PURPOSE: A system for the accident prevention and accident cause analysis of transformer is provided to easily prevent and analyze the accident of a transformer by managing the size and duration of an inputted voltage, a current and a duration which exceed a rated capacity, and temperature.;CONSTITUTION: A voltage signal pre-process part(20) produces the effective value and instantaneous peak value of a voltage in a transformer and transmits them to an operation part(50). A current sensor signal pre-process part(30) receives a signal which is detected from a current sensor, calculates the effective value of a current transformer, and transmits the effective value to an calculation part. A temperature sensor signal pr-process part(40) receives the signal detected from the temperature sensor, calculates the temperature of the transformer, and transmits the temperature value to the operation part. The operation part receives signals from the voltage signal pre-process part, the current sensor signal pre-process part, and the temperature sensor signal pre-process part, calculates the mean value of the transformer voltage, the mean value of the current, the mean value of the temperature, the maximum instantaneous peak value of the voltage, and the maximum value of the current during a preset first constant time, and stores them.;COPYRIGHT KIPO 2012
