A 5-kV class Adaptive Var Compensator (AVC) was designed. installed, and tested at a rock crushing plant where the reactive power is rapidly va ying. Several novel circuits including optical triggering for the switching of the solid state devices are used in the A VC. The A VC provides reactive power support for cyclic loa&, and maintains the power factor at unity at the point of installation without introducing transients to the system. During the field testing of the AVC, several modifications were made to …
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
