Transformers are critical assets in

power networks. Maximizing their use

requires increasing power throughput

and reducing aging. Digital monitoring

of key parameters helps operators

protect their transformer investments.

CoreTec™ 4 is a modular monitoring

platform that collects, aggregates and

analyzes critical data to assure a

transformer continuously delivers

optimal performance.

Optimize your transformer with live data CoreTec™ 4 enables real-time management of a transformer by monitoring key health parameters such as oil temperature, ambient temperature and load. Using live data, CoreTec™ 4 models algorithms based on IEC and IEEE standards to warn the operator of any sudden changes in a transformer’s condition.

Detect faultsAvoid unplanned outages by continuously measuring oil temperature, load and gas formation. Variations in these health thresholds are flagged by CoreTec™ 4 in real time and can trigger advanced investigations when needed, not when scheduled.

Reduce insulation agingOil and Paper aging is linked to temperature, moisture and oxygen variations. CoreTec™ 4 tracks these parameters and activates the coolers sooner than conventional systems to delay insulation aging.

Increase load capacityMake informed decisions on overloading your trans-former. CoreTec™ 4 tracks current environmental conditions and uses international standards to provide an overview of the short-term overload capacity. This allows the operator to consider transformer aging versus increased throughput and revenues.

Delay replacement of a sick transformerCoreTec™ 4 can help operators with a sick transformer by enabling them to run it below recommended critical limits for temperature and gas generation. Ultimately, this helps to better plan for maintenance or delay replacement.

Integrate with ABB’s digital offeringThe CoreTec™ 4 platform is modular and expandable to suit your present and future requirements. Choose from a variety of transformer sensors like ABB’s CoreSense™ for DGA sensing or ABB’s eDevices to feed the CoreTec™ 4 with additional actionable data. CoreTec™ 4 can also integrate within ABB Ability™ Ellipse® asset performance management software.
