the transformers suitable for toughe
This covering makes the transformers su find itable for tougher environmental conditions. Due to the limitation in the cooling aspect, the maximum voltage in dry type transformers are limited up to 35kV. Dry Type Transformers vs. Oil Type Transformers · Maintenance Oil typeelectrical transformers require greater maintenance processes as compared to dry type transforme house rs. Th v e mineral oil present has to be sampled and tested for contaminants annually as part of preventive maintenance procedures. Apart from this, oil filtrat v ion should also be done at least once a year. On the other hand, dry type transf business ormers are resistant to chemical contaminants, thus reducing the need for carrying out maintenance procedures. · Operating Costs Oil type transformers have higher energy efficiency that helps in increasing their lifespan, thus resulting in limited operational costs. Compared to oil type transformers, dry type trans
