Case Study
Cleaning Transformer Oil
Good results cleaning transformer oil with the Lubemaster OS600 at a Paper Mill.
Approximately 100 litres of waste Shell Diala M transformer oil was decanted into the Lubemaster. An initial sample of the oil was taken and testing showed the following results:
First Test Results
| Water % of Saturation | 70% |
| Dielectric Strength | 5kV |
| -Particle Count | |
| 15um | 254.2 |
| 25um | 64.2 |
| 50um | 7.7 |
| 100um | 9.0 |
Test Results Post-Cleaning
| Water % of Saturation | 20% – DOWN 48% |
| Dielectric Strength | 60kV – INCREASE OF 55kV |
| -Particle Count | |
| 15um | 121.7 |
| 25um | 25.7 |
| 50um | 1.9 |
| 100um | 0.3 |
Results
The Lubemaster filtered the oil for approximately 8 hours at 40degC with pump pressure of 60psi and vacuum -7. At this time a second oil sample was taken and tested. The tests showed the following results.
