Essential details：REF615E-1G HBFDACADABC1BNN21G Feeder Protection and Control
REF615 is a dedicated feeder IED (intelligent electronic device) designed for the protection, control, measurement and supervision of utility substations and industrial power systems including radial, looped and meshed distribution networks with or without distributed power generation. REF615 is a member of ABB’s Relion® product family and part of its 615 protection and control product series. The 615 series IEDs are characterized by their compactness and withdrawable-unit design.
Re-engineered from the ground up, the 615 series has been designed to unleash the full potential of the IEC 61850 standard for communication and interoperability between substation automation devices.
The IED provides main protection for overhead lines and cable feeders in distribution networks.
The IED is also used as back-up protection in applications, where an independent and redundant protection system is required.
Depending on the chosen standard configuration, the IED is adapted for the protection of overhead line and cable feeders in isolated neutral, resistance earthed, compensated and solidly earthed networks. Once the standard configuration IED has been given the applicationspecific settings, it can directly be put into service.
The 615 series IEDs support a range of communication protocols including IEC 61850 with GOOSE messaging, IEC 60870-5-103, Modbus® and DNP3.

REF615E-1G HBFDACADABC1BNN21G Feeder Protection and Control
REF615 is available in nine alternative standard configurations. The standard signal configuration can be altered by means of the graphical signal matrix or the graphical application functionality of the Protection and Control IED Manager PCM600.
Further, the application configuration functionality of PCM600 supports the creation of multi-layer logic functions using various logical elements, including timers and flip-flops. By combining protection functions with logic function blocks, the IED configuration can be adapted to userspecific application requirements.
The IED offers directional and non-directional overcurrent and thermal overload protection as well as directional and non-directional earth-fault protection. Some standard configurations allow as an option admittance-based, harmonics-based or wattmetric-based earth-fault protection to be used in addition to directional earth-fault protection. Further, the IED features sensitive earth-fault protection, phase discontinuity protection, transient/intermittent earth-fault protection, overvoltage and undervoltage protection, residual overvoltage protection, positive-sequence undervoltage and negativesequence overvoltage protection. Frequency protection, including overfrequency, underfrequency and frequency rate-of-change protection, is offered in IEDs with standard configurations H and J. The IED also incorporates optional three-pole multi-shot auto-reclose functions for overhead line feeders.
Enhanced with optional hardware and software, the IED also features three light detection channels for arc fault protection of the circuit breaker, busbar and cable compartment of metalenclosed indoor switchgear.
The arc-fault protection sensor interface is available on the optional communication module.
Fast tripping increases staff safety and security and limits material damage in an arc fault situation.
