The Research of Online Calibration Techniques for Potential Transformer
Preview AbstractAs the construction of smart grid, condition check of power equipment has been develop quickly. Actually, many problems had been appeared on field condition check of power equipment. This paper proposed one on line calibration system to measure the error data of CVT in substation. This measure method used the secondary single of tank-type PT as the reference standard to compare the output of CVT whiles all equipments of substations operation. By contrast the error data of delivery test and on line check it can be understand that the error data from on line calibration system meet theoretical trend of error data of CVT error curve. This result had been proved the correctness of the on line calibration system.
