Transformers are vital assets in power distribution systems. PRISM, our innovative IoT-based solution, offers real-time monitoring and diagnosis for Power/Distribution Transformers.
According to the CIGRE Transformer Reliability Survey, approximately one out of every 200 transformers fails each year worldwide. In India, the rate is significantly higher, with approximately 20% of distribution transformers failing annually, compared to 2 – 3% in developed countries.
Common reasons for transformer malfunctions include insulation failure, moisture ingress, oil decay, line surges, fire or explosion, overloading, and improper setup.
The consequences of an unexpected transformer failure can be severe, yet many of these failures are entirely preventable. PRISM addresses these challenges by providing proactive and cost-effective monitoring, enabling timely maintenance interventions. By ensuring optimal transformer performance, PRISM helps improve safety, reduce the risk of failures, and mitigate costly repairs through timely action.
