Information About 735-5-5-HI-485
The 735-5-5-HI-485 is a microprocessor-based protection relay from General Electric’s 735 series, engineered for feeder protection in medium and low-voltage power systems. It is equipped with standard 50/51 phase overcurrent and 50G/51G ground overcurrent protection functions, ensuring dependable fault detection and isolation. The relay supports 5 A current transformer inputs for both phase and ground measurements, making it compatible with common CT configurations. Designed for flexible installation, it operates across a wide control power range and includes RS485 2-wire communication for integration into supervisory control and data acquisition (SCADA) systems.
Key Features:
- Phase Overcurrent Protection (50/51): Provides instantaneous and time-delayed protection for phase faults in feeder circuits
- Ground Fault Protection (50G/51G): Detects and responds to ground faults with both instantaneous and inverse-time characteristics
- 5 A CT Input Compatibility: Supports standard 5 A current transformer secondary inputs for both phase and ground circuits
- Wide Control Power Range: Operates on 90–300 VDC or 70–265 VAC, ensuring flexibility across different power systems
- RS485 Communication Interface: Enables remote monitoring and integration with SCADA systems via 2-wire communication
- Microprocessor-Based Design: Ensures precise measurement, configurable settings, and reliable protection performance
- Frequency Compatibility: Supports both 50 Hz and 60 Hz systems for global application use
- Standard 735 Series Platform: Designed for consistency and interoperability within GE protection relay systems
The 735-5-5-HI-485 delivers the reliability and precision required for feeder protection, fault detection, and power system monitoring in industrial and utility environments.
