Abstract
This paper deals with the construction of an interface which is to be placed between a process and a Process Computer. <br><br> The interface shall integrate the process signal during a period which is a multiple of the period of the line-frequency. This means that the disturbance from line-frequency will be completely eliminated. <br><br> The process signal is also to be transformed to the 0-+-10V-interval. <br>The sampling period is 0,1 , 1 or 10 seconds. <br><br> The interface was built in two parts, namely one part consisting of an integrator and amplifiers, and one part consisting of a controlling system. <br><br> Testing of the interface showed that the disturbance from line-frequency was completely eliminated, and that the error in...
