We Provide Comprehensive Transformer Oil Testing & Support to Monitor Insulation Health, Detect Faults Early, and Ensure Operational Reliability.
Protect Your Assets – Extend Transformer Life – Prevent Costly Failures
Transformer oil testing is a critical pillar of effective asset management, providing early insight into the health, reliability, and remaining life of high-value electrical equipment. At Yellotec, transformer oil analysis is not just a laboratory service — it is a strategic reliability solution designed to help asset owners prevent failures before they occur.
Through our ISO-accredited laboratory, Yellotec delivers precise, trustworthy results that support confident decision-making. With fast turnaround times and expert diagnostics, potential faults such as insulation degradation, contamination, or thermal stress can be identified early, allowing corrective action long before they escalate into costly, unplanned outages. This proactive approach enables cost-effective preventive maintenance, helping organisations optimise maintenance budgets while maximising equipment availability
Our Key Services Include:
