Transformer Monitoring

Main Tank

TOTUS monitors and correlates all key components in the main tank including DGA, Partial Discharge, High Energy Events & Through Fault Current.

Key Challenges

Failures in power transformer windings account for more than 40% of transformer failures.

The key challenge for asset managers is finding power transformer faults in their infancy, allowing more time for decisions to be made resulting in less expensive maintenance. Manual sampling of dissolved gas analysis (DGA) can result in delayed discovery of faults, and often faults have progressed causing dissolved gas analysis changes in transformer oil.

TOTUS monitors all key areas (not only DGA analysis) within the main tank of the power transformer and correlates data for asset managers for early fault diagnoses and detection. Featuring embedded advanced alarm management, TOTUS drives efficient maintenance scheduling for asset managers, with alerts only triggered when there is an issue with the power transformer.

Benefits of DGA monitoring with TOTUS

DGA online monitoring enables proper condition based monitoring to drive efficiency

Accuracy, reliability, repeatability

TOTUS is monitoring your power transformer 24/7, 365 days, enabling early warning and diagnoses of faults, providing reliable trending of data which can be trusted to make the correct decisions.

Key benefits include:

  • Closed loop system - Enabling repeatably of measurements, maximising accuracy removing margins of error
  • Automated measurements – Data can be communicated directly into the SCADA system, or asset management platform for asset managers
  • Web based analytics – Automatic reporting and trending to give early indications of fault to plan maintenance

DGA Monitoring with TOTUS

Online monitoring of DGA enables proper condition-based monitoring to drive efficiency.

TOTUS continually monitors power transformers, providing early warning and diagnoses of faults, with reliable trending of data to enable Asset Managers to take effective decisions.

Key benefits include:

  • Closed loop system - Enabling repeatably of measurements, maximizing accuracy removing margins of error.
  • Automated measurements – Data can be communicated directly into the SCADA system or asset management platform for Asset Managers.
  • Web based analytics – Automatic reporting and trending for early indications of faults, to assist with maintenance planning.

DGA Matrix

Dissolved Gas Analysis (DGA) is a technique widely used to diagnose insulation oil to prevent power transformer faults. Duval Triangle and Duval Pentagon are two of most used methods for Dissolved Gas Analysis in transformers, but there are other techniques suggested by IEEE, IEC and ETRA. Which one is the correct one?

TOTUS is the only system that can detect arcing in a transformer

The Challenge

DGA is typically used to detect discharge of high energy (D2), with Acetylene being the primary marker. The challenge for asset managers is little visibility on when the arc occurred and in which phase and winding, as well as no tracking on the number of arcing events.

TOTUS Value

Whereas other monitors can provide basic information identifying acetylene in the transformer, TOTUS delves deeper into arcing activities, identifying the phase and winding, as well as visibility on the number of arcing events. They key benefit is the ability to correlate the data and generate a deeper understanding of changes in the transformer.

TOTUS is the only solution to embed an online Health Index calculation combining DGA, PD & Bushing condition

Challenge

Asset managers are facing increasing time constraints coupled with reductions in man power all while facing critical decisions every day on transformer health. Often fast decision making is required and access to accurate and real time information is critical.

    TOTUS Value

    TOTUS provides quick embedded and intuitive assessment of transformer health, with no need to send data to a server or run complex analytics. Our condition group correlation correlates PD, Bushings & DGA via an easy to configure web portal, with no additional software required. TOTUS Enables full fleet condition view for asset managers.

      Withstanding capabilities of a transformer

      Challenge

      The largest cause of transformer failures is due to external events. In particular through faults are responsible for 20%+ of failures. Visibility of the impact of through faults to the transformer is challenging for asset managers.

      TOTUS Value

      Understanding which transformer is more effected than others plus visibility of the integrity of paper insulation can help assess the mechanical strength of the transformer and the risk for mechanical damages. We monitor the stress caused by through faults and the cellulose ageing due to combined action of temperatures, moisture and oxygen.
