![]() ![]() The radiator is used to increase the transformer’s cooling efficiency.Thermal relay is used as an indicator for the temperature of the winding.Pressure relief device decreases the pressure within the transformer to avoid an explosion of the transformer.If the temperature of the oil increases to a certain level then the transformer will be disconnected from the service. The temperature detector monitors the temperature of the oil.The oil indicator indicates the level of the oil within the conservatory unit. ![]() It changes its color from blue color to pink color it is not capable to absorb moisture in the oil. Breather Unit includes silica gel that absorbs moisture in the oil.Because it indicates errors like loss of oil once it goes low, improper flow of oil between the tank & transformer. Buchholz relay is used when a conservator tank is used.The oil within the tank can be easily contacted & enlarge throughout loading so that the temperature of the oil can be increased & decrease. It is connected to the main tank with the help of a metallic tube. A conservator is arranged above the oil tank at the outside of the transformer frame.The oil tank is used to soak the windings by placing it in.The main parts of this transformer mainly include Oil Tank, Conservator, Buchholz Relay, Breather Unit, Oil Indicator, Temperature Detector, Pressure Relief Device, Thermal Relay, Radiator, and Bushing. The designing of a distribution transformer can be done similarly to small size transformers. ![]()
