| Abstract: | In order to settle the question of data sampling in current, voltage, power that happened in computer control system of transformer test, the causation of synchr onous error was analyzed, and error-free conditions were got. Math models for the errors in volt age, current and average power measuring were established, which is called Synchronous Software S ample Technology. And some measures to reduce these errors are proposed in this paper. By means of this sampling method, the number of sampling periodicity isn't needed to increase, an d the question that synchronous sample error influences system precision is solved as well. |
