광센서에 의한 전류전압 측정법
Current and Voltage Measurement using Optical Sensors
초록
The present metering transformer being used for measurement has the characteristics of high reliability and high efficiency. In the future, however, it is thought that the scales of mettering transformer will be larger and the cost of production will increase as the transmission voltage ascends to UHV. And, also, it wilt be not easy to ensure the aseismatic capability. For the purpose of settling these problems, by applying optical sensor technology to electric power systems and by developing optical current transformer and potential transformer, we will realize the saving in energy, reduction of cost prise, improvement in measuring precision.
