Design of a Multi-station Low-voltage Current Transformer Automatic Verification System

Abstract

Manual mode is mostly adopted for traditional verification work aiming at low-voltage current transformer performance. Test is completed on many stations. Instruments and equipment should be manually moved, combined, wired and disconnected for many times, and certificate should be frequently issued, etc., thereby consuming a lot of manpower and material resource with high labor intensity and low work efficiency. In the paper, a multi-station low-voltage current transformer automatic verification system design plan is proposed aiming at the disadvantages of manual verification mode. The low-voltage current transformer is tested comprehensively through transformer comprehensive test control cabinet and transformer comprehensive testing bench. It is characterized by convenient use and high operation efficiency.
