Transformer oil analysis is a cost-effective preventive maintenance tool for your electrical power system. Both DYMAX and electrical transformer manufacturers recommend an annual dielectric fluid testing program.
The insulating fluid in a power transformer performs two major functions:
- Serves as electrical insulation to withstand the high voltages inside the transformer
- Acts as a heat transfer medium to carry out heat generated within the transformer windings
Dielectric fluid testing provides reference points that can show a historical trend in dielectric fluid condition. Quantitative analysis of impurities in the fluid can indicate the priority for preventive maintenance.
Transformer failure can be caused by gases and contaminants that dissolve in its dielectric fluid as the transformer ages. Sampling and analysis of the fluid form the cornerstone of transformer preventive maintenance.
Don't ignore fluid testing until a failure occurs, contact DYMAX now.
