On-board Transformer Calibration System Research

In recent years, the smart grid of our country grows vigorously, the demand fortransformer is also increasing. In school because of the electronic instrument transformerin compared to other transformer pair has the very big advantage, therefore has beenwidely used in the field test. Under such background, how to improve the accuracy of theelectronic transformer pair in school, get the extensive concern of the power industry,also have far-reaching application value.Detecting a transformer in the power equipment plays a very important role, and thesettlement all relevant units in the power industry is the main device. According to therequirement of the electric power industry in our country related policy, when the electricpower industry for the installation of the transformer, must carry on the fieldmeasurement. Normally, the scene of the installation environment is relatively complex,when field measurement was carried out on the transformer, there is often a danger. Andthe need of testing equipment is more, volume and weight also is bigger, wheninstallation requires a lot of manpower and material resources, the efficiency is low.Therefore, to develop an integrated vehicle transformer calibration system study is verynecessary.Many risk factors for transformer on-site inspection and the present situation of thework efficiency is low, at the same time to the current our country of transformer on sitecalibration of several kinds of methods are compared, and the development of on-boardtransformer calibration system is presented. The carrier of this idea is a car, the centralcontrol unit for the digital processor, through the study of the professional modificationof vehicles, equipped with advanced test equipment, communication flow of test lab.Transformer calibration system research for car, can be carried out on the transformeron-site check, can also will need all of the instruments in the car, meet the basicrequirement of the field measurement of transformer, reduce workload, improve theefficiency of improved the field test.
