Arc Phenomena in low-voltage current limiting circuit breakers [PDF]

, 2010
Circuit breakers are an important safety feature in most electrical circuits, and they act to prevent excessive currents caused by short circuits, for example. Low-voltage current limiting circuit breakers are activated by a trip solenoid when a critical

PV control system based on short-circuit current

2013 IEEE 8th International Symposium on Applied Computational Intelligence and Informatics (SACI), 2013
The article is focused on specific issues arising for a photovoltaic panel (PV). In this case, the short circuit current is measured to determine the value of prescribed current corresponding to maximum power point. The results obtained by imposing a load resistance with this method are energy maximum possible, thus justifying the usefulness of this ...
