A transformer repair service is needed when a fault occurs in a transformer. The faulty transformer can be repaired only when the occurred fault is repairable. There are only some faults that can be repaired in a transformer. There are basically two types of faults that can occur in a transformer and they are termed as External Faults and Internal Faults.
External faults in a transformer are the faults that occur outside a transformer. Various External Faults in a transformer are listed below:
- Lightning Strikes
- Short Circuit
- System Overload
Internal faults in a Transformers manufacturers India are the faults that occur inside a transformer and affect the electrical and magnetic property of the transformer. Various Internal Faults in a transformer are listed below:
- Insulation Deterioration
- Contamination of Oil
- Winding Failure
The external faults like lightning strikes, short circuits, and system overload generally burn up the transformer partially or completely. Therefore, the external faults are nearly impossible to be repaired. The internal faults can be prevented or avoided by the maintenance of the transformer on the regular basis. In any case, if a fault occurs then it can be repaired easily but it will take time. The transformer faults take a long time to be repaired.
In an insulation deterioration defect, the insulation on the transformer windings starts to fail. This can shorten the transformer circuit and damage it completely. When the transformer oil, which acts as a coolant and provides insulation, is contaminated with outside particles then it can lose its characteristics that are required. A very high current in the transformer winding can create the problem of overheating in the transformer. Thus, these faults can create a big problem but they can be avoided or prevented by appropriate maintenance and testing on a preferred interval of time.
Generally, repairing a transformer is a better choice than replacing the transformer which, as a result, reduces the cost of investment in a plant and also avoids the cost of manufacturing a new transformer. The companies that manufacture the transformers, also provide the transformer repairing services. But there are also other companies that only provide transformer repairing services. For this purpose, these companies have special equipment or machines for each kind of defect or fault occurred in a transformer. The faults in a transformer can be repaired either on-site or in the workshops. The on-site repairing services save the transportation cost as well as time.
