Protective Device
Coordination
Study Projects

Protective
devices detect an overload or short circuit in a power system component
and, if found, remove the component from the power system.
A
protective device coordination study is performed to:
-
Select
proper protective devices (relays, circuit breakers and fuses).
-
Calculate
protective relays and circuit breaker trip unit settings.
A
protective device coordination study is performed either during the design
state of a new system, to verify the protective devices will operate correctly
in an existing system, or when the protective devices are not operating
correctly.
Objectives
of the study are:
-
Prevent
damage to the faulty components.
-
Minimize
the damage to the faulty components
-
Selectively
isolate the faulty component so a minimum non-faulty components are removed.
