are used extensively by utilities, in order to have
different functions operating on pre-set values.
Hardware switches are however sources for
maintenance issues, lower system reliability and an
extended purchase portfolio. The selector switch
function eliminates all these problems.
Selector mini switch VSGAPC
The Selector mini switch (VSGAPC) function block is a
multipurpose function used for a variety of applications,
as a general purpose switch.
VSGAPC can be controlled from the menu, from a symbol
on the single line diagram (SLD) on the local HMI or from
Binary inputs.
Generic communication function for Double Point
indication DPGAPC
Generic communication function for Double Point
indication (DPGAPC) function block is used to send
double point position indications to other systems,
equipment or functions in the substation through IEC
61850-8-1 or other communication protocols. It is
especially intended to be used in the interlocking
station-wide logics.
Single point generic control 8 signals SPC8GAPC
The Single point generic control 8 signals (SPC8GAPC)
function block is a collection of 8 single point
commands that can be used for direct commands for
example reset of LEDs or putting IED in "ChangeLock"
state from remote. In this way, simple commands can be
sent directly to the IED outputs, without confirmation.
Confirmation (status) of the result of the commands is
supposed to be achieved by other means, such as binary
inputs and SPGAPC function blocks. The commands can
be pulsed or steady with a settable pulse time.
Automation bits, command function for DNP3.0
AUTOBITS
Automation bits function for DNP3 (AUTOBITS) is used
within PCM600 to get into the configuration of the
commands coming through the DNP3 protocol. The
AUTOBITS function plays the same role as functions
GOOSEBINRCV (for IEC 61850) and MULTICMDRCV (for
LON).
Single command, 16 inputs
The IEDs can receive commands either from a
substation automation system or from the local HMI.
The command function block has outputs that can be
used, for example, to control high voltage apparatuses
or for other user defined functionality.

5. Differential protection
High impedance differential protection, single phase
HZPDIF
High impedance differential protection, single phase
(HZPDIF) functions can be used when the involved CT
cores have the same turns ratio and similar magnetizing
characteristics. It utilizes an external CT secondary
current summation by wiring. Actually all CT secondary
circuits which are involved in the differential scheme are
connected in parallel. External series resistor, and a
voltage dependent resistor which are both mounted
externally to the IED, are also required.
The external resistor unit shall be ordered under IED
accessories in the Product Guide.
HZPDIF can be used to protect tee-feeders or busbars,
reactors, motors, auto-transformers, capacitor banks
and so on. One such function block is used for a high-
impedance restricted earth fault protection. Three such
function blocks are used to form three-phase, phase-
segregated differential protection.
6. Impedance protection
Automatic switch onto fault logic, voltage and
current based ZCVPSOF
Automatic switch onto fault logic (ZCVPSOF) is a
function that gives an instantaneous trip at closing of
breaker onto a fault. A dead line detection check is
provided to activate the function when the line is dead.
7. Wide area measurement system
Synchrophasor report, 8 phasors
Configuration parameters for IEEE 1344 and IEC/
IEEE 60255-118 (C37.118) protocol PMUCONF
The IED supports the following IEEE synchrophasor
standards:
• IEEE 1344-1995 (Both measurements and data
communication)
• IEEE Std IEC/IEEE 60255-118 (C37.118) (Both
measurements and data communication)
• IEEE Std IEC/IEEE 60255-118 (C37.118) and IEC/IEEE
60255-118 (C37.118).1a-2014 (Measurements)
• IEEE Std IEC/IEEE 60255-118 (C37.118) (Data
communication)
PMUCONF contains the PMU configuration parameters
for both IEC/IEEE 60255-118 (C37.118) and IEEE 1344
protocols. This means all the required settings and
parameters in order to establish and define a number of
TCP and/or UDP connections with one or more PDC
