Measurement and analysis of gases dissolved in transformer oil
Dissolved gas analysis, the DGA
Power transformerThe dissolved gas analysis (DGA) is based on the state maintenance (CBM) and identify transformer fault and prevent accidental outage of critical components.Level of gases in the transformer oil can indicate the fault, the rate can be used to determine the level of its severity.
The DGA including the main fault in the gashydrogen, methane, ethane, ethylene, acetylene, carbon monoxide and carbon dioxide.
The advantages of visa, the DGA monitoring system
Visa, Optimus used vacuum gas extraction technology, compared with the traditional at the top of the space and other separation methods, can extract more thoroughly dissolved gas.This will lead to more accurate and reliable results, has nothing to do with the oil type, life or total dissolved gas.
For the actual gas measurement, monitoring system using infrared (IR) gas sensing technology, including visa, tunable infrared filter allows a wider range of infrared scanning, can provide better gas selectivity.The measurement integrated a vacuum infrared reference benchmark, can use continuously in order to reduce the intensity of light source such as the mechanism of drift.Allow us to all of these in the need for maintenance or maintenance achieve the long-term stability and performance measurement.
The advantages of visa, the DGA monitoring technology
The stability of
High gas extraction rate, vacuum infrared reference method and the automatic calibration makes the results more reliable and has higher long-term stability.
The service life is long
Through the solid design and implementation of the processing system of oil and gas sealing metal structure maintenance free operation.
Optical infrared measurement module with no moving parts.
There is no material no gas cylinders.
The out-of-the-box performance
On-line DGA monitoring provide the condition of transformer real-time view.
Support take timely corrective actions.
