Transformer condition monitoring – Sensors vs Analytics: A chicken and egg situation revisited
Dr Bhaba P. Das
Abstract
Transformer online condition monitoring (OCM) is no longer optional for asset-intensive end users; it is essential for reliability, safety, and cost-effective operation. However, the interplay between sensor deployment and data analytics remains a stumbling block. Drawing from field deployments across the Asia-Pacific region, this article explores how a co-evolutionary approach to sensors and analytics enables advanced asset management. I examine why neither sensors nor analytics alone are sufficient and demonstrate how OCM becomes valuable only when aligned with asset health frameworks, investment decisions, and risk-informed maintenance.
