In this paper, we described the laboratory layout of the optical CT in connection with the measurement of large current for the GIS. The aim of this study is the development and application of optical CT based on Faraday effect. It was used He-Ne laser for light source (633nm) and was used PIN-Photodiode for light receiver. The laser source passes through optical fiber in single mode. We used the polarizer to polarize the light source and the beam splitter to divide the output light, and the optical fiber is connected for the measuring the angle polarized in the magnetic field.

This paper describes the development of sputtered tungsten electrode for discharge tube by making use of Sputtering method using plasma. The Xe discharge tube was designed and fabricated by using sputtered tungsten electrode, and the ICCD(Intensified Charged Coupled Device) and monochromator were used in order to observe the discharge image distribution and to measure the signal intensity. As a result, the emission light form the electrode was spreaded almost uniformly over a wide wavelength band, and the discharge image distribution and the signal intensity show quite a uniform distribution. The emission light from the Xe discharge tube was peaked at 488[nm] and 648[nm].
