The protection devices MiCOM P631, P632, P633
and P634 are of modular design. The plug-in
modules are housed in a robust aluminum case
and electrically connected via an analog and a
digital bus printed circuit board.
The nominal currents or the nominal voltage,
respectively, of the measuring inputs can be set
with the help of function parameters.
The nominal voltage range of the optical coupler
inputs is 24 to 250 V DC without internal
switching. Optional there are also ranges with
higher switching thresholds available.
The auxiliary voltage input for the power supply is
a wide-range design with a nominal voltage range
of 48 to 250 V DC and 100 to 230 V AC. An
additional version is available for the lower
nominal voltage range of 24 V DC.
All output relays are suitable for both signals and
commands.
The optional PT 100 input is lead-compensated,
balanced and linearized for PT-100 resistance
thermometers per IEC 751.
The optional 0 to 20 mA input provides open-
circuit and overload monitoring, zero suppression
defined by a setting, plus the option of linearizing
the input variable via 20 adjustable interpolation
points.
Two freely selected measured variables (cyclically
updated measured operating data and stored
measured fault data) can be output as a load-
independent direct current via the two optional
0 to 20 mA outputs. The characteristics are
defined via 3 adjustable interpolation points
allowing a minimum output current (4 mA, for
example) for receiver-side open-circuit monitoring,
knee-point definition for fine scaling and a
limitation to lower nominal currents (10 mA, for
example). Where sufficient output relays are
available, a freely selected measured variable can
be output in BCD-coded form via contacts.

Information Interface
Information exchange is done via the local control
panel, the PC interface and 2 optional
communication interfaces.
One of the communication interfaces conforms to
IEC 60870-5-103, IEC 60870-5-101, DNP 3.0 and
Modbus and is intended for integration of MiCOM
P63x with substation control systems.
The 2nd communication interface (COMM2)
conforms to IEC 60870-5-103 and is intended for
remote setting access only.
Clock synchronization can be achieved using one
of the protocols or using the IRIG-B signal input.

Main functions
Main functions are autonomous function groups
and can be individually configured or disabled to
suit a particular application. Function groups that
are not required and have been disabled by the
user are masked completely (except for the
configuration parameter) and functional support is
withdrawn from such groups. This concept
permits an extensive scope of functions and
universal application of the protection device in a
single design version, while at the same time
providing for a clear and straight-forward setting
procedure and adaptation to the protection task
under consideration.
Differential Protection
Amplitude Matching
On the basis of the primary transformer currents,
the MiCOM P63x differential protection devices
can be flexibly adapted to the reference currents
of the protected object. Amplitude matching is by
means of a straight-forward input of the reference
power common to all windings plus the nominal
voltages and the nominal transformer currents for
each winding. The resulting reference currents
and matching factors are automatically deduced
by the device and checked for compatibility with
the internally allowed value ranges.
Vector Group Matching and
Zero-Sequence Filtering
Matching of the MiCOM P63x series differential
protection devices to the vector group of the
protected object is via a straight-forward input of
the relevant vector group identification number.
The mathematical formula to be applied to the
measured values is automatically selected
internally according to the relevant vector group
and zero-sequence filtering is taken into account
simultaneously. For special applications, zero-
sequence filtering may be deactivated separately
for each winding.
Tripping Characteristics
The tripping characteristics of the differential
protection device has two knees (see Figure 4).
The first knee is dependent on the setting of the
basic threshold value Id> and is on the load line
for single-side feed. The second knee of the
tripping characteristic is defined by a setting.
Above the user-selected differential current level
Id>>>, the restraining current is no longer taken
into account.
