The Effects of Salt Water Treating on Dielectric Properties of FRP Composite Insulation Materials

FRP 복합절연재료의 유전특성에 미치는 염수처리의 영향

The purpose of this paper is to evaluate FRP rod for aging, which exposed to salt water and pure at elevated temperature. Dielectric constant and tan .delta. on time and frequency domain were tested to observe how rapidly the FRP rod aged. Dielectric constants of FRP rods with treating time were slightly increased. That of FRP rods with frequency, However, showed strongly the effects of large relaxation time estimated from interfacial polarization a or ionic. It is obvious that absorbed water affects to dielectric and electric properties of FRP with increasing the treating time.
