1、前言用光的方法测量电流的互感器,特别是在高电压电力部门的实用研究,已经在各个研究所进行。由于在光通信领域中光器件的发展,已经掌握了外围实用元件。虽说对传感元件还不十分满意,但由于使用了这些外围实用元件,使一般测量用的这种互感器成为可能。它可做非接触测量,低损耗测量及高频测量,且具有耐噪声好、传感器部分体积小等特点。本文从测量的观点,叙述测量电流用的光互感器(光电流互感器、光CT)的实用现状。
1. Preface The practical method of measuring current transformers, especially in the high-voltage power sector, has been carried out in various institutes. Due to the development of optical devices in the field of optical communications, peripheral practical components have been mastered. Although the sensor components are not yet very satisfied, but due to the use of these peripheral practical components, so that general measurement of this transformer possible. It can do non-contact measurement, low loss measurement and high frequency measurement, and has good resistance to noise, the sensor part of the small size and so on. This article from the measurement point of view, describes the practical use of optical current transformer (photocurrent transformer, optical CT) for measuring current.
