EXPERIMENTAL ASSESSMENT OF COMMUTATION OVER-VOLTAGES IN INDUCTIVE CIRCUITS ON DISCONNECTION
Abstract
The disconnection of inductive circuits from an alternating voltage source is accompanied by the occurrence of over-voltages, which often are hazardous for the components of the electrical circuit. In this paper is described a modern method for studying transitory regimes which occur at the disconnection of inductive circuits, based on a data acquisition system type NI-USB 6003. The software used is LabView and it is also developed by National Instruments, the developer of the data acquisition system. The paper approaches the situation when disconnecting an inductive circuit from an alternating voltage source in the real case and takes into consideration the capacity of the supply cable and eventual capacities which occur between the elements of the circuit. The measurement method leads to the obtaining of diagrams for voltage variation at the coilпїЅs terminals, of the current within the circuit and of the instantaneous power dissipated over the coil for several values of the commuting circuitпїЅs inductivity. In the first part of the paper is performed an analysis on the phenomenon of disconnecting an inductive load from the network, from the analytic point of view. This is performed on an electrical model having concentrated parameters, from which, based on specific equations resulted the values of the current and voltage over the coil. Experimental measurements which led to obtaining real variations were performed using a specific interfaces circuit which is presented within the paper.
