TRANSFORMERS

Power transformers play a critical role in maintaining operational continuity and electrical reliability. Routine transformer oil analysis helps detect developing faults, insulation degradation, contamination and fluid aging before they lead to costly repairs or equipment failure. POLARIS Laboratories® provides comprehensive testing and expert interpretation to help asset managers extend transformer life, improve reliability and make more informed maintenance decisions.
