| Abstract: | This Paper analyses the causes of errors of synchronous sampling by software in low-frequency teSt system, establishes the mathmatical models of method error of testing voltage, current and POwer, and recomrnands the measures to be taken to reduce or eliminate the errors. At last the properity of above mentioned conclusions are Proved by computer simulation. |
