India, Bangalore: After a transformer blast at Koramangala a few weeks ago, faults with electrical installations have been revealed. Bangalore Electricity Supply Company (Bescom) has found that the percentage of distribution transformers failure (includes step-up and step-down transformers) has become the highest in the last five years.
Findings by Bescom have revealed that failure percentage of transformers was 8.27 %, which is the highest in the last five years.
Transformer failure has always been common in rural areas but now, even well off localities in Bangalore witnessed failure of distribution transformers at an alarming rate. Apparently, the Bescom managing director has expressed his displeasure over the issue.
According to Bangalore Mirror, of the existing 44,377 distribution transformers across Bangalore, 221 transformers are down.
Yelahanka region witnessed the highest failure with 150 transformers, followed by Jayanagar with 29 defective transformers, Koramangala with 18, and HSR Layout with 16, reports Bangalore Mirror.
Unauthorised irrigation pumpsets (IP sets) are normally the main reason for transformer failure in rural areas but overloading and bad maintenance are believed to be the major cause for failures in the city.
An enginner explained: “It could be increased load on the transformer over the years. We may have installed a lesser capacity transformer years ago and with the passage of time, the load would have increased substantially. Hence the MD has directed all senior executive engineers (SEEs) and executive engineers (EEs) to take up enhancement works wherever the overload is not caused by IP sets.”
According to Badarinath S, an energy consultant, if one transformer fails, it could lead to failure on all connected electrical lines. He explained that only systematic and timely maintenance of transformers would help safeguard them.
