Basic Transformer Breather Questionnaire Summary
1. The transformer breather oil content is the prime multiplier for sizing breathers for the amount of desiccant required to look after it for a given period of time. The amount of desiccant used is directly proportional to the time the transformer breather will last before reactivation or replacement is required.

2. The transformer rating (KVA) will be directly linked to the size of the transformer and the amount of oil held within the transformer. This in turn can be linked to the size of breather required.

3. The minimum period between desiccant changes should be tied in with other routine maintenance schedules. This may well involve fitting a breather which is much larger than would normally be fitted.

4. Vent pipe connection information is important to establish because of the additional costs involved if they do not conform to the existing standard units.

5. If an existing unit is already fitted it is important to establish the type and the mounting configuration. It is also important to establish the support work required (for larger breathers).

6. For small transformer breathers (below 4000 litres) it may not be viable to fit the cartridge type breathers because of the addition]. cost. In cases like this we would probably advise the use the disposable type (RI, R2 & R3 ). Although they are described as disposable it is possible to refill them with new or reactivated desiccant.
