What Causes Overheating of Transformer Core?<\/b><\/h1>\n

The overheating of a transformer core can be attributed to several factors:<\/p>\n

(1) Overload: <\/span><\/strong>When a transformer operates under excessive load, the current passing through the core increases, generating additional Joule heating. This can result in an elevated temperature of the core, surpassing the design temperature.<\/p>\n

(2) Iron Loss:<\/span> <\/strong>The iron loss of the core is related to the magnetic flux density and frequency during transformer operation. If the operating point deviates from the design point, causing an increase in iron loss, it can lead to overheating of the core.<\/p>\n

(3) Harmonics:<\/span> <\/strong>During transformer operation, harmonics in the system can induce overheating of the core. Harmonics cause additional losses in the core, contributing to an increase in core temperature.<\/p>\n

(4) Poor Connections:<\/span><\/strong> If there are issues with the connections or localized insulation failure in the core, it may result in local overheating when current passes through these points, subsequently causing overheating of the core.<\/p>\n

These factors, when combined, can lead to the overheating of the transformer core. Therefore, it is essential to be vigilant about these potential issues during both the design and operational phases to ensure the stable operation and safety of the transformer.<\/p>\n
