  • Advantages and disadvantages of solid state transformer

    Smart solid state transformers are far more effective devices with a number of advantages. The first and most important one is that they are energy efficient. This means that they can deliver much more power through similar wires at a faster rate. It is estimated that their power transmission capability is 10 times greater than the traditional transformers.

  • 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...
