To optimize energy transmission, reduce losses, manage voltage tiers, and interconnect grid segments.
January 22, 2026 at 4:05 am in reply to: Why is air in the oil hoses a safety concern, and how does the TSS address it? #331145伊藤 聡太郎MemberAir trapped in oil hoses can create misleading signals to protective devices, potentially triggering false shutdowns or gas relay trips. To mitigate this, the TSS incorporates an air relief valve that releases trapped air, preventing false alarms while maintaining reliable protective operation during oil treatment.
January 22, 2026 at 3:46 am in reply to: What does a tan delta test PDF explain for power transformers? #331139伊藤 聡太郎MemberIt explains dielectric loss measurements, test setup, acceptance criteria, trending, and how insulation degradation, moisture, or contamination influence tan-delta values.
January 22, 2026 at 12:20 am in reply to: What role does an electric power transformer play in voltage step-up and step-down? #331091伊藤 聡太郎MemberIt changes AC voltage levels while maintaining power balance (minus losses) through magnetic induction.
January 20, 2026 at 6:46 pm in reply to: What are typical power transformer failure statistics? #330644伊藤 聡太郎MemberFailures are often linked to insulation aging, moisture ingress, OLTC issues, and bushings; utilities track DGA and incident data to estimate MTBF ranging from decades to half-century for well-maintained units.
伊藤 聡太郎MemberEaton power transformers serve transmission and distribution utilities, industrial plants, commercial buildings, mining sites, oil and gas facilities and infrastructure such as airports and hospitals. They are integrated into switchgear lineups and substation packages. Industries that require reliable medium and high voltage equipment, conformity to regional standards and comprehensive service networks tend to choose such established brands. Eaton also supports specialized segments like marine, data centers and microgrids with tailored transformer solutions.
伊藤 聡太郎MemberThe UVB-6 and UVB-10 plants are suitable for medium-scale emulsion production with automatic water-bitumen ratio control and colloid milling.
November 12, 2025 at 3:49 am in reply to: Would like to know more about the unit, its maintenance, ability to handle modified emulsion preparation with latex, production rate, and general performance. #327563伊藤 聡太郎MemberThe bitumen emulsion plant supports latex and polymer incorporation for modified emulsions. Maintenance involves routine cleaning of the colloid mill and dosing lines. Production rate ranges from 4 to 25 t/h depending on configuration.
November 10, 2025 at 6:19 pm in reply to: Request for technical information on the CMM-R online oil regeneration system for use in transformer maintenance and energy sector services. #327434伊藤 聡太郎MemberThe CMM-R series performs continuous regeneration of transformer oil while equipment remains energized. It removes acids, moisture, and oxidation products. Technical specifications and process diagrams will be provided.
伊藤 聡太郎MemberThe CMM-8LT transformer oil purification unit ensures removal of moisture and gases down to 10 ppm and 0.1 % vol respectively. A full technical and commercial offer will be provided upon request.
伊藤 聡太郎MemberThe process involves heating, coarse filtration, vacuum dehydration, fine filtration, and degassing. GlobeCore automates each stage in their purification systems, ensuring restored ISO cleanliness codes and prolonged oil life for transformers and hydraulics.
September 15, 2025 at 7:02 am in reply to: ¿Cuál es la función de un equipo de filtrado de aceite profesional? #325377伊藤 聡太郎MemberLos equipos de GlobeCore están diseñados para trabajar con aceites industriales contaminados por agua, partículas o gases. Sus sistemas son móviles o estacionarios, adaptables a distintas viscosidades y con controles automáticos para operación continua.
September 10, 2025 at 11:37 am in reply to: What is an industrial hot air dryer machine and where is it used? #325169伊藤 聡太郎MemberThese machines are used in manufacturing and power engineering for drying transformer windings and insulation. GlobeCore integrates hot air drying into their transformer service solutions – especially after oil draining or repair.
September 9, 2025 at 3:51 pm in reply to: What does transformer operation and maintenance involve? #325013伊藤 聡太郎MemberIt includes regular inspections, oil analysis (DGA, BDV), temperature control, and purification. GlobeCore supports this with mobile units for oil regeneration and monitoring tools – helping operators extend transformer lifespan and avoid unplanned outages.
September 9, 2025 at 8:27 am in reply to: What makes a transformer oil filtration machine by GlobeCore unique? #324821伊藤 聡太郎MemberGlobeCore’s transformer oil filtration machines feature multi-stage degassing chambers, high-precision sensors, and remote control options. Their systems ensure moisture removal <10 ppm and BDV >70 kV, helping utilities and OEMs maintain reliable insulation in high-voltage transformers.
August 2, 2025 at 8:26 am in reply to: What is silicone transformer fluid and how is it maintained? #323478伊藤 聡太郎MemberSilicone transformer fluid is a non-flammable dielectric liquid designed for high fire safety and thermal stability in transformers. GlobeCore purification units degas and dry silicone fluids, keeping their insulating properties intact over long service intervals.
August 1, 2025 at 1:46 pm in reply to: What are typical oil filled transformer sizes and how are they maintained? #323366伊藤 聡太郎MemberOil filled transformers range from small distribution units to multi-megawatt power transformers, all using insulating fluids for cooling and protection. GlobeCore regeneration plants process oils of any volume, ensuring they stay clean and compliant with standards.
August 1, 2025 at 8:46 am in reply to: What is the difference between oil and dry type transformers? #323322伊藤 聡太郎MemberOil type transformers use mineral or ester fluids for cooling and insulation, while dry type transformers rely on air and solid insulation, offering greater fire safety indoors. GlobeCore equipment supports oil type transformers by purifying and regenerating their insulating fluids.
July 30, 2025 at 6:59 am in reply to: What is Biotemp transformer oil and why is it preferred? #322996伊藤 聡太郎MemberBiotemp transformer oil is favored for its renewable base and high flash point, reducing fire and environmental risks. GlobeCore purification plants ensure Biotemp retains its dielectric properties by filtering and drying the fluid regularly.
伊藤 聡太郎MemberThe best transformer oil depends on application, with options including mineral oils, synthetic esters (Midel), and natural esters (FR3). GlobeCore systems handle all these fluids, ensuring each maintains maximum dielectric performance.
