DEVELOPMENT OF DIGITAL FLICKER METER AND SPECIFICATION OF DISTURBANCE PROPAGATION DIRECTION

Unhauzer Attila

Abstract

The number of the non-linear equipments connected to the electrical energy distribution system is rising continuously. These equipments generate harmonic currents and voltages in the network impedances and they are added to the base signal deforming the value and the shape of the main voltage. The distorted voltage increases electrical strain and temperature load of the equipment (engines, transformers, capacitors, links, and cables) connected to the network. Moreover the operation of certain equipments connected to the electrical networks can be disturbed due to distorted voltage caused by noise generation.<br />These days the appearance of disturbance effects has greater and greater significance since entirely new regulations, standards and requirements of the EU have been emerged. On one hand the mentioned standards extend to the measurement methods of electrical networks and on the other hand to the limits of the most important electrical parameters as well. Consequently, it is apparent that more and more modern measurement methods and procedures are regulated which influence indirectly the human health and the continuity of industrial operations.
