Abstract
A traditional method of periodical measurement of insulation resistance in live DC networks is a so called “three voltmeters” method. Similar procedure with use of an ammeter is described. Formulas for insulation equivalent resistance calculation are derived with help of Thevenin’s theorem. Few other methods as well as other unconventional ideas are presented. Evaluation of possible errors of respective measurement methods is given. This assessment may be useful for selection of adequate measurement procedures in practical applications.
