Product Description

Transformer Oil Chromatograph Analysis Gas Chromatograph Unit DGA 

Product Presentation

GC-9760A Transformer Oil Portable Chromatograph is one of our newest portable gas chromatographs for on-site rapid analysis, integrating chromatographic detection, analysis and diagnosis. Set micro-detector, mini gas source, built-in touch screen computer in one, more integrated than the traditional portable oil chromatography, stability and stability.
Chromatography integration is higher, stability and good, more compact appearance, more convenient operation. On-site analysis, can be timely analysis and diagnosis of transformer fault conditions.
The instrument adopts the classic three-detector process, the analysis data and the traditional laboratory chromatograph data is completely consistent. The instrument adopts advanced small modular design concept, high degree of integration of the whole machine, small volume, light weight, easy to carry to the scene for analysis, for the supervision and testing of the transformer to provide timely and accurate data at the same time save a lot of manpower and material resources.



What is the classic three-detector process

The classic three-detector process of Transformer Oil Chromatograph includes a UV detector, a Fluorescence detector, and an Infrared detector. These detectors are used to analyze the chemical composition of transformer oil and to detect any potential contaminants or degradation products.

Here's a brief explanation of each detector's role in the process:

1. UV detector: The UV detector is used to detect aromatic hydrocarbons present in the transformer oil, such as benzene, toluene, and xylene. The oil sample is irradiated with UV light, and the hydrocarbons absorb the light at specific wavelengths. The detector measures the amount of light absorbed, and this data is used to determine the concentrations of the hydrocarbons in the oil.

2. Fluorescence detector: The fluorescence detector is used to detect compounds that fluoresce when exposed to UV light. This includes contaminants such as polycyclic aromatic hydrocarbons (PAHs) and oxidation products, such as quinones. The oil sample is exposed to UV light, and the detector measures any fluorescence emitted by the sample. The intensity of the fluorescence is proportional to the concentration of the fluorescing compounds in the oil.

3. Infrared detector: The infrared detector is used to detect aliphatic hydrocarbons present in the transformer oil, such as alkanes and alkenes. The oil sample is passed through an infrared cell, where it is exposed to infrared radiation. The hydrocarbons in the oil absorb the radiation at specific wavelengths, and the detector measures the amount of radiation absorbed. This data is used to determine the concentrations of the hydrocarbons in the oil.

By analyzing the data from all three detectors, the Transformer Oil Chromatograph can provide a detailed analysis of the chemical composition of the transformer oil, which can be used to monitor the transformer's condition and identify any potential issues that may require maintenance.
