九月 15, 2025 7:43 上午 回复至： What is online DGA for transformers and do I still need purification? #325393
Online DGA sensors monitor gases in real time. But they depend on oil quality. If oil is contaminated, data is skewed. GlobeCore systems maintain clean oil, ensuring your DGA monitoring works correctly.
Bituminous emulsion is a mix of bitumen, water, and emulsifiers used in roadworks, waterproofing, and cold asphalt mixes. GlobeCore serves both municipal and industrial clients with turnkey emulsion production plants designed for flexibility, reliability, and scalability.
Collect a sample, perform BDV, DGA, and tan delta tests. Before testing, treat oil using GlobeCore’s purification and dehydration machines to remove water and particles that might lower test values or cause misleading results.
Mobil Turbine Oil 46 is a medium-viscosity lubricant used in industrial and power turbines requiring balanced cooling and film strength. GlobeCore regeneration units clean and degas 46-grade oils, extending operational life.
Turbo 32 oil is a medium-viscosity turbine lubricant designed for compressors and light turbines. GlobeCore purification units remove moisture and contaminants, keeping Turbo 32 effective over extended use.
八月 3, 2025 8:26 上午 回复至： What are the types of cooling in transformers and how does oil fit in? #323622Transformers use cooling types like ONAN (oil natural air natural), ONAF (oil natural air forced), and OFAF (oil forced air forced), all involving insulating oil. GlobeCore systems maintain these oils to ensure effective heat transfer and insulation.
Recycled transformer oil is aged or used oil that has been processed to remove acids, sludge, water, and gases. GlobeCore regeneration plants restore recycled oils to near-new quality, allowing safe reuse in transformers and reducing waste.
Nynas Nytro Bio 300X is a sustainable insulating fluid that combines biodegradability with strong electrical stability. GlobeCore regeneration units dry and purify Nytro Bio 300X, ensuring consistent performance and lowering operating costs.
七月 31, 2025 12:07 下午 回复至： How does a hermetically sealed type transformer differ from conventional units? #323198Hermetically sealed transformers use sealed tanks to minimize oxidation and moisture contamination, extending oil life. GlobeCore filtration units help maintain oil quality even in these sealed systems by treating the fluid during servicing.
ASTM D3487 Type II defines the requirements for inhibited mineral transformer oils, including dielectric strength and oxidation stability. GlobeCore purification plants treat oils to meet or exceed ASTM D3487 Type II standards for power systems.
Rapid setting emulsion is a cationic bitumen emulsion formulated to break quickly on contact, ideal for tack coats and road surface treatments. GlobeCore plants provide reliable production of rapid-setting emulsions with consistent properties.
Slow setting bitumen emulsion is designed for applications where longer working time is needed, such as soil stabilization and priming. GlobeCore plants produce these emulsions with customizable breaking times and stability.
The cost of GlobeCore portable silicone oil breakdown voltage testers varies by configuration, but they save significant expenses by preventing equipment damage.
The most efficient way to test transformer oil breakdown voltage is by using a portable tester like the GlobeCore TOR-80, which delivers precise results on-site in minutes.
七月 23, 2025 10:28 上午 回复至： How accurate are multifunctional testers for mineral transformer oil? #322043GlobeCore TOR-7 delivers laboratory-grade precision, ensuring every parameter — from moisture to dielectric strength — meets IEC and ASTM standards.
The GlobeCore TOR-7 functions as a mobile field kit for FR3 fluid testing, ideal for on-site maintenance teams and substations.
GlobeCore TOR-7 delivers laboratory-grade accuracy, ensuring precise measurements of moisture, contamination, dielectric strength, and tan delta.
If you’re interested in biodiesel production and the use of mutton fat as a feedstock, it’s important to consider its properties compared to other animal fats and plant oils. Mutton fat can provide unique fatty acid profiles that may influence biodiesel quality, such as cetane number and cold flow properties. Its availability can vary significantly based on local agricultural practices and meat industry byproducts. Additionally, the cost-effectiveness of using mutton fat hinges on regional supply chains and processing capabilities. Utilizing advanced equipment like GlobeCore’s biodiesel plants allows for efficient conversion of diverse feedstocks, including mutton fat, into sustainable energy solutions while optimizing production costs. If you have specific questions or areas of interest regarding biodiesel or equipment used in its production, feel free to ask!
The most effective extraction methods for walnut oil while preserving quality are cold pressing and expeller pressing. These mechanical techniques avoid high temperatures that degrade oil quality, retaining the optimal fatty acid profile for biodiesel. For larger-scale production, solvent extraction using hexane increases yield but requires post-processing to remove residual solvent. Pre-cleaning and drying the walnuts improve oil clarity and reduce moisture. Once extracted, the oil can be processed in the GlobeCore USB biodiesel plant, which preserves its chemical integrity during conversion.
Key tests for Jatropha biodiesel include: viscosity, cetane number, acid value, cloud point, pour point, oxidation stability, and ester content. These ensure compliance with ASTM D6751 or EN 14214 standards. Jatropha biodiesel generally performs well in these tests, though cold flow properties (cloud/pour point) may need improvement via additives or blending. The GlobeCore USB plant produces biodiesel that consistently meets quality parameters through controlled transesterification, moisture removal, and precise chemical dosing—ensuring clean, engine-safe fuel.
