Oil in Transformer Conservator
Oil in Transformer Conservator
(OP)
Good Day!
In a Conservator type Transformer, the indication for oil level is in degrees Centigrade (why?). If the initial fill requirement is within 20 degrees, what level would that be inside the conservator tank, 3/4? 1/2?
Thanks in advance.

RE: Oil in Transformer Conservator
If the Oil Temp gauge is showing oil temp above 25°C, then the normal oil level should be above 25°C, and vice versa.

etc. for more info
The transformer was built to IEC or similar standards following the SI Units that includes Centigrade or Celsius scale.
Temperature will increase somewhat. Conservator is designed for a wide temperature range. The actual temperature values may be obtained from the manufacturer or in time, from meter readouts.

The fill level in the conservator should correspond to the temperature shown by the oil temperature indicator of the transformer.

When filling transf from dry, you should only pour in masured quantity stated on the name plate and that way you need not worry about under/over filling the unit.
RE: Oil in Transformer Conservator
I would never rely on the name plate value for the oil quantity for adjusting the right level. Thats usually a rough guess, because it's extremely difficult to calculate the required oil exactly. DanDel's explanation is correct.

1. IEEE Std 242-2001 Buff Book
Section 11.5.2.4 Conservation Tank
It does not address the conservation tank fill. The meter is leaving more scale for High than for Low around 25C. Therefore, to utilize the meter properly, it might be filled somewhere around 1/3 at 25C fill temperature. This is just by a popular mechanics of physics approach.

The inmportant thing is that the oil level at the gauge is close to the 25°C mark when the oil temperature is 25°C.
