  • Sulfur Dioxide Gas Detectors | SO2 Detectors | Industrial

    Sulfur Dioxide Gas Detectors (SO2 Detectors) Sulfur dioxide (SO2) is a colorless, extremely toxic gas with a strong odor. Common applications of sulfur dioxide include sulfuric acid production, pulp and paper mills, chemical processing, food and beverage, coking operations and petroleum refineries. Since coal and petroleum often contain sulfur compounds, their combustion will generate SO2 unless the sulfur compounds are removed before the fuel is burned.

  • Transformer Maintenance - PDHonline.com

    For example, if your transformer tested 0.1%, you need to go to 0.3% by adding 0.2% of the total weight of the transformer oil. The nameplate gives the weight of oil—say 5,000 pounds—so 5,000 pounds X 0.002 = 10 pounds of DBPC needs to be added. It’s ok if you get a little too much DBPC; this does not hurt the oil.

  • Transformer Diagnostics and Condition Assesment

    Jun 19, 2017 · A fault detector equipped with a data logger can be used to detect internal partial discharge, arcing, sparking, pump impeller and bearing problems. This test is also useful in pinpointing mechanical noises and loose parts (blocking, deflectors, etc.). Care should be taken because this method requires contact with the transformer while energized.

  • Using Dissolved Gas Analysis to Detect Active Faults in Oil

    Dissolved gas-in-oil AnalysisGases Detected and Their RelevanceExample 1Example 2Example 3Dissolved gas-in-oil analysis, performed in accordance with ASTM D3612 or IEC 60567, is by far the most frequently requested diagnostic test and the single most important test performed on transformer oil. As the insulating materials of an electrical apparatus, such as a transformer, break down from excessive thermal or electrical stress, gaseous byproducts form. The byproducts are characteristic of the type of incipient-fault condition, the materials involved and the severity of the condition. Indeed, it is the ability to detect such a variety of problems that makes this test such a powerful tool for detecting incipient-fault conditions and for root-cause investigations after failures have occurred. Dissolved gases are detectable in low concentrations (ppm level), which usually permit early intervention before failure of the electrical apparatus occurs, and allow for planned maintenance. The DGA technique involves extracting or stripping the gases from the oil and injecting them in...
