What's in Your Oil?™

Transformer Condition Assessment (TCA®) is 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®) is our well-proven diagnostic for on-load tap changers.  TASA® 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®) is our diagnostic for oil-filled circuit breakers.  The goal is to minimize maintenance by identifying only those units in need of maintenance while at the same time identifying units on the verge of failure.

Breaker Gas Analysis (BGA®) for SF6 Filled Equipment:  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. 

Microscopy and Forensic Analyses: TJH2b Analytical Services uncovers particles at the microscopic level in your oil and identifies their makeup and origin in order to help you better understand what’s going on inside your electrical power equipment, root cause failure analysis and in depth investigations.
