Typical Application Fields
- Protection of large electric motors in industries such as power, petrochemical, metallurgy, papermaking, and textiles.
- Feeder protection and fault isolation in power distribution systems.
- Critical production equipment requiring high reliability and remote monitoring.
- Cooperates with GE EnerVista™ Software to realize power quality monitoring and preventive maintenance.
Installation and Maintenance Guidelines
- Pre-installation Preparation: Confirm correct secondary wiring of CT/PT; use an insulation tester to check the grounding of communication cable shielding layers.
- Wiring: Follow the wiring diagram in the product manual to ensure separate arrangement of power, signal, and communication lines to avoid interference.
- Commissioning: Configure parameters via GE EnerVista™ Software; perform self-test before putting into operation.
- Routine Maintenance: Check alarm records and event logs every 6 months; calibrate current/voltage measurement once a year (OMICRON CMC tester is recommended); update firmware regularly.
- Troubleshooting: Use the local display panel or remote monitoring system to view fault codes for quick problem location.
