Hydran M2 Online Transformer Monitoring System
The Hydran M2 is a cutting-edge online monitoring solution specifically designed for power transformers, enabling real-time detection of incipient faults to prevent unplanned outages, extend equipment lifespan, and optimize maintenance strategies. It integrates advanced sensor technology, data analytics, and remote connectivity to deliver actionable insights into transformer health.


Core Monitoring Parameters
Dissolved Gas Analysis (DGA)
Continuously measures key fault gases (e.g., H₂, CH₄, C₂H₂, C₂H₄, C₂H₆, CO, CO₂) in transformer oil, detecting overheating, arcing, and partial discharge at early stages.
Oil Condition Monitoring
Monitors oil temperature, moisture content (water activity), and dielectric strength to assess oil degradation and insulation performance.
Partial Discharge (PD)
Detects and locates partial discharge activity— a critical precursor to insulation failure—using ultra-sensitive sensors and signal processing algorithms.
Load & Environmental Data
Captures load current, ambient temperature, and humidity to correlate operational conditions with transformer health trends.
Key Features & Benefits
Real-Time Data & Alerts
- 24/7 continuous monitoring with instant notifications (via email, SMS, or SCADA) for abnormal conditions.
- Configurable alarm thresholds tailored to specific transformer types and operational requirements.
Advanced Analytics
- AI-driven fault diagnosis to classify fault types (e.g., thermal, electrical) and estimate severity.
- Trend analysis and predictive modeling to forecast maintenance needs and avoid catastrophic failures.
Remote Access & Integration
- Web-based dashboard for secure remote access to real-time data, historical records, and reports.
- Seamless integration with existing SCADA, DMS (Distribution Management Systems), or CMMS (Computerized Maintenance Management Systems).
Robust Design
- IP65-rated enclosure for harsh outdoor environments (resistant to dust, moisture, and temperature extremes).
Low power consumption and redundant power supply options for reliable long-term operation.
