Abstract: PURPOSE: A lightning arrester degradation diagnosis system and a method thereof are provided to process measured results using software by arranging a main system and a sub system on different places. CONSTITUTION: A main system(100) measures a leakage current flowing through a lightning arrester or operating voltage received by the lightning arrester using a measurement part(101). A sub system(110) measures the leakage current flowing through the lightning arrester or the operating voltage using a measurement part(111) by being arranged separate from the main system. The main system and the sub system include wireless communications modules(104,114). The sub system transmits a lightning arrester degradation diagnosis synchronous signal to the main system in order to measure the leakage current or the operating voltage at the same measurement time point as the main system.

The capacitive leakage current of the arrester is calculated based on the capacitance(S340). The resistive leakage current of the arrester is detected based on the difference between the entire leakage current and the capacitive leakage current(S350).

Abstract: A method for estimating job individual exposed system is provided to present an exposure level in consideration of all magnetic field generation sources which a user contacts in the daily life, thereby obtaining a more practical and correct result. A substantial measured database of a checked researcher used in the estimation equation conduction of a job magnetic field expose amount is built. A genetic algorithm is applied to the built database with a tuning variable including the number of households, an injury colony number, a hybridization probability, and a mutation probability. The genetic algorithm is most suitable for the optimization problem. Accordingly, the most effective numerical solution is obtained. The estimation equation of the job individual magnetic field exposure amount is obtained on the basis of the obtained numerical solution.
