Transformer Oil level in conservator tank- practical

Feb 02,2015 brunei transformer tank building volume#0183;There should be some oil in the conservator tank for safe operation.As the transformer oil has a high expansion and compression value with temperature,with high temperature the oil volume increases and low temperature the oil volume decreases significantly.Design consideration for power transformer oil tank/ conservatorSpill Prevention Control and Countermeasure (SPCC) PlanV /V = brunei transformer tank building volume#247; = c is the secondary containment volume calculated in Step 1.d / e is the tank volume calculated in Step 2.c (ft 3) d or e (ft ) f % = x 100 = f g If percentage,g,is 100% or greater,the capacity of the secondary containment is sufficient to contain the shell capacity of the tank.If rain can collect in the dike or berm,continue to step 4.Spill Prevention Control and Countermeasure (SPCC) PlanV /V = brunei transformer tank building volume#247; = c is the secondary containment volume calculated in Step 1.d / e is the tank volume calculated in Step 2.c (ft 3) d or e (ft ) f % = x 100 = f g If percentage,g,is 100% or greater,the capacity of the secondary containment is sufficient to contain the shell capacity of the tank.If rain can collect in the dike or berm,continue to step 4.
