The TMT&FIP applies to testing work on all equipment and systems that are carrying operational telecommunications traffic. This includes bearer circuits carried over Network Rail owned infrastructure. This standard does not apply to train borne equipment where maintained by non- Network Rail...
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...
