Case Study 3
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
