The article considers a way to improve the efficiency of ship transformers. A temperature control system is used. In the process of changing the voltage in the ship's system, thermal losses of copper in the iron core and coil usually often occur. Thus, overloading will cause excessive heating and may affect the operation of the transformer. The calculation of the thermal parameters of the transformer is given. The mathematical model in Matlab is shown. The article proposes a functional diagram of the device. The control system monitors the temperature inside the transformer when operating under overload conditions. It is shown that the installation of the device will improve the performance o f the transformer and save its service life
