Měření s impulzním generátorem proudu

Abstract

In this barchelor thesis we will be aquainted with the residual voltage on excess voltage limiter and with impulse current generator SSG-ZUS, with its funcions and with its usage in practice. The thesis is divided into introduction, three chapters, in which we will be aquainted with the impulse current generator and means of the accomplishment the test of the residual voltage on voltage limiter, and the conclusion.

The first chapter deals with the function and the principles with technical description of the limiter excess voltage ABB, then the residual voltage and assessment of the safety level of the residual voltage limiter is described and the order of measurement according to the norm.

The second chapter deals with the description of lightning current impulz. The implulz generator is being described here - its construction, mathematical block diagram of the cut-in, possible kinds of construction of the generator and the calculation of the parameters of chosen cut-in for measuring the residual voltage on the limiter ABB.

The third chapter deals with the results of the masurement of the residual voltage on the ceramic excess voltage limiter, the depicted volt-ampere characteristic and it contains also the description ot the other components, which are used as a work piece for its accurate function. The protocol of this measurement is executed with the evaluation of the whole measurement.
