Research on Optical Fiber Current Transformer in High-Capacity Test System
In high-voltage high-capacity detection systems,the current measurement system is an important component,used for transient data measurement during high-voltage high-current tests on electrical equipment such as switches and fuses,as well as testing key indicators such as breaking capacity and short-circuit resistance.Because the current shunt,electromagnetic current transformer,roche coil and hall sensor used in the traditional high-voltage and high-capacity test system have their own application limitations,they have a direct impact on the accuracy,anti-interference and stability of the measurement system on the measurement results.This paper analyzes the advantages and disadvantages of different types of current acquisition systems in the current high voltage and large capacity testing system,and briefly summarizes the research process of optical fiber current transformer used in the current system,and verifies the feasibility of the product applied to the high voltage and large capacity testing system by comparing the actual introduction of optical fiber current transformer products in the system with the traditional measurement methods.
