Main Functions
The GE DFP100 Digital Feeder Relay has a variety of protection functions, including but not limited to:
Overcurrent protection: able to detect and respond to overcurrent conditions on the feeder, cutting off faulty circuits in a timely manner, preventing equipment damage and fire and other safety accidents.
Ground fault protection: It can detect ground faults on the feeder to ensure the safe and stable operation of the power system.
Reclosing function: After the fault is removed, it can automatically reclosing to restore the power supply of the power system and improve the reliability and stability of power supply.
Technical features
Digital technology: adopts advanced digital technology to achieve high-precision current and voltage measurement and fault detection.
Programmability: With programmability, users can set the protection parameters and logic according to the actual needs, and flexibly adapt to different power system application scenarios.
Communication function: support a variety of communication protocols and interfaces, capable of data exchange and remote monitoring with other power equipment, to achieve intelligent management of power systems.
Application Scenarios
GE DFP100 digital feeder relay is suitable for power systems of various sizes, especially for places that require high-precision protection and reliable power supply, such as:
Industrial plants: to ensure the normal operation of production equipment and the stability of power supply.
Commercial buildings: to ensure the normal operation of commercial activities and power safety.
Power system: improve the overall reliability and stability of the power system and reduce the impact of faults on the power system.
Use and Maintenance
Installation and Commissioning: When installing the GE DFP100 digital feeder relay, make sure that the equipment is properly grounded and commissioned and set up according to the product manual.
Regular Inspection: Regularly inspect and maintain the relay to ensure that it is in good working condition.
Troubleshooting: When the relay fails, the cause of the failure should be identified and repaired in time to ensure the normal operation of the power system.
