Common Faults and Causes in Routine Inspection of Distribution TransformersAs the terminal component of power transmission and distribution systems, distribution transformers play a critical role in supplying reliable electricity to end users. However, many users have limited knowledge of power equipment, and routine maintenance is often carried out without professional support. If any of the following conditions are observed during transformer operation, immediate action should be taken: Excess

Five Common Defects of H61 Distribution Transformers1.Lead Wire DefectsInspection Method: The three-phase DC resistance imbalance rate significantly exceeds 4%, or one phase is essentially open-circuited.Remedial Measures: The core should be lifted for inspection to locate the defective area. For poor contacts, re-polish and tighten the connection. Poorly welded joints should be re-welded. If the welding surface area is insufficient, it should be enlarged. If the lead wire cross-section is inade

With the rapid development of China's economy, the power industry has also gradually expanded in scale, increasing the requirements for both the installed capacity and the single-unit capacity of power transformers. This article provides a brief introduction to four aspects: transformer construction, transformer lightning protection, transformer faults, and transformer noise.A transformer is a commonly used electrical device capable of converting AC electrical energy. It can transform one form o
