Abstract This paper presents an analysis of the fault current contributions of small‐scale single‐phase photovoltaic inverters under grid‐connected operation and their potential impact on the protection of distribution systems. To conduct this

The measured flicker levels by using the IEC standard 61000-4-15 often far exceed the established compatibility levels, even without the existence of consumer complaints. The poor measurement/complaint correlation due to the use of IEC flickermeter c

The performance of electrical energy meters in non-sinusoidal conditions has been discussed since the early 20th Century and as of yet has not reached a fully comprehensive standardization. Within this context, this paper aims to update the present u

The main flicker source is the irregularly fluctuating loads, specially the AC electric arc furnace (EAF). The random time-varying and nonlinear behavior of the arc is quite difficult to model analytically. The most EAF models are not feasible for fl

This research aims to quantify the skin effect and estimate expressions that well represent the phenomenon for harmonic power flow studies. The primary focus is to validate the behavior of the skin effect at harmonic frequencies ranging from 60 Hz to

A detecção da Falta de Alta Impedância (FAI) em Sistemas de Distribuição (SDs) é uma tarefa árdua que atrai o interesse de empresas e pesquisadores em todo o mundo. A aleatoriedade e a a possibilidade de ambiguidade em relação a outros trans
