Which of the below statements about protection systems
components and their design criteria is TRUE?
a. The function of a breaker is
to discriminate between normal operation and fault conditions
b. Relays accurately reproduce
power system currents and voltages over wide ranges
c. Instrument transformers
provide lower-level relay inputs that enable relays to be smaller,
simpler and less expensive
d. Selectivity of system protection refers to the ability
to operate rapidly to minimize equipment damage
