Decline in Electrical Performance<\/em><\/h3>\n<p>As the insulation ages, its insulation resistance decreases. This means that the leakage current inside the transformer increases, which may lead to the intensification of partial discharge phenomena. The energy generated by partial discharge will further accelerate the insulation aging, forming a vicious cycle. Moreover, the dielectric constant and dielectric loss tangent of the aged insulation material may change, affecting the electric field distribution of the transformer, reducing its withstand voltage capacity, increasing the risk of insulation breakdown, and thus possibly triggering short-circuit faults, which will seriously affect the power supply.<\/p>\n<h3><em>2. Deterioration in Heat Dissipation Performance<\/em><\/h3>\n<p>Insulation aging may cause problems such as cracks and spalling in the insulation layer. These problems will affect the heat conduction channels inside the transformer. Under normal circumstances, the insulation material helps with the uniform distribution and transfer of heat. However, the aged insulation cannot effectively transfer the heat to the cooling medium. Heat accumulates inside the transformer, leading to a rise in temperature. And the high temperature will further accelerate the aging speed of the insulation material. Meanwhile, it may also increase the resistance of the windings, generating more heat and reducing the operating efficiency of the transformer.<\/p>\n<p><a title=\"Transformateur, de Gros Transformateurs de Fournitures et de Fabricants,Sp\u00e9cialis\u00e9e dans les Transformateurs de 49 ans\" href=\"https:\/\/www.lstransformer.com\/fr\/Transformers\/\" target=\"_blank\" rel=\"noopener\"><img fetchpriority=\"high\" decoding=\"async\" class=\"aligncenter\" title=\"40\" src=\"https:\/\/manage.lstransformer.com\/upload\/news\/1741942542173721.jpg\" alt=\"undefined\" width=\"440\" height=\"422\" border=\"0\" vspace=\"0\" \/><\/a><\/p>\n<p>&nbsp;<\/p>\n<h3><em>3. Reduction in Mechanical Strength<\/em><\/h3>\n<p>The aged insulation material will become fragile. During the operation of the transformer, due to the action of mechanical stresses such as electromagnetic forces, the insulation may get damaged. Especially under circumstances such as short-circuit impacts, the insulation can no longer provide sufficient mechanical support and protection for the internal structures such as the windings, which may lead to the deformation and displacement of the windings, further affecting the normal operation of the transformer and even causing permanent damage to the transformer.<\/p>\n<p><a title=\"Transformateur, de Gros Transformateurs de Fournitures et de Fabricants,Sp\u00e9cialis\u00e9e dans les Transformateurs de 49 ans\" href=\"https:\/\/www.lstransformer.com\/fr\/Transformers\/\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" class=\"aligncenter\" title=\"41\" src=\"https:\/\/manage.lstransformer.com\/upload\/news\/1741942560845683.jpg\" alt=\"undefined\" width=\"440\" height=\"422\" border=\"0\" vspace=\"0\" \/><\/a><\/p>\n<h2><b><span style=\"font-family: Arial;\">En R\u00e9sum\u00e9<\/span><\/b><b><\/b><\/h2>\n<p>The impacts of insulation aging on transformers are multifaceted, with negative effects that cannot be ignored in terms of electrical performance, heat dissipation, and mechanical strength.
