automatic reset faulted circuit indicator: (FCI: A type of faulled circuit indicator (FCIFC thatresets automatically after an operation. Automatic reset control parameters include voltage, current,and time, and combinations of these three parameters.
backfeed current: Current that is present on one or more phases of an electrical distribution circuitwhile the phase(s) are disconnected at the source.
backfeed voltage: Voltage that is present on one or more phases of an electrical distribution circuitwhile the phase(s) are disconnected at the source.
bolted fault: A short-circuit condition that assumes zero impedance at the point of the fault.
current reset: A type of automatic reset in a faulted circuit indicator (FCI) that utilizes current.
fault current: Any current through the sensor, equal to or in excess of the trip current of the faultedcircuit indicator (FCI)..
faulted circuit indicator: (FCI): A single or multi-phased device designed to sense fault current andprovide an indication that the fault current has passed through the power conductor(s) at the pointwhere the FCI sensor is installed.
faulted circuit indicator (FCI) components: FCIs consist of three basic components.Thecomponents are ; the sensor, the logic circuit, and the display.
indicator: That portion of the faulted circuit indicator (FCI) which that indicates fault current hasbeen sensed.
inrush restraint: A faulted circuit indicator(FCI) design feature to minimize false tripping due tocurrent inrush during energization of the circuit.
integral display: A display that is built in or mounted on the sensor.
logic circuit: A faulted circuit indicator (FCI) internal circuit design for recognizing a fault condition.This is-The section of the FCl that determines if and when a fault condition exists and determines ifand when reset conditions have been satisfied.
looped circuit: A type of distribution circuit with two or more sources,usually separated by an openswitch.
manual reset faulted circuit indicator (FCI): A type of fault circuit indicator FCI that requiresmanual reset by the operator.
overcurrent protection: A form of protection that operates when current exceeds a predeterminedlevel.
