Transformers typically work at their most efficient when they are kept at optimal temperature. Once it reaches a certain temperature, the transformer will begin to suffer heat damage. Over time, even a little too much heat can cause serious damage while a transformer that is very hot may burn out straight away. There are various ways to ensure that a transformer is able to perform at optimal temperature, with one of the most efficient and effective being liquid cooled distribution transformers.
Perhaps the most frequently used type of cooling for transformers is that of a basic air fan. The fan itself may burn out if it is used constantly or too frequently, but automatic fan switching systems can help ensure that the transformer remains cooler than it would without any form of cooling at all. These systems are not usually the most efficient, however, and many not prove effective for cooling high temperatures or where regular and ongoing cooling is required.
In a liquid cooled system, liquid is passed through tube or pipes and run around the system. The motion of the liquid can help keep it cool but if the temperature of the transformer is too high then it may be necessary to use more efficient liquids. Water is one liquid that can be used as a coolant but there are others that can be used instead.
Water may be one of the most obvious choices when considering what liquid to use as a coolant. It is freely available and it can be easily passed through thin pipes. However, the water itself needs to be kept cool and leaks may occur in these types of liquid cooled distribution transformers so maintenance is required. However, water can prove more efficient than air as a cooling substance.
Oil and other liquids are also used as the coolant solution in liquid cooled distribution transformers. Various components of the transformer are kept immersed in water and this helps to keep the whole transformer cool so that it can continue to operate efficiently and optimally. Oil is often considered to be one of the best choices especially in circumstances where the transformer needs a lot of cooling or needs to be cooled regularly and consistently.
