Abstract

The present invention relates to a distribution transformer with a display function and a display device of the same, wherein the distribution transformer comprises a temperature sensor for sensing and outputting a temperature inside the transformer; a current sensor for sensing a current of the transformer; a voltage sensor for sensing a voltage of the transformer; a display for displaying information; and a control module for displaying temperature, current and voltage of the transformer on the display using electric signals received from the temperature, current and voltage sensors, so the overall condition of the transformer such as the running state, load, temperature, oil level, data transmission/receiving, acid value of insulating oil can easily be displayed, or provided in a manner for a user to visually check. In so doing, a low-cost implementation is facilitated, and a transformer diagnosis can be made conveniently during the day as well as at night.
