Application | Transformer Dissolved Gas Analyzer

As a means of insulation supervision, in the past, DC leakage, insulation resistance, dielectric loss measurement, AC breakdown voltage test, partial discharge measurement and other insulation characteristic tests were commonly used. However, the disadvantage of these tests is that the equipment under test is required to be temporarily shut down, the insulation cannot be continuously monitored, and it is difficult to detect very small internal faults before the accident. Partial discharge test is a better method to detect local insulation defects, but under the existing instrument conditions, it is often affected by external interference, especially transformers, which affect the accuracy of its detection.



The use of Transformer Oil DGA Test kit (gas chromatography) to analyze the dissolved gas in the oil of oil-filled equipment is an effective preventive test method for detecting latent faults such as overheating and discharging of oil-filled equipment such as transformers, and the equipment under test does not need to be powered off, and a small amount of oil samples are taken. Analysis can determine the hidden dangers in the operation of the equipment, the nature and severity of latent failures, etc., which can be used to predict early, prevent accidents before they occur, and ensure the safe operation of oil-filled electrical equipment is of special significance. The actual developing faults can be overhauled in a planned and economical manner, thereby avoiding equipment damage and unplanned power outages.

Dissolved gas analysis of transformer oil contributes to the economic development with its advantages.


DGA test of transformer oil can identify the relevance of equipment defects and operating conditions to ensure normal operating conditions for safe operation, such as load, temperature rise, etc., so as to prevent equipment from overheating damage.

DGA Testing of transformer can help analyze the cause of gas relay action, so as to guide the elimination of the cause of gas relay action.

For equipment that has been involved in an accident, transformer oil dga test kit is helpful to immediately understand the nature of the equipment accident and the extent of damage, so as to guide maintenance.

Dissolved gas analysis can help ensure that the newly input equipment is not damaged.


Working Principle | Transformer Dissolved Gas Analyzer

Transformer Dissolved Gas Analyzer (Gas chromatography) adopts gas chromatograph analysis technology is a separation and analysis technology for multi-component mixtures. It mainly uses the difference in the boiling point, polarity and adsorption coefficient of each component in the sample to separate each component in the chromatographic column, and qualitatively and quantitatively analyze the separated components.
The gas chromatograph uses gas as the mobile phase (carrier gas). When the sample is fed into the sample inlet and vaporized, it is carried by the carrier gas into the packed column or capillary column. Due to the boiling point, polarity and adsorption coefficient of each component in the sample The difference between each component is separated in the column, and then the detector connected to the column will detect each component in sequence according to the physical and chemical characteristics of the component, and finally transmit the data to the chromatographic workstation through the serial port or the network. , The chromatographic workstation records and analyzes the gas chromatogram of each component to obtain the analysis report of each component.
