An online transformer oil filtration system purifies transformer oil while the equipment is in operation, removing moisture, gases, and particles. This continuous process ensures optimal performance, improves the lifespan of transformers, and reduces maintenance costs. Wrindu, a leading supplier from China, offers both OEM and custom solutions for businesses worldwide, ensuring reliability and high-quality service.
What Does an Online Transformer Oil Filtration System Do?
An online transformer oil filtration system works by removing free water, dissolved gases, and solid particles from transformer oil without de-energizing the transformer. This process maintains the oil’s dielectric strength, preventing breakdowns and enhancing transformer efficiency. It ensures that oil quality is kept within specific standards, such as ≤5 ppm of water, ≤0.1% gas content, and NAS 5 cleanliness, ultimately extending the transformer’s operational lifespan.
Wrindu’s systems, built with advanced filtration technology, are designed for continuous operation in power plants, substations, and industrial grids. Using double-stage vacuum dehydration, high-precision filtration, and real-time monitoring, these systems operate efficiently without interrupting power delivery. Wrindu’s custom solutions cater to diverse industries, providing reliable and sustainable solutions to customers worldwide.
How Does an Online Transformer Oil Filtration System Work?
The process begins when oil is drawn from the transformer’s lower section. It is then filtered through a series of pre-filters, passed through a vacuum dehydration chamber to remove water, and a degassing chamber to eliminate gases. The clean oil is then returned to the top of the transformer. Continuous monitoring of parameters like moisture, gas, and particulate levels ensures the system runs at peak efficiency.
Wrindu’s systems are equipped with multi-stage processes. Oil is first heated to reduce viscosity, followed by coalescing separation to remove water, vacuum pumps to extract gases, and lamella filters to capture particles. Automation through a PLC system ensures minimal operator intervention, while interlock safety features prevent any system malfunction. Wrindu also offers OEM solutions customized to transformer volumes and specific operational requirements, including mobile and stationary setups for power grids.
What Are the Benefits of Online Transformer Oil Filtration?
The key benefits of online transformer oil filtration include extended transformer lifespan, reduced maintenance costs, and improved dielectric strength. By continuously removing contaminants, the system prevents insulation degradation, reducing the risk of transformer faults and outages. With online filtration, the system operates without the need for downtime, ensuring minimal disruption to operations.
Wrindu’s filtration solutions offer significant advantages, including energy-efficient heaters and backflushable filters. These features contribute to a reduced operational cost and a higher return on investment (ROI). Additionally, Wrindu’s systems support global certifications like CE and ISO9001, ensuring quality and safety in both industrial and power generation environments.
