## How do you check the oil on a transformer?

Breakdown voltage testing procedure

1. The transformer oil is filled in the vessel of the testing device.
2. A test voltage is applied to the electrodes and is continuously increased up to the breakdown voltage with a constant, standard-compliant slew rate of e.g. 2 kV/s.

## What is the density of transformer oil in liters?

Density of Transformer Oil at 29.5oC is 0.89g/cm3.The exact density of transformer oil depends upon the manufacturer but, expressed in SI units, is typically a little less than 900 kg/m3 at 20oC.

## How is the breakdown voltage of a transformer oil measured?

In the vessel, two standard-compliant test electrodes with a typical clearance of 2.5 mm are surrounded by the insulating oil. During the test, a test voltage is applied to the electrodes. The test voltage is continuously increased up to the breakdown voltage with a constant slew rate of e.g. 2 kV/s.

## How to calculate the density of an ounce of oil?

Thus, 2.5 oz. would be 2.5 x 30 = 75 mL. If the weight of the oil was measured in ounces, convert this to grams by multiplying by 28. Thus, 2.0 ounces would be 2.0 x 28 = 56 grams. Calculate density by dividing the mass in grams by the volume in milliliters. Using the values from step 5, 56 grams / 75 mL = 0.75 g/mL.

## How to choose the best oil for a transformer?

It is very important to know the viscosity of your chosen oil at low temperature extremes and at high temperature extremes. Choose the oil by density and viscosity that will give your transformer the best possible range of operation regardless of high or low temperature extremes.
