    em resposta a: What are the typical uses for medium setting emulsion? #131047
    Plinio Arcos
    Membro

    Medium setting emulsions are designed to allow a moderate working time before the emulsion breaks and sets. They are commonly used in mixing applications where aggregates and emulsion are combined prior to placement, such as in open-graded mixes or cold recycling. The medium setting rate provides sufficient time for thorough mixing and proper coating of aggregates. These emulsions are suitable for maintenance tasks like patching, pothole repairs, and some types of cold mix asphalt, balancing workability with timely curing.

    Diesel fuel quality is tested during the polishing process by measuring key parameters such as water content, particulate concentration, and fuel cleanliness. Sensors and testing equipment monitor these factors in real-time to ensure that the fuel meets quality standards before use.

    em resposta a: What causes high voltage transformer bushing failure? #122633
    Plinio Arcos
    Membro

    Bushing failure can be caused by insulation degradation due to moisture ingress, oil leakage, thermal stress, or electrical overloading. Contaminants in the oil, mechanical damage from environmental factors like wind or seismic activity, and aging materials also contribute. Poor maintenance, improper installation, or failure to detect partial discharges early can lead to catastrophic bushing failures.

    em resposta a: What is the process of wind turbine transformer oil degassing? #122532
    Plinio Arcos
    Membro

    Wind turbine transformer oil degassing involves removing dissolved gases and moisture from the oil to prevent oxidation, improve insulation, and enhance overall performance. The process uses vacuum degassing units, which apply low pressure to the oil, causing trapped gases and moisture to evaporate. This ensures the oil remains free of contaminants, which can cause degradation and reduce the transformer’s efficiency.

    em resposta a: How do synthetic oils perform in x-ray transformers? #122445
    Plinio Arcos
    Membro

    Synthetic oils perform exceptionally well in x-ray transformers due to their superior thermal stability, oxidation resistance, and dielectric properties. They can withstand higher temperatures and are less prone to degradation compared to mineral-based oils, making them ideal for applications where long-term performance and stability are required. However, synthetic oils tend to be more expensive. GlobeCore’s oil filtration systems can be used with synthetic oils, helping to remove contaminants and extend the life of the oil, ensuring it continues to perform effectively in x-ray transformers.

    em resposta a: Which oils are compatible with x-ray systems? #122409
    Plinio Arcos
    Membro

    Oils compatible with x-ray systems are typically high-quality mineral-based or synthetic insulating oils with excellent dielectric properties and thermal stability. These oils must have a high breakdown voltage to provide effective insulation and be capable of withstanding high temperatures. Additionally, the oils should have low moisture content and resist oxidation to ensure long-term performance. GlobeCore offers filtration systems that can help maintain the quality of these oils, ensuring they remain suitable for use in x-ray systems over time.
