PHM of Transformer

Prognostics and Health Management for oil-immersed transformers. BHP PHM of Transformer is an advanced online monitoring and intelligent diagnostic system purpose-built for oil-immersed power transformers.

By integrating multiple sensor technologies, the system continuously tracks transformer health status, enabling early fault detection, predictive maintenance, and extended asset service life.

Key Monitoring Dimensions

Multiple sensor technologies work together to give a continuous view of insulation, mechanical, thermal, and oil chemistry conditions.

Partial Discharge (PD) - real-time detection of insulation degradation and discharge activity
Vibration Analysis - mechanical condition monitoring of windings and core
Acoustic Emission (Noise) - anomaly detection through sound signature analysis
Ambient Temperature and Humidity - environmental tracking for operational context
Infrared Thermography - thermal imaging for hotspot identification
Visible Light Imaging - visual inspection of external physical conditions
Dissolved Gas Analysis (DGA) - oil chromatography for key fault gases (H2, CH4, C2H2, C2H4, CO, CO2)
Core Grounding Three-Phase Current - core grounding health and circulating currents

Key Benefits

Early detection of incipient faults extends transformer service life and reduces unplanned outages and catastrophic failures. Condition-based maintenance also minimizes unnecessary inspections.

Centralized data visualization with real-time alarm notifications supports IEC 61850 and DNP3 protocols for seamless SCADA integration.

Target Applications

PHM of Transformer is designed for transmission and distribution transformers in utility substations, industrial facilities, renewable energy plants, data centers, and hospitals.

Continuous multi-sensor monitoring gives operators a single view of asset health so maintenance can be planned before a failure occurs.
