How much oil is required for specific kVA transformers?

The amount of oil required for specific kVA transformers varies based on the transformer’s design and cooling requirements. Generally, a rule of thumb is approximately 1 liter of oil per kVA for smaller transformers. For larger units, this can range from 0.5 to 1.5 liters per kVA, depending on factors such as insulation type and cooling method. Always consult the manufacturer’s specifications for precise oil volume requirements for each transformer model.
