Power Transformer Research - How it is Conducted

Transformer oil and cellulose insulation have an inter-dependent relationship. To estimate the remaining safe life of a transformer, CPTM studies both as well as various loads and stresses. Based on this research, CPTM aims to develop systems for both monitoring and diagnostic purposes. To achieve this goal, CPTM conducts research in three major steps. Step 1: Physical Model
The physical models of cellulose and oil systems are studying. This involves many measurements on the specially-modified transformer in CPTM's research facility.

Step 2: Mathematical Model
The information obtained from these physical models is embodied in algorithms and mathematical models. These are then further developed and tested with the test transformer, allowing experimental validation of theoretical results.

Step 3: Field Experiment
Studies are performed using real transformers, some at Wilson Transformer Company's factory and others at operational field locations.

Some monitoring is performed using transformers owned by the project's sponsors. These transformers are monitored continuously and the Centre has access to all the online and offline data for its research work. The results and solutions we obtain are implemented in running transformers. Some of our findings belong to our collaboration partners, while others can be published.
