GE 760-P1-S5-LO-A10-G-T digital relay

760-P5-G5-S5-HI-A20-R—12


The 760-P1-S5-LO-A10-G-T is a digital relay from GE Multilin's 750/760 series, primarily used for management, protection, and control of power distribution feeders. The detailed introduction is as follows:

Model Nomenclature

  • 760: Represents the product series, i.e., GE Multilin 750/760 series feeder relays.

  • P1: Likely indicates the protection function group, typically providing basic protection capabilities.

  • S5: May represent the communication interface group, supporting more protocols or offering stronger communication capabilities compared to some other models.

  • LO: Usually denotes low-power design or logic output configuration.

  • A10: May indicate analog output configuration or parameters related to specific application scenarios.

  • G-T: Likely refers to the installation method (e.g., rail mounting) or temperature rating, suitable for a wide temperature range》


Functional Features

  • Comprehensive Protection Functions:

    • Equipped with time-overcurrent and instantaneous overcurrent protection, featuring two phase TOC elements. Each phase is equipped with a level detector, allowing setting of pickup current levels for tripping, alarming, or control, and supporting selection of 15 curve shapes.

    • Provides frequency protection, including 2 underfrequency elements and 2 overfrequency elements, etc., to protect frequency-sensitive equipment such as generators.

  • Intelligent Equipment Management:

    • Tracks the number of operations of the main circuit breaker, calculates the wear of circuit breaker contacts in each phase, and can detect circuit breaker faults and monitor trip coils, facilitating equipment maintenance and fault troubleshooting.

  • Precise Metering Functions:

    • Features accurate built-in metering capabilities, enabling comprehensive measurement of parameters including demand and energy, eliminating the need for auxiliary metering devices and reducing costs.

  • Strong Communication Capabilities:

    • Supports industry protocols such as DNP and Modbus, and may be equipped with an Ethernet port for easy integration with other systems to achieve remote monitoring and data transmission.

  • Convenient and Efficient Maintenance:

    • Equipped with functions such as IRIG-B time synchronization, event reporting, waveform capture, and data logger, which can reduce fault diagnosis time and maintenance costs. The built-in simulation function simplifies the testing process.

Technical Parameters

  • Current and Voltage Inputs:

    • Typically accepts current signals such as 5A phase CT input and 5A zero-sequence CT input, as well as voltage signals such as 100V or 120V (line voltage). Specific details should be referred to the product manual.

  • Power Supply Range:

    • Generally adapts to wide-range power fluctuations of 88-300VDC or 70-265VAC (48-62Hz).

  • Output Relays:

    • May be equipped with multiple programmable output relays for operations such as tripping, alarming, or control.

  • Analog Outputs:

    • May have several channels of 4-20mA analog outputs for remote monitoring of relevant electrical parameters.

  • Operating Temperature:

    • The operating temperature range is typically -20°C to +60°C, which may vary according to the model suffix.


Application Scenarios

  • Provides primary protection and control for power distribution feeders in solidly grounded, high-impedance grounded, or resonant grounded systems.

  • Suitable for busbar interlocking schemes, load shedding schemes based on voltage and frequency factors, etc.

  • Can serve as backup protection for transmission lines, feeders, and transformers, and can also be used for interconnection protection of distributed generation (DG).
