TJ|H2b has developed 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 oil diagnostics and consultation services to give as complete an analysis as possible. For more information, select a diagnostic.
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.
Code 1: All parameters within acceptable limits.
Code 2: Onset of fault activity or oil degradation is evident.
Code 3: Substantial development of fault and/or deteriorating oil quality.
Code 4: Serious fault activity and/or very poor oil quality. Further investigative action is required.
Code 4*: Urgent action required. Retest immediately. Subject to confirmation via repeat sample, an internal inspection may be required, proceed immediately and with caution.
Along with these oil diagnostic evaluations and condition codes, multiple other factors must be taken into consideration such as:
Service History / Maintenance History / Age / Criticality
