TJ|H2b has developed four diagnostic evaluations for differing types of high voltage electrical equipment: Transformer Condition Assessment (TCA®) for oil insulated transformers of any size, Tap Changer Activity Signature Analysis (TASA®) for on- load Tap Changers, Breaker Oil Analysis (BOA®) for oil-filled circuit breakers, and Breaker Gas Analysis (BGA®) for gas-filled circuit breakers. TJ|H2b provides equipment specific diagnostic evaluations and consultation services to give as complete an analysis as possible. For more information, select a diagnostic.

Transformer Condition Assessment (TCA®)

A transformer diagnostic that provides information on the overall condition of a transformer including specific faults, oil quality issues and the estimated Degree of Polymerization of the cellulose insulation.

Tap Changer Activity Signature Analysis (TASA®)

Our well-proven diagnostic for on-load tap changers locates specific faults within the oil-immersed components, which in turn aids asset managers in planning maintenance and successfully avoiding failure.

Breaker Oil
Analysis (BOA®)

Our diagnostic for oil-filled circuit breakers helps minimize maintenance by identifying only those units in need of attention, while at the same time identifying units on the verge of failure.

Breaker Gas
Analysis (BGA®)

Like oil in oil-filled equipment, SF6 can be sampled and tested to gain an assessment of equipment condition and fluid quality. TJ|H2b has developed a unique and simple sampling method that can ensure a sample of high integrity is taken.

The above diagnostic packages assign a condition code (1, 2, 3, 4 or 4*) to the equipment, in addition to detailed interpretation of the results. This information aids asset managers in planning and prioritizing maintenance, thus providing real savings on unnecessary maintenance and costly outages and failures.
