Introduction

Main Functions

Continuous on‑line monitoring of dissolved gas and moisture in oil: Real‑time measurement of fault characteristic gases including hydrogen and carbon monoxide, as well as moisture content in insulating oil. Hydrogen indicates overheating and partial discharge faults; carbon monoxide signals overheating and degradation of insulating paper.
Multi‑sensor extended acquisition: Supports external sensors for top / bottom tank oil temperature, transformer load, ambient temperature, etc. Correlates operating conditions with DGA readings for comprehensive transformer condition analysis.
On‑board diagnostic calculation compliant with IEEE standards: Embedded IEEE‑based transformer mathematical models process raw measurement data and deliver transformer health evaluation and fault trending, instead of only collecting raw data.
Fault early warning and alarm output: Triggers local alarms when gas or moisture thresholds are exceeded. Detects incipient faults such as partial discharge and insulation aging in advance to prevent catastrophic failures and unplanned outages.
Multi‑protocol data communication & upload: Supports Modbus, DNP3.0, multi‑mode optical fiber and other interfaces. Raw data and diagnostic results can be uploaded to substation SCADA and condition‑monitoring back‑end systems for remote supervision.
Hardware self‑diagnosis: Built‑in self‑test for sensors, power supply and communication links. Reports device internal faults for convenient maintenance troubleshooting.

Applications

This equipment is designed for on‑line condition monitoring of oil‑immersed power transformers. It is widely applied in substations, thermal power plants, combined‑cycle power stations and industrial captive power plants for main transformers and station‑service transformers.

Tracks fault gas and moisture variation in transformer insulating oil 24/7, partially replacing offline oil chromatography sampling tests.
Provides early warning of incipient internal transformer faults including partial discharge, winding overheating and paper insulation degradation, enabling predictive maintenance and reducing unplanned power outages.
Evaluates transformer health and service life by combining oil temperature and load data to support maintenance decision‑making.
Compatible with mineral insulating oil, natural ester fluid and synthetic ester fluid. Used for retrofitting existing transformers and new‑build projects, also available as replacement spare parts.
