Power transformers don’t operate in a static state - they continuously adapt through one of their most critical components: the OLTC (On-Load Tap Changer).
But while OLTCs are essential for voltage regulation and grid stability, they are also among the most failure-prone parts of a transformer. Mechanical wear, contact degradation, electrical arcing, and timing deviations often develop silently, long before a traditional alarm is triggered.
That’s where PrediTransf from ENGING brings a new layer of intelligence.
By combining Electrical Signature Analysis (ESA) with advanced diagnostics and AI-driven monitoring, PrediTransf provides deep visibility into both transformer and OLTC behaviour — detecting early signs of abnormal operation that conventional methods often miss.
This means operators can move from reactive maintenance to informed, condition-based decisions with greater confidence and precision.
⚡ Early detection of OLTC mechanical and electrical anomalies
🔍 Continuous transformer health assessment
🧠 AI-driven interpretation of complex electrical signals
⏱ Reduced risk of unexpected failures and outages
📈 Improved reliability of critical grid assets
Because transformer reliability is not just about the tank - it’s about every operation happening inside it.
