Abstract

It’s been widely used that Synchronize data Sampling with GPS clock. But, the precision should be improved when it’s used for dielectric loss test in a substation. In this article, it’s studied that a portable testing system which based on high-precision sampling synchronously with GPS and wireless. It’s introduced about the theory, design of hardware and software, error of synchronizing sampling. The cause for orthogonal algorithm’s error is analyzed, and a reformative algorithm is proposed to improve the precision. The algorithm’s influence and synchronize performance were studied with comparison. The system’s performance was tested. It shows the system can measure phase difference with very high precision, and the error is less than 0.05%, which can be used for relative dielectric loss measurement.
