The following new features and their benefits are introduced in this update:
Line distance protection for series compensated lines is now improved by an extremely fast transient direction detection
based on the well proven RALDA principles.
The high speed fault detection from both line ends together with scheme communication enables fast fault clearance.
REL670 now includes increased number of functional instances whereby protection of two
overhead lines (one as main and another as backup) can be achieved using a single IED.
RET670 now includes a state-of-the art differential protection for phase-shifting transformers.

In terms of solution, the complex phase-shifting transformer is seen as a
single unit and only external CTs and VTs will be required.
The differential protection is self-adaptive to the phase angle and voltage
ratio thereby making it extremely simple to configure, set and deploy.
The single phase and three phase circuit breaker failure protection are
now updated with a flexibility of having several different initiation conditions.
REC670 now includes 12 instances (from earlier 6 instances) of high-impedance differential protection functions.
This increase will now allow coverage of applications with a higher number of zones using one single IED.
All 670 series products now include current/voltage/general delta supervision functionality.
These can be used for delta calculation including vector shift calculation using instantaneous/RMS
magnitudes for usage in applications like comparators or release conditions.
All 670 series products now include current/voltage harmonic monitoring functionality.
These functions are useful to monitor the harmonic distortion, up to 5th harmonic,
total harmonic distortion and total demand distortion.
