January 27, 2026 at 2:38 pm in reply to: What is the role of a transformer at an electrical power station? #332269Maria FernandezMember
Step-up for transmission efficiency, auxiliary feeds, and grid interface functions.
January 26, 2026 at 4:57 am in reply to: which of these does a transformer change voltage current energy power? #331975Maria FernandezMemberA transformer changes voltage and current levels while transferring energy from one circuit to another through electromagnetic induction. It does not create energy or power; instead, it shifts the voltage/current ratio so that the apparent input power is approximately equal to the output power, minus real-world losses.
January 24, 2026 at 11:03 am in reply to: How is the power rating of a transformer calculated? #331655Maria FernandezMemberSame method, with PF-independent apparent power guiding specification.
January 23, 2026 at 3:15 pm in reply to: What do power transformer pictures reveal about construction and cooling? #331492Maria FernandezMemberPictures reveal whether the transformer is oil-filled or dry-type, the number and arrangement of radiators or cooling fins, presence of fans or pumps, and whether there is a conservator tank or sealed tank design. Bushing size and geometry hint at voltage levels, while OLTC compartments and cable boxes show connection types. Placement of temperature gauges, oil level indicators, and monitoring sensors can also be seen, giving clues about how cooling and condition monitoring are implemented.
January 22, 2026 at 8:51 am in reply to: What typical reduction in moisture content can be achieved with the CMM-12R oil regeneration systems? #331213Maria FernandezMemberThe moisture content in oil can be reduced significantly, often from the tens of ppm range down to single-digit ppm levels, enhancing dielectric performance and reducing the risk of hydrolysis.
January 22, 2026 at 2:35 am in reply to: What documentation or training is typically provided with the CMM-G? #331123Maria FernandezMemberWhile the webinar would detail operation and safety training, the unit typically comes with comprehensive manuals, on-site commissioning support, and operational training for technicians to ensure correct use of modes, maintenance planning, and safe handling of pressurized fluids.
January 21, 2026 at 11:05 am in reply to: Will the TOR-5 online monitoring system help improve DGA parameters if they increase during operation? #330876Maria FernandezMemberIn practice, TOR-5 can help stabilize or slow down the growth of some DGA parameters, but it is not a direct “gas treatment” system. By continuously drying the oil and limiting moisture-driven aging, it reduces hydrolytic reactions and secondary gas generation over time. This often leads to slower hydrogen growth and more stable trends. However, if DGA increases are caused by an active electrical or thermal fault, TOR-5 will not eliminate it – it will only help you detect it early and prevent secondary degradation.
January 19, 2026 at 8:50 pm in reply to: Why do power transformers require specific power cable ratings? #330404Maria FernandezMemberCable ratings must match kV class, ampacity, short-circuit withstand, and thermal characteristics to ensure safe operation and compliance with grid standards.
November 12, 2025 at 7:04 pm in reply to: Interested in compact bitumen emulsion sprayer and smaller models if available. #327645Maria FernandezMemberCompact emulsion sprayers are available from 200 to 1000 L capacity with manual or automatic controls. Smaller portable models can also be supplied.
November 12, 2025 at 6:47 pm in reply to: Require regular bulk bitumen supply for the Bangladesh market with CnF Chittagong pricing. #327643Maria FernandezMemberBulk supply of paving-grade bitumen is available for international delivery. Pricing depends on volume, grade, and current port rates.
November 9, 2025 at 6:42 pm in reply to: Interested in installing a vacuum chamber for use in transformer manufacturing and would like contact for further discussion about the project. #327326Maria FernandezMemberGlobeCore produces vacuum chambers and drying systems for transformer manufacturing. Please provide required dimensions and process parameters, and we’ll assign a technical representative to assist with your project.
November 9, 2025 at 3:02 pm in reply to: Looking for pricing on the CMM-4 mobile unit for transformer oil processing, to be delivered domestically. #327312Maria FernandezMemberThe CMM-4 mobile transformer oil purification unit operates at 4 m³/h and performs heating, degassing, and fine filtration. We’ll send our best pricing and delivery time estimate.
November 8, 2025 at 6:34 pm in reply to: I am looking for an oil treatment plant of 10,000 L/h capacity. #327234Maria FernandezMemberGlobeCore manufactures oil purification plants up to 12,000 L/h. For your requirement, we recommend the CMM-10 model, which performs vacuum dehydration, degassing, and fine filtration. We will send technical and pricing details.
September 17, 2025 at 2:10 pm in reply to: How does a transformer oil filtration system work? #325607Maria FernandezMemberIt heats oil, removes solid impurities, then applies vacuum dehydration and degassing. GlobeCore’s systems automate this – restoring BDV, removing acids, and bringing oil back to IEC 60422-compliant condition.
September 17, 2025 at 12:13 pm in reply to: What is the correct transformer vacuum oil filling procedure? #325584Maria FernandezMemberOil is dehydrated and degassed, then filled under vacuum to prevent moisture absorption. GlobeCore equipment automates this procedure – ensuring the oil enters the transformer with <10 ppm moisture and no entrapped gases.
September 10, 2025 at 2:07 pm in reply to: ¿Qué ventajas ofrece un filtro prensa para aceite en procesos industriales? #325244Maria FernandezMemberEl filtro prensa de GlobeCore permite separar sólidos finos del aceite en procesos de prefiltrado. Se utiliza como etapa previa a la desgasificación y secado profundo, mejorando la eficiencia general del sistema de purificación.
September 10, 2025 at 1:15 pm in reply to: What does dry type transformer maintenance require? #325222Maria FernandezMemberDry transformers don’t use oil but still require dust removal, thermal inspections, and thermal cycling checks. GlobeCore focuses on oil-filled units but offers tools to monitor oil-free systems as part of predictive maintenance plans.
September 9, 2025 at 12:43 pm in reply to: Why is transformer oil purification essential before energizing equipment? #324963Maria FernandezMemberContaminated oil leads to insulation breakdown. GlobeCore’s transformer oil purification restores BDV, reduces moisture below critical thresholds, and ensures safe operation of high-voltage equipment before it’s connected to the grid.
September 9, 2025 at 9:18 am in reply to: What is the process of transformer oil filtration with GlobeCore equipment? #324849Maria FernandezMemberGlobeCore transformer oil filtration includes: 1) preheating, 2) vacuum degassing, 3) moisture removal, 4) fine filtration, 5) BDV testing. This process restores dielectric properties and ensures safe transformer operation – all done efficiently in one automated cycle.
August 5, 2025 at 3:10 pm in reply to: What is Shell T32 turbine oil and how is it serviced? #323974Maria FernandezMemberShell T32 is a light-viscosity mineral turbine oil used in industrial gas and steam turbines. GlobeCore purification units filter and degas Shell T32, preserving its lubricating and thermal properties.
