On the dependence between the amplitude and time parameters of pulse voltages in general-purpose power-supply systems

Resumo

The existing regulatory requirements to assessment of the voltage pulses in general-purpose power-supply systems as a parameter of electric energy quality are considered. The attention is focused on the fact that GOST (State Standard) 32144-2013 recommends taking into account the statistics related to such characteristics when concluding contracts for electric-energy supply or transmission. The article presents the results of processing of the statistical material obtained using a special device for recording the impulse-voltage parameters. A stable correlation and regression dependence between these parameters has been established. It is shown that this dependence has an exponential character. A method of generating a test voltage pulse is proposed to test the actual resistance of consumers to impulse voltages arising in the power supply circuits.
