1. Real Time Notification
The board authorities were swiftly notified by the BOLA device, which delivered real-time alerts indicating deviations in both oil temperature and overload, enabling them to promptly address potential issues and maintain optimal operational conditions.
2. Temperature Increased
In the comprehensive case study, it was determined that the transformer's operational parameters were closely monitored, revealing a crucial finding: the maximum oil temperature reached 72 degrees Celsius.
Root Cause Analysis
View
1. Transformer Overloading
Throughout a specific month, the transformer consistently operated under a load exceeding 120% of its rated capacity, signaling a sustained period of elevated demand.
2. Electricity Theft
Situated in a distant location, the transformer encountered frequent instances of electricity theft, identified through the BOLA IoT device.

1. Data-Driven Recommendations
The KRYFS team proposes a strategic approach — maintain the load consistently below 80% of the maximum rated load to prevent transformer overloading.
2. Performance Optimization
Avoiding overloading not only preserves operational efficiency but also extends the transformer's lifespan, ensuring sustained reliability and minimizing potential issues.
Result
View
1. Transformative Efficiency
Based on KRYFS recommendations, the utility board maintained loading below 80% and as a result, maximum oil temperature was monitored below 50 degrees Celsius.
2. Cost Saving
Premature failure due to excessive heating was avoided. The life of the transformer increased by about 5 years and saves repair and maintenance cost approximately of Rs 60K.
