F31X134EPRBAG1 | GE Protection Stock

Description

Product Introduction

This GE F31X134EPRBAG1 is a protection relay board for GE’s excitation and power conversion control platforms. The “EPR” designation identifies this as an Excitation Protection Relay board, providing fault detection and trip coordination for generator and excitation systems.

The board monitors generator and excitation system parameters—voltage, current, frequency, and temperature—and initiates protective actions when fault conditions are detected. It provides relay outputs for tripping breakers, annunciating alarms, and coordinating with other protection devices. The board includes fault logging for post-event analysis.

Key Technical Specifications

Key Selling Points & Differentiators

• Comprehensive Protection: Provides essential protection functions for generator excitation systems including overvoltage, undervoltage, and loss of excitation.
• Fault Logging: Onboard memory logs fault events for post-event analysis and troubleshooting.
• Relay Outputs: Multiple relay outputs for tripping breakers, annunciating alarms, and coordinating with other protection devices.
• Quantified Testing Protocol: We test all protection functions for accurate setpoint response and verify relay outputs under simulated fault conditions.
• Warranty & Support: 2-year functional warranty. We provide protection setting guidance and application support.

Frequently Asked Questions (FAQ)

Q1: What protection functions does the EPRBAG1 provide?

A: The board provides overvoltage, undervoltage, overcurrent, and loss of excitation protection. Additional functions may vary by configuration. Consult your system documentation for the specific functions available.

Q2: Does the board have programmable protection setpoints?

A: Yes, the protection setpoints are programmable through the system configuration. The specific setting ranges depend on the application and system voltage/current ratings.

Q3: Are the relay outputs normally open or normally closed?

A: The relay outputs are typically dry contacts configurable as normally open or normally closed, depending on the application requirements. Verify the specific configuration for your system.

Q4: Does the board log fault events?

A: Yes, the board includes onboard memory for fault logging. Fault events are stored with a timestamp for post-event analysis and troubleshooting.

Q5: What is the lifecycle status of the EPRBAG1?

A: This board is discontinued. We have a limited quantity of new surplus units. Used pulls are occasionally available. If your protection system requires this board, we recommend securing a spare.
