Description

GE MVAX31S1DE0754A

Technical Specifications:

  • Series: GE/Alstom MVAX31
  • Type: Monitoring relay module
  • Manufacturer: GE Energy / Alstom Grid
  • Application: Substation protection and monitoring
  • Operating Temperature: Industrial substation environment range
  • Mounting: Rack or panel mount in protection relay cabinets

Functional Features:

  • Provides voltage monitoring and protection functions in substation environments
  • Integrates with GE/Alstom protection relay architectures
  • Supports diagnostic and status monitoring functions
  • Designed for high reliability in power system applications
  • Modular construction for easy maintenance and replacement

Application Scenarios:

  • Substation protection and control systems
  • Medium and high-voltage power network monitoring
  • Power generation facility protection schemes
  • Industrial power distribution protection

Performance Parameters:

  • Industrial-grade reliability for continuous substation operation
  • Compatible with GE/Alstom protection relay ecosystems
  • Supports standard substation communication and interface requirements

Material and Structural Characteristics:

  • Industrial-grade PCB with high-reliability components
  • Metal or reinforced housing for EMI shielding
  • Plug-in module design for rack-based protection cabinets
  • Connector interfaces for field wiring and inter-module communication

Working Principle: The module monitors electrical parameters (such as voltage) from the substation’s measurement circuits. When parameters deviate from configured thresholds, the relay initiates protective actions or alarms, communicating status to the substation automation system. Installation Requirements:

  • Install in a designated slot within a GE/Alstom protection relay rack
  • Connect voltage and status inputs per substation schematics
  • Configure relay settings using GE configuration tools
  • Verify proper grounding and shielding

Usage Notes:

  • Confirm compatibility with the specific MVAX system version
  • Follow lockout/tagout procedures during installation and maintenance
  • Periodically test relay functions using protection test equipment
  • Replace only with compatible MVAX series modules
