Water cooling applications on power transformers with open loop system with the oil circulation being closed loop. To prevent contamination of the oil with water the coolers are usually designed with either double finned or having and intermediate closed loop low pressure water circulation. Leak detection is usually provided. These configurations are presented in the diagrams below.

Health Concepts

Just like a Human, power transformer health can also be analysed by testing the levels of hydrocarbons and gases in the oil.
