Merjenje lastnosti tokovnih merilnih pretvornikov

LENIČ, TOMAŽ (author), Agrež, Dušan (mentor)

Uvod govori o pomembnosti merjenja električnega toka, opisane pa so tudi najpogostejše vrste merilnih pretvornikov. V nadaljevanju so predstavljeni različni principi merjenja ter z njimi povezani različni tokovni merilni pretvorniki. Na osebnem računalniku v okolju Agilent VEE Pro smo izdelali objektni program za nastavitev laboratorijskih instrumentov za merjenje. Zgradili smo vezave različnih tokovnih merilnih pretvornikov. Z vzorčenjem dveh digitalnih multimetrov smo zajeli vrednosti, s pomočjo vrednosti pa izdelali grafe (karakteristike). Z njimi smo ponazorili pogreške različnih tokovnih merilnih pretvornikov v odvisnosti od različnih velikosti in različnih frekvenc električnega toka.

• Title: Measurements of characteristics of the current measurement transducers

Abstract

Introduction discusses the importance of measuring the electric current, as well as describing the most common types of measurement transducers. The following are the different principles of measurement and related different current measuring transducers. On the PC environment, using Agilent VEE Pro we made object setup of laboratory instruments used for measuring. We have built a circuit with different current measuring transducers. By sampling two digital multimeters values have been captured and from them according graphs (characteristics) were produced. Using these graphs we illustrated errors of different current measurement converters, depending on the different amplitudes and different frequencies of electric current.
