A: an oil-immersed power transformer is a type of transformer that uses oil as coolant and an insulator simultaneously. The oil circulates around the oil immersed transformers bringing the required advantage of cooling and insulation for the conductors.
A: Oil-immersed power transformers utilize oil and paper separators to ensure effective energy flow. The circulating oil dissipates the heat produced due to the flow of electrical current. It helps controll the temperature of the transformer during the operation which improves its efficiency.
A: The major benefits of these transformers include exceptional thermal management, superior insulation, long service life, and robustness. Compared to dry-type transformers, oil-filled transformers have a significantly higher load bearing capacity. They can also operate over a much broader temperature range. Moreover, their configuration makes them suitable for a range of energy projects, especially for use in power transmission and distribution.
A: Oil quality is directly related with an oil immersed power transformer as it affects its performance qualitatively. It negatively affects the performance of the transformer if the oil is not contaminated. Thus, maintenance is required to test the oil regularly in order to enable detection of faults prior to failure.
A: The role of insulation materials in the design power transformers, especially immersed in oil, are very vital. Gaps between conductors must have proper di-electric strength, preventing discharges and ensuring protection to the transformer.
A: One of the most effective methods for determining transformer faults with connection to immersion in oil would be dissolved gas analysis. Thermodynamic processes make it possible to analyze certain gases in hybrid fluids providing the possibility to find precursors: overheating, arcing, and insulation breakdown.
A: Phase drying is a technique of removing moisture in oil-immersed power transformers. Moisture in the oil and insulation paper degrades the performance and longevity of the transformer. Low amounts of moisture during phase drying reduce the chances of transformer faults, and improves the reliability of the transformer in the long term.
A: Oil-immersed power transformers are predominantly used for high-voltage applications, as they are not designed for low-voltage use. Due to their rugged construction and superior cooling features, they are well-suited for multi-million kVA energy projects.
A: For oil-filled transformers, the primary concern is the possible leakage of oil which may not only contaminate the soil but groundwater as well. As a result, fully enclosed designs of transformers are executed and some even use negative pressure systems to mitigate ecological damage. For these types of systems, preventative maintenance is needed to monitor the oil and the integrity of the system.
