Scope and Assumptions Fault codes are indicators of general types of failures. A fault code may not be as specific as other QoS metrics. A fault code may simply indicate the general area of a fault to aid monitoring or troubleshooting of areas that could otherwise be...
1.1 These requirements cover equipment intended to quench arcing faults by creating a lower impedance current path, located within a controlled compartment, to cause the arcing fault to transfer to the new current path. 1.2 These requirements cover equipment that may either be...
1.1 These requirements cover fast operating devices intended to interrupt currents associated with arcing faults, having interrupting times faster than conventional overcurrent devices. 1.2 These requirements cover open type devices that are intended to be installed within power distribution...
This document provides guidance in performing Failure/Fault Analyses in relatively low complexity systems. Methodologies and processes are presented and described for accomplishing Failure/Fault Analyses. ARP4761 provides updated methods and processes for use on civil aircraft safety...

This Standard applies to ground fault circuit interrupters (GFCIs) intended for installation in non-hazardous locations at nominal system voltages of 600 V and less, in accordance with CSA Standard C22.l, Canadian Electrical Code, Part I, in order to automatically deenergize some part of an...
This document provides a description of the associated fault code schema file.
Control systems include many components, such as transducers, sensors, actuators and mechanical parts. These components are required to be operated under some specific conditions. However, due to prolonged operations or harsh operating environment, the properties of these devices may degrade to an...
PURPOSE AND SCOPE This Specification defines National Grid's technical requirements for fault recording. Fault recording equipment is required to provide monitoring of system faults. This Specification describes the functional and performance requirements for fault...
1.1 These requirements cover ground-fault current sensing devices, relaying equipment, or combinations of ground-fault current sensing devices and relaying equipment or equivalent protection equipment for use in ordinary locations that will operate to cause a disconnecting device to...
Scope. This specification covers the Arc Fault Protection System (AFPS) that detects an arc fault in electrical equipment such as switchboards, load centers, motor drives, and produces a signal to automatically trip upstream circuit breakers to isolate the affected section of the...
This standard establishes uniform requirements and criteria for a performance-based fault tree analysis (FTA), including the modeling components, symbols, and analytical objectives. The performance-based aspect of this standard requires that the organizationʼs FTA capability be rated...
