Servicing a transformer in summer isn’t just a routine task—it’s mainly about preventing failures when the equipment is under the most stress.
Our AKG experts are always on the toes to support you round the clock.
Here’s the logic behind it:
1. Higher temperatures = higher risk of overheating
In summer, ambient temperatures rise significantly. Transformers already generate heat during operation, so the extra external heat makes it harder for them to cool down. If cooling systems (like oil or fans) aren’t in good condition, the transformer can overheat and fail.
2. Increased load demand
Electricity usage often spikes in summer due to air conditioners, coolers, and refrigeration. This puts extra load on transformers. Servicing ensures they can handle this higher demand without breakdowns.
3. Transformer oil performance drops
The insulating oil inside transformers plays a key role in cooling and insulation. In high heat, Oil can degrade faster, Moisture contamination becomes more problematic, Insulation strength may reduce, Checking oil levels, quality, and filtration helps avoid insulation failure.
4. Dust and environmental effects
Summer often brings dust and dry conditions (especially in Delhi NCR).
Dust can block radiators and cooling fins, Reduce heat dissipation & Cleaning during servicing keeps cooling efficient.
5. Expansion and mechanical stress
Heat causes expansion of internal parts, seals, and connections. Loose contacts or worn gaskets can lead to Oil leakage, Hot spots & Electrical faults.
Servicing helps detect and fix these early.
6. Preventive maintenance before peak failure season
Most transformer failures happen during peak load + high temperature conditions. Servicing beforehand reduces unexpected outages when power is needed most.
