REL650 application

REL650 is used for the protection, control and monitoring of overhead lines and cables in
solidly or impedance grounded networks. The IED can be used up to the high voltage
levels. It is suitable for the protection of heavily loaded lines and multi-terminal lines
where the requirement for fast one- and/or three-pole tripping is wanted. Apparatus
control for up to 8 apparatuses with interlocking can be included in one IED by function
block engineering.
The full scheme distance protection provides protection of power lines with high
sensitivity and low requirement on remote end communication. The five zones have fully
independent measuring and setting which gives high flexibility for all types of lines. Load
encroachment and adaptive reach compensation are included.
The modern technical solution offers fast operating time of typically 30 ms.
The multi-shot autoreclose includes priority features for double-breaker arrangements. It
co-operates with the synchronism check function with high-speed or delayed reclosing.
High set instantaneous phase and ground overcurrent, four step directional or non-
directional delayed phase and ground overcurrent, thermal overload and two step under
and overvoltage protection are examples of the available functions allowing the user to
fulfill any application requirement.
The distance phase and ground fault protection, and the directional ground overcurrent
protection can communicate with remote end in any teleprotection communication
scheme.
The advanced logic capability, where the user logic is prepared with a graphical tool,
allows special applications.
Disturbance recording and fault locator are available to allow independent post-fault
analysis after primary disturbances.
Three packages of configured solution have been defined for following applications:
