Dehydrating Breather

 
 

This is to prevent ingress of moisture in to the conservation system, where air circulation is controlled by liquid seal and special re-chargeable moisture absorbing material. The volume of charge in the breather is a function of the oil quantity in the transformer. The breathers are located at convenient height for inspection and recharging. Separate breathers are provided for the conservator (or partition) of the on-load tap changer. The charge is placed in a visible container so that the changes in the colour of the charge are easily visible.
