| titleOfInvention | Method and apparatus for measuring the temperature of the hot spot in an electrical device containing oil |
| abstract | The present invention relates to a method for measuring the actual temperature of the hot spot in an electrical device containing oil, such as a transformer. The electrical device is operated under predetermined and variable operating conditions. This method involves the use of one or more chemical compounds or tracers that are present and soluble in the oil. Each tracer can be converted at a given temperature to form a residue such as a soluble gas. Due to the presence of residues in the oil, the operator can determine at which predetermined operating conditions the hot spot is reached and from there can derive the hot spot for a given condition. Different compounds used include diazo compounds, carbonyl metals, dyes, pigments, liquid crystals, or albumin. This method can also be used to check the quality of commercially available equipment and estimate its lifetime. [Selection figure] None |
