Overview Faulted circuit indicators (FCIs) used by the electric utility industry
32、are applied to three-phase underground circuits. For the purpose of this document, faults on these circuits are assumed to be permanent and bolted. This guide will describe the application of FCIs to three-phase, 200 / 600 amp underground distribution circuits. 1.1 Scope This application guide provi
33、des information on what a FCI is designed to do and describes methods for selecting FCIs for three-phase, 200 / 600 amp underground distribution circuits. This application guide will complement the existing single phase application guide. 1.2 Purpose The purpose of this guide is to provide an indust
34、ry document that provides information for the application and use of FCIs on three-phase circuits in the electric power industry.

The Authoritative Dictionary of IEEE Standards, Seventh Edition B6should be referenced for terms not defined in this clause. 2.1 automatic reset faulted circuit indicator: A type of faulted circuit indica
36、tor (FCI) that resets automatically after an operation. Automatic reset control parameters include voltage, current, and time, and combinations 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 re
37、set 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 been sensed. 2.5 fault current: Any current through the sensor, equal to or in excess of the trip current of the faulted circuit indica
38、tor (FCI). 2.6 faulted circuit indicator: A single or multi-phased device designed to sense fault current and provide an indication that the fault current has passed through the power conductor(s) at the point where the FCI sensor is installed. 2.7 FCI components: Faulted circuit indicators (FCIs) c
39、onsist of three basic components. The components are the sensor, the logic circuit, and the display. 2.8 inrush restraint: A faulted circuit indicator (FCI) design feature to minimize false tripping due to current inrush during energization of the circuit. 2.9 logic circuit: A faulted circuit indica
40、tor (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 circu
41、it indicator: A type of fault circuit indicator that requires manual reset by the operator. 2.12 proximity effect: The magnetic induction effect of load or fault current flowing in an adjacent wire, cable, or ground conductor that may cause a faulted circuit indicator (FCI) to misoperate (i.e. false
42、 trip, failed 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 circui
43、t indicator (FCI) indicating an unfaulted state.

All rights reserved. 2.16 reset device: A tool for manually resetting a faulted circuit indica
44、tor (FCI) from a faulted condition to an unfaulted condition. 2.17 reset current or voltage: The nominal value of current or voltage that will cause the indicator of the automatic current or voltage reset faulted circuit indicator (FCI) to change from FAULT to NORMAL indication. 2.18 reset time: The
45、 time required for the faulted circuit indicator (FCI) to return automatically to NORMAL indication after its reset current or voltage has been established, or the set time for an automatic reset FCI to reset has elapsed. 2.19 response time: The time required for the faulted circuit indicator (FCI)
46、to respond to a specified value of fault current. 2.20 sensor: The sensing section of a faulted circuit indicator (FCI) designed to detect a fault condition. 2.21 time reset: A type of automatic reset which resets a faulted circuit indicator (FCI) after a specified time. 2.22 trip current: The actua
47、l value of current in amperes (rms) that will cause the faulted circuit indicator (FCI) to indicate FAULT. 2.23 trip level: The threshold current or rate of rise that will cause the faulted circuit indicator (FCI) to operate. 2.24 tripped faulted circuit indicator (FCI): An FCI that has operated to
48、indicate a fault condition. 2.25 SCADA: An abbreviation for Supervisory Control and Data Acquisition. 2.26 backfeed voltage: Voltage that is present on electrical distribution circuits after interruption of the faulted phase. 2.27 feed current: Current that is present on electrical distribution circ
49、uits after interruption of the faulted phase. 2.28 overcurrent protection: A form of protection that operates when current exceeds a predetermined value. 3.
