rpe, particularly for high voltage installations. Sometimes transformers in power stations are air-cooled.In this method a fan forces cool air up from the bottom of thetransformer, past the coils and core, so as to carry off theexcess heat from the top of the transformer. Such trans-formers are not… … Fig. 259. Water-cooled transformerin its case. 380 ELECTRICITY AND MAGNETISM If the insulation breaks down and an arc is formed, it is fannedinto flame by the air currents instead of being quenched bythe oil. Unless great pains be taken to filter the air, the trans-former gets dirty, which injures…
