Protection Question #1 a. List the four important stages required for the protection of network equipment. b. The characteristics curves of an overcurrent relay, used as part of the protection system of a generator, is shown in Figure #4. The characteristics of a multi-ratio current transformer are shown in Figure #3. By selecting an appropriate CT ratio, determine the relay setting that will allow the generator to operate at maximum load, indicated in table 1, without tripping. c. Based on your selections in section "b" estimate the fastest operating time for the relay to trip during the passage of the minimum and maximum fault currents.
