Hydran M2 | GE Transformer Monitoring Device HYDRANM2

Hydran M2 Transformer Monitoring Device

Overview
The Hydran M2 is an advanced, compact, and permanently mounted on-line transformer monitoring device designed to detect and alert personnel to developing fault conditions in transformers. It monitors fault gases (hydrogen and composite gases), moisture in oil, and can be further enhanced with additional sensors to track transformer performance based on established standards.

Features

• Gas Monitoring:

  • Monitors hydrogen (general fault gas) and composite fault gases (including hydrogen and carbon dioxide).
  • Measures moisture in oil in terms of %RH and ppm.

• Sensor Integration:

  • Can accommodate additional sensors (e.g., load, oil temperature).
  • Provides an option to process transformer mathematical models based on IEC® and IEEE® standards for advanced performance analysis.

• Installation:

  • Easily installed on a single valve with no moving parts, pumps, or extra piping.
  • No field calibration required.

• Alarms and Diagnostics:

  • Local and remote alarms set at predefined levels to alert operators of potential issues.
  • Self-test and self-diagnostics to ensure proper functioning.

• Data Logging:

  • Logs data and significant events for up to one year.

• User Interface:

  • Comes with user-friendly client/server graphical software for data analysis and monitoring.

Communication and Integration

• Communication Methods:

  • RS485 output is standard, with options for TCP/IP (copper or fiber) for flexibility in integration with existing systems.

• Input/Output Cards:

  • Choice of up to 4 input or output cards for customized system requirements.

• Vacuum-Resistant Membrane:

  • Equipped with a vacuum-resistant gas extraction membrane to maintain reliable readings over time.

Applications

• Medium to Large-Sized Transformers:
  Ideal for use in medium to large transformers with lower risk or consequence of failure.

• Transmission Transformers:
  A significant upgrade from manual oil sampling methods, offering real-time monitoring for improved transformer health management.

Benefits

• Real-time Monitoring:
  Continuous monitoring of hydrogen or composite fault gases and moisture in oil.

• Enhanced Transformer Management:
  Helps in assessing transformer performance based on established industry standards and provides valuable insights into operational efficiency.

• Preventive Maintenance:
  Early detection of faults leads to improved preventive maintenance, reducing the risk of unexpected failures and extending transformer lifespan.
