Residual magnetic flux can make significant problems in electric power system operation if it is not taken into consideration. The laboratory setup for determining residual magnetic flux value is presented in this paper. The experimental procedure includes only electrical measurements and quantities (voltage and current). Residual magnetic flux value is determined using a low voltage DC source for energization of an unloaded transformer. A simple model of a magnetic core coil or unloaded transformer which consists of a linear resistance in series with a nonlinear inductance is used. Various de-energization magnetic flux values are set before each measurement in order to prove validity of proposed experimental procedure independently of initial condition of magnetic flux. In total, 25 measurements are carried out. Also, the pros and cons of the laboratory setup and experimental procedure are given, as well as plans for future research.
