The Quality Assurance and Online Diagnosis Technology of Automatic Verification System for Transformer

Abstract

Low voltage current transformers are widely used in power system. Such as the records of power consumption, energy trading and industrial load monitoring, is an important measuring component in electric power system of China at the present stage. Whether the low voltage current transformer is accurate or not, related to the power customer's vital interests and the power grid enterprise`s economic benefits, also affects the quality of grid service level and the fulfillment of social responsibilities. To establish a quality assurance system, make the fault detection rate and the percent of pass of the automatic verification system is accordance with the requirements. At the same time, the establishment of online diagnosis system can remind the staff when any failure occurs and help them repairs the fault as soon as possible. It can provide a strong guarantee for the stable operation, management and protection of the automatic verification system.
