GE Energy Hydran M2 Mark III monitoring equipment

Gas Detection Parameters   

• Detectable Gas Types: It can detect three key gases, namely hydrogen (H₂), carbon monoxide (CO), and acetylene (C₂H₂). The generation and content changes of these gases can reflect the internal faults of the transformer.

• Detection Range

  • Hydrogen (H₂): 0 – 2000 ppm (parts per million by volume).

  • Carbon monoxide (CO): 0 – 5000 ppm.

  • Acetylene (C₂H₂): 0 – 200 ppm.

• Detection Accuracy

  • Hydrogen (H₂): ±5% of the reading or ±2 ppm, whichever is greater.

  • Carbon monoxide (CO): ±5% of the reading or ±5 ppm, whichever is greater.

  • Acetylene (C₂H₂): ±5% of the reading or ±1 ppm, whichever is greater.

Performance Parameters

• Response Time

  • T₉₀ (the time required to reach 90% of the final measured value): Approximately 3 hours for hydrogen; approximately 6 hours for carbon monoxide; approximately 8 hours for acetylene.

• Repeatability: Better than ±3%.

• Zero Drift: Less than ±1% of the full – scale range per month.

• Span Drift: Less than ±1% of the full – scale range per month.

Operating Condition Parameters

• Operating Temperature: -20°C to +55°C, capable of adapting to a wide range of ambient temperatures.

• Relative Humidity: 0 – 95%, non – condensing, able to work stably under different humidity conditions.

• Storage Temperature: -40°C to +70°C.

Electrical Parameters

• Power Supply Requirements: 100 – 240 VAC, 50/60 Hz, suitable for different power supply environments.

• Power Consumption: Approximately 15 VA maximum.

Physical Parameters

• Dimensions: Approximately 220mm (width) × 330mm (height) × 160mm (depth).

• Weight: Approximately 4.5 kg.
