Transformer Oil – Cleaning.
Good results cleaning transformer oil with the Lubemaster OS600
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:
Water % of Saturation | 68% |
Dielectric Strength | 5kV |
Particle Count | |
15um | 254.2 |
25um | 64.2 |
50um | 7.7 |
100um | 9.0 |
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.
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 |
