초록
We researched basic study about electrical characteristics of Zinc Selenide (Faraday Cell), which is known for various temperature of good-performance, that applied measuring current or protecting instrument by Optical Current Transducer, on Gas Insulated Switchgear. Measuring System consists of VCSEL produced 850nm IR Laser, Pin Photo Diode made of GaAs surveyed as Optical Power Meter, and Optical Fibers specified Multi-mode. We observed optical output changes during measurement of currents increasing by 100[A] in range from 0[A] to 1,000[A] and set temperature condition increasing by
