2.Definitions
For the purpose of this guide, the following terms and definitions apply. The Authoritative Dictionary ofIEEE Standards,Seventh Edition B6 should be referenced for terms not defined in this clause.
2.1 automatic reset fauled circuit indicator: A type of faulted circuit indicator (FCI) that resetsautomatically after an operation. Automatic reset control paraeters include voltage, current, and time, andcombinations of these three.
2.2 bolted fault: A short circuit condition that assumes zero impedance at the point of the fault.
2.3 current reset: A type of automatic reset in a faulted circuit indicator (FCI) that utilizes current
2.4 indicator: That portion of the faulted circuit indicator (FCI) which indicates fault current has beensensed.
2.5 fault current: Any current through the sensor, equal to or in excess of the trip current of the faultedcircuit indicator (FCI).
2.6 faulted circuit indicator: A single or multi-phased device designed to sense fault current and providean indication that the fault current has passed through the power conductor(s) at the point where the FClsensor is installed.
2.7 FCI components: Faulted circuit indicators (FCIs) consist of three basic components. The componentsare the sensor, the logic circuit, and the display.
2.8 inrush restraint: A faulted circuit indicator (FCl) design feature to minimize false tripping due tocurrent inrush during energization of the circuit.
2.9 logic circuit: A faulted circuit indicator (FCI) internal circuit design for recognizing a fault condition.
This is the section of the FCI that determines if and when a fault condition exists.
2.10 looped circuit: A type of distribution circuit with two or more sources, usually separated by an open
switch.
2.11 manual reset faulted circuit indicator: A type of fault circuit indicator that requires manual reset bythe operator.
2.12 proximity effect: The agnetic induction effect of load or fault current flowing in an adjacent wirecable, or ground conductor that may cause a faulted circuit indicator (FCI) to misoperate (i.e. false tripfailed to trip, or reset incorrectly).
2.13 radial circuit: A type of distribution circuit fed from a single source.
2.14 remote display: A faulted circuit indicator (FCI) that is physically separated from the sensor.
2.15 reset condition: The state of or the act of change of a faulted circuit indicator (FCI) indicating anunfaulted state.
