  • TJ/H2b TASA   | TapChanger Activity Signature Analysis
    TJ/H2b TASA | TapChanger Activity Signature Analysis

    The first applications of DGA to evaluate load tap changer condition were based on experiences with transformers.Threshold limits were developed for the gasses produced by overheating both individually and in combination. Many factors such as design, operations, ventilation, and on-line filtration affect gas levels. Consequently, this gas threshold approach offered limited success but proved the potential usefulness of fluid testing for LTC condition assessment.

  • TJ/H2b BOA   | Breaker Oil Analysis
    TJ/H2b BOA | Breaker Oil Analysis

    BOA® has been extensively field-tested and has proven to enhance equipment reliability. No false negatives have occurred with the BOA® service, which means that no tanks that have been assessed have been found to be in a poorer condition than indicated. Conversely, false positives are not a concern because BOA® has been designed to address the residual contamination of tanks from prior maintenance activities. This can occur when the used oil is replaced in the unit after repairs are made or when the unit is insufficiently cleaned and flushed after maintenance.
