<p>An automatic trip device, a network system using it and control method thereof is related to providing the prediction of a potential electrical accident, in which measuring data including a temperature and a current from each of temperature and current sensors (11,12) is received, the measuring data is stored in a data memory (13), the measuring data and a setting data are compared with each another and analyzed, an indicating portion (16) display the life spans of an appliance equipment and mechanism and a power litte section accommodating the interrupter, a temperature resistance coefficient based on the temperature stored is calculated, the temperature resistance coefficient is compared with one previously stored for the warning, the power line is interrupted and a warning portion (17) is controlled to generate a warning signal if the calculated temperature resistance coefficient is higher than the warning temperature resistance one, thereby interrupting an accidental high current, rapidly, to protect persons and installments in itself, preventing the spreading of a general failure of power supply and minimizing an amount of damages.</p> |
