3. Differential protection
The function consists of differential protection algorithm,
sensitive differential protection algorithm, check zone
algorithm, open CT algorithm and two supervision algorithms.
Busbar differential protection
This protection function is intended for fast and selective
tripping of faults within protected zone. For each current
input, the CT ratio can be set from the front HMI or via the
parameter-setting tool, PCM600. In this way adaptation to
different CT ratios is provided in the simplest way. The
minimum pick-up value for the differential current is then set
to give a suitable sensitivity for all internal faults. This setting
is made directly in primary amperes. For busbar protection
applications typical setting value for the minimum differential
operating current is from 50% to 150% of the biggest CT.
The settings can be changed from the front HMI or via the
parameter-setting tool, PCM600.
All current inputs are indirectly provided with a restraint
feature. The operation is based on the well-proven RADSS
percentage restraint stabilization principle, with an extra
stabilization feature to stabilize for very heavy CT saturation.
Stability for external faults is guaranteed if a CT is not
