Transformers are very important electrical equipment in power systems, but they may fail due to various reasons during use. At this time, timely troubleshooting is required to ensure the normal operation of the transformer.

Common transformer faults include winding short circuit, ground fault, insulation aging, etc. In order to troubleshoot these faults, the following steps are required:

1. Check the electrical wiring of the transformer to ensure that each line is connected correctly and the insulation is good.

2. Check the winding of the transformer to confirm whether there are problems such as short circuit, open circuit or insulation aging.

3. Check the cooling system of the transformer to confirm whether there are problems such as blockage and leakage.

4. Check the protection system of the transformer to ensure that all protection devices work normally.
