Why Choose a Portable Transformer Oil Chromatograph?

A portable transformer oil chromatograph is a high-tech instrument specifically designed for on-site gas chromatographic analysis of insulating oil in power transformers and other oil-filled electrical equipment (such as reactors, instrument transformers, and bushings).
Its core purpose is to detect fault-characteristic gases dissolved in oil, diagnose potential internal faults, and serve as a key tool for condition-based maintenance (CBM) and preventive testing in the power industry.

Key Concerns for Users:

1.Accuracy and Reliability of Analysis

Our device adopts the classic “three-detector process,” completing full analysis of seven dissolved gases (H₂, CH₄, C₂H₄, C₂H₆, C₂H₂, CO, CO₂) in a single injection. The results are highly consistent with those from laboratory-grade chromatographs, with qualitative deviation ≤1% and quantitative deviation ≤3%, ensuring precise and trustworthy data.

2.Portability and Rapid Deployment
With an advanced compact modular design, the instrument weighs less than 15 kg and comes with a trolley case, making it easy to carry to field sites. It provides timely, accurate data for transformer inspections while saving substantial manpower and time.

3.Intelligent and User-Friendly Operation
A fully computerized touch-screen interface allows real-time monitoring of temperature and carrier-gas flow across four channels. Parameters are set with one touch, and users only need simple power-on/off operations to perform routine testing, greatly reducing the operating threshold.

4.Stability and Protection Functions
The system features multiple safeguards: automatic bridge-current cutoff when pressure or flow exceeds preset limits, protection of the thermal-conductivity detector in case of carrier-gas loss, and automatic shutdown with fault alerts if temperature control fails—ensuring long-term stable operation.

5.Networking and Data Management
Built-in 10/100 M adaptive Ethernet enables fast remote data transmission. The dedicated chromatograph workstation for power systems supports centralized management of multiple devices, providing trend analysis, over-limit alarms, three-ratio diagnostics, and more to help O&M teams make informed decisions.
