Definitions and Standards
Back-up protection
Agenda Low voltage selectivity with ABB circuit breakers
Selectivity (or discrimination)
is a type of coordination of two or
more protective devices in series.
Selectivity is done between
one circuit breaker on the supply side
and one circuit breaker, or more than
one, on the load side.
A is the supply side circuit
breaker (or upstream)
B and C are the load side circuit
breakers (or downstream)
Introduction What is selectivity?
Better selectivity
FAULT CONTINUITY OF SERVICE DAMAGE REDUCTION
Fast fault elimination
Reduce the stress and prevent damage
Minimize the area and the duration of power loss
Introduction Protection system philosophy
Selective coordination among devices
is fundamental for economical and technical reasons
It is studied in order to:
rapidly identify the area involved in the problem;
bound the effects of a fault by excluding just the affected zone of the network;
preserve the continuity of service and good power quality to the sound parts of the network;
provide a quick and precise identification of the fault to the personnel in charge of maintenance or to management system, in order to restore the service as rapidly as possible;
achieve a valid compromise between reliability, simplicity and cost effectiveness.
Main purposes of coordination Selectivity purpose
The definition of selectivity
Trip selectivity (for overcurrent) is a coordination between the operating characteristics of two or more overcurrent protection
devices, so that, when an overcurrent within established limits
occurs, the device destined to operate within those limits trips
whereas the others do not trip
IEC 60947-1 Standard: Low voltage equipment
Part 1: General rules for low voltage equipment
Standards definition Selectivity
IEC 60947-1
def. 2.5.23
In occurrence of a fault
(an overload or a short circuit)
if selectivity is provided
only the downstream circuit
breaker opens.
Overcurrent selectivity Example
All the system is out of service!
In occurrence of a fault
(an overload or a short circuit)
if selectivity is not provided
both the upstream and the
downstream circuit breakers
could open
Overcurrent selectivity Example
A and B connected in series:
partial selectivity and total selectivity.
Standards definition Partial and total selectivity
IEC 60947-2
def. 2.17.2 - 2.17.3
Partial selectivity is an overcurrent selectivity where, in the presence of two protection devices against overcurrent in series,
the load side protection device carries out the protection up to a
given level of overcurrent, without making the other device trip.
B opens only according to fault current
lower than a certain current value;
values equal or greater than Is
will give the trip of both A and B.
Is is the ultimate
selectivity
value!
Is = ImA
Standards definition Partial selectivity
Only B trips for every current value
lower or equal to the maximum
short-circuit current.
Total selectivity is an overcurrent selectivity where, in the presence of two protection devices against overcurrent in series,
the load side protection device carries out the protection without
making the other device trip.

Circuit breaker A will be set to a value which does not
trip for faults which occur on the load side of B.

Back-up protection Back-up protection
Agenda Low voltage selectivity with ABB circuit breakers
Back-up protection (or cascading)
is a type of coordination of two protective
devices in series which is done in electrical
installations where continuous operation is
not an essential requirement.
Back-up protection What is back-up protection?
Back-up protection
excludes the use
of selectivity!!!
The definition of back-up is given by the
Back-up is a coordination of two overcurrent protective devices in series, where the protective device on the supply
side, with or without the assistance of the other protective
device, trips first in order to prevents any excessive stress on
downstream devices.
IEC 60947-1 Standard: Low voltage equipment
Part 1: General rules for low voltage equipment
Back-up protection Standards definition
IEC 60947-1
def. 2.5.24
Back-up is used by those who need
to contain the plant costs
The use of a current-limiting circuit
breaker on the supply side
permits the installation of lower performance
circuit breakers on the load side
Both the continuity of service and the selectivity are sacrificed

The Medium Voltage section of the project can be drawn by the Macros
of the typical units of the Unimix switchboard or by Objects for more
flexibility
To pass to the Low Voltage section it is necessary to use the
transformers (when a low voltage section is not needed, the drawing
can be completed with MV Loads or Motors)
